I'm working on C++\CLI that someone else started. The solution is made up of 3 C projects and 1 C++\CLI project that uses them.
I've duplicated the C++\CLI project and change it name and ProjectGUID property in the vcxproj file.
The problem is I still get the error listed bellow.
How can I fix this?
Warning 1 warning MSB8028: The intermediate directory (Debug\) contains files shared from another project (my_project.vcxproj). This can lead to incorrect clean and rebuild behavior. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppBuild.targets 388 5 seebo_prod_line_tool
Same problem here, solved by
Deleting all Debug\ and Release\ folders (there were more of them in subfolders where I didn't expect them)
Changing the .sln file manually to fix the name of a referenced C++ project (.vcxproj) which apparently was not renamed when renaming the project in Visual Studio
My suggestion is to make sure the intermediate directory for each project is different (as suggested by someone else earlier.)
To do this,
Open the project's Properties dialog
Under Configuration Properties, select General
Make sure the Intermediate Directory for this project is unique to this project.
I ran into this problem because using previous versions of Developer Studio I had a host of companion projects but wanted all of them to put their output in a common "Release" folder. Inadvertently I had set the same common release folder settings in the Intermediate Directory path for some of the projects (but not all).
I found you can disable these types of warnings by added the following to the project file:
<PropertyGroup>
<IntDirSharingDetected>
None
</IntDirSharingDetected>
</PropertyGroup>
I myself also encountered this kind of warning.. But I obtained this in a different situation, I renamed my whole solution/project via IDE and thus making another copy of an entirely different project. So what I have here is a total of two projects sharing one common resource, source and header files. This makes this warning pop up.
I fixed this by deleting the files associated with the project, which you renamed previously. Delete these INSIDE the DEBUG folder. In your case, try deleting all 'my_project' files, regardless of any file extensions because it shares resource files to your duplicated project.
The cause of this problem is copying an intermediate directory that was created by Visual Studio, and that already contains files from a previous build. It is not a problem in the project settings, but a problem caused by the existence of unexpected files from another project. In this context the warning is benign, but annoying.
The minimal solution is to find and delete each such file. The simpler solution is usually to "super clean": delete every directory created by Visual Studio (with names like bin, obj, x64, x86, Debug, Release and so on), and allow VS to re-create them during the normal build process.
I have experienced this problem as well, and for me, the cause was that there were multiple libname.tlog directories inside the intermediate build folder. These directories contain libname.lastbuildstate files that I assume are used for dependency checking. Doing a Clean of the project I don't think will delete these extra directories.
So in this case I was able to delete the libname.tlog directories and build again. I don't know how it got into the state of having multiple directories inside each intermediate directory -- perhaps they were created when I updated the VS version.
I have read this post thoroughly: How does Visual Studio's source control integration work with Perforce? and found it very informative. However, I have a specific issue that is blocking my use of Perforce in VS.
For the most part, I have no complaints about the plug-in (I'm still using the P4VSCC plug-in because the new plug-in requires conversion by the entire team which can't happen at this time). Once I understood the idiosyncracies, I've had only one problem working with the plug-in.
Our solutions contains many projects that are built into a single deployment package. As such, each assembly is versioned the same. To accomodate this, and other common aspects, we have defined a common "SharedVersionInfo.cs" file which contains the AssemblyVersion and AssemblyFileVersion attributes typically found in the AssemblyInfo.cs file. This file is stored in an Assets folder beneath the solution folder and added to each project's Properties folder as a linked file. This works great from a version management perspective as we only have to change the version in one place and all assemblies are updated. However, Perforce has a problem with this when a new developer first opens the solution or when a new project is added. The only remedy we have currently is to remove all of the linked files (there are 3 per project in this solution), bind the project to source control, then re-add the linked files.
This isn't such a big deal when we add a new project but the solution contains 80 projects (and counting), so this isn't a viable remedy for a new developer!
My understanding is that the problem has to do with where VS thinks the binding root for each project is. After some research, I was led to find where the MSSCCPRJ.SCC files are for the projects. I found there are numerous SCC files scattered throughout the solution structure. So...
First question: Why are there multiple MSSCCPRJ.SCC files in my solution structure?
We also have several shared/common projects that we use in our solutions. This leads to the following folder structure:
/Source
/CommonTools
/ProjectA
ProjectA.csproj
/ProjectB
ProjectB.csproj
/MySolution
/Assets
SharedVersionInfo.cs
/Project1
Project1.csproj
/Project2
Project2.csproj
:
/ProjectZ
ProjectZ.csproj
MySolution.sln
Where both ProjectA and ProjectB are part of MySolution.sln
Second Question: How can I setup the bindings so the /Source folder is considered the root? This would ensure that all projects included in the solution are under the same binding root. Perforce considers this folder to be the root, how do I get VS and the plug-in to do the same?
Since no one else has offered up a solution, I thought I'd follow-up with my own findings for anyone else that comes across the thread.
First, I still have no idea why Visual Studio creates multiple MSSCCPRJ.SCC files but these are the key to establishing the "binding root" for a solution. It is critical that this file exist at the highest level necessary so that ALL of the projects in the solution are in sub-folders relative to the location of this file. In my example above, the MSSCCPRJ.SCC needed to be located in the /Source folder. Having it in the /MySolution folder caused the original problem when adding projects from /CommonTools into the solution.
That said, resolving the issue was no easy task. I had to manually edit the .sln and all of the .csproj files in Notepad. What I found was that some of the .csproj files had the following elements identifying the source control settings:
<SccProjectName>SAK</SccProjectName>
<SccLocalPath>SAK</SccLocalPath>
<SccAuxPath>SAK</SccAuxPath>
<SccProvider>SAK</SccProvider>
I don't know what SAK stands for, but my understanding is this tells Visual Studio to use the binding information contained in the .sln file.
I had to change these to:
<SccProjectName>Perforce Project</SccProjectName>
<SccLocalPath>..\..</SccLocalPath>
<SccAuxPath />
<SccProvider>MSSCCI:Perforce SCM</SccProvider>
where the SccLocalPath value is the relative path from the .csproj file to the MSSCCPRJ.SCC file.
I also had to change the SccLocalPathX and SccProjectFilePathRelativizedFromConnectionX statements for each project in the .sln file. The SccLocalPathX value should be the relative path from the .sln file to the MSSCCPRJ.SCC file - a dot (.) if in the same folder. SccProjectFilePathRelativizedFromConnectionX should be the relative path from the binding root to the .csproj file.
I wish I could say that having that in place, I never had to repeat these steps. Unfortunately, I still have to go in and make corrections every time I added a new project to the solution. Visual Studio still wants to use SAK for the elements in the .csproj file and sometimes the values in the .sln file aren't quite right.
But, at least I know what to look for and what needs to be done to achieve my goals. If anyone else has a better solution or a way to configure VS and/or Perforce so these settings are created correctly up-front, I'll gladly give credit.
Hope that helps...
I have been in this situation quite a few times where visual studio does not honor the Additional Include Directories when it comes to lib and header source files. For example, I just downloaded MyGUI source code and made sure the include directories were correct. I even put them to absolute paths, Visual Studio still complained that it could not find specific header files.
Does anybody experience the same thing with projects, and if so, is there a solution to this problem?Blockquote
EDIT: My apologies for not being able to explain fully. I know that the library and source files have different include directories. The project that I received had correct directory paths for the Additional Include Directories and Additional Library Directories but Visual Studio still failed to recognize them properly. I can right click and open the header file within Visual Studio but when compiling it still complains it cannot find the required header files. I regularly make projects relying on a framework I myself programmed, so I am quite familiar with how to set up dependencies. This is however the second time this seems to be happening. I don't recall which 3rd party project I was trying to compile last time, but Visual Studio simply refused to believe that the Additional Include Directories paths is where it should look for the header files. I am not sure how to give the complete details of this particular library (MyGUI) but I can point you to the website where you can download it to try and see if it is able to find the header files that are included in the project (if it doesn't compile, that is fine, and it is probably because of additional dependencies, but it should at least be able to find files in the common folder, especially when I put absolute paths in Additional Include Directories)
This happened to me once. It turned out the inconsistency of the Debug vs Release builds. When I modified one build, the other build was being compiled. Please set both builds with same include folders and see if it works. Good luck.
I've just spent some hours battling with failing #include paths in the compiler, inconsistencies between the compiler and intellisense.
What I finally discovered was that in the properties of the *.cpp file -- not the project, but the individual *.cpp file -- the "Additional Include Directories" property was blank. I had to explicitly set it to "inherit from from parent or project defaults" -- there's a checkbox near the lower-left corner of the dialog for editing the directory path.
I had copied this file from another project and used "Add > Existing Item..." to add it to the current project. My hypothesis was that maybe the "Existing Item" procedure skipped a property initialization step that "New Item" would normally perform. But I just tested that hypothesis by Adding another Existing and a New. Both of these files had their property set to inherit from the project, so I don't have an explanation for why my problem file was not initially set to inherit.
Anyway ... after much frustration, found and fixed that one.
I have found (stumbled) on the solution (I think). It has something to do with the character limit imposed by the OS. Although the limit should be 260, for me it falls in the below 150, see this discussion and links to it. I downloaded and unzipped the file to C:\Users\MyUserName\My Documents\Downloads\Downloads From Chrome\MyGui3.0...[and so on]. I learned quite some time ago not to try to compile projects under such long paths, but this time it completely slipped my mind as VS did not give me a warning at all and pointed me in the wrong direction. Anyway, cutting and pasting the project to D:\ fixed the issue. I am not going to checkmark the answer however until someone confirms this.
I have the same problem : Can't find .lib file even though I've added the additional include directory.
From an answer of Additional include directory in Visual studio 2015 doesn't work, I tried:
delete the .suo file and restart VS
Then it works for me.
I had this issue too. Just like sam said - this string value containing path to your framework includes has to be the same for the Debug and Release configurations. So the best way is to choose "Configuration:All Configurations" and "Platform:All Platforms" from the two context checklists on the top of the project properties window before typing it in, or copying from windows explorer adress bar.
Can you elaborate on this? If I recall, there are at least two places in Visual Studio where you can configure this:
Per-installation: Tools/Options/Projects and Solutions/VC++ Directories)
Per-project: Project/Properties/Configuration Properties/"C/C++"/General/Additional Include Directories
If you're adding the include directories per-project (#1), which I think you are, and then trying to include from another project, this will obviously not work. Try adding them at the per-installation level and see if it works.
Also, this may sound stupid/simplistic, but make sure the path is right (i.e. copy-paste into Explorer's path bar and see if the header files are in that folder).
If by lib files you mean library (.lib) files, the directory location is not specified through C/C++/General/Additional Include Directories but rather through Linker/General/Additional Library Directories.
It's logical if you think about it. C/C++ options are all compilation options, settings involved with compiling .cpp and .h files. Linker options are all linking options, settings involved with linking up .obj and .lib files.
I had the same symptoms in my c++ project. Navigating from header to header went fine, but after toggling to the source file of a header (let's say foo.cpp), then the navigation to an #include <bar.cpp> in that source file failed. I got the following error:
File 'bar.cpp' not found in the current source file's directory or in build system paths.
After research I noticed that the system build path given in the error where not extended with the include paths of the project. In other words: IntelliSense didn't know that the source file (foo.cpp) was part of the project, and therefore it didn't use the include paths of the project to search for the #include <bar.cpp>.
The fix for me was creating a file intelliSense.cpp (file name doesn't matter) that is part of the project, but excluded from the build. This file contains an include for each source file. ex:
#include <foo.cpp>
#include <bar.cpp>
...
This way IntelliSense knows that these source files are part of the project, and will therefore use the include paths of the project to resolve the #includes in those source files.
For me the issue was that .vcxproj Project file was read-only and after I added my directory to "Additional directories", the project file did not actually change. I was surprised that VS did not complain about this file being read-only.
So after I made that file write-able I could compile my project.
Here is another 'I had the same...' in vs2015.
For me it turned out that the active setting is also depending on the 'solution configuration' and 'solution platform'. That makes 4 settings which all should be identical.
That solved the problem in my case.
I realize this question is over 10 years old at this point, but I also just ran into this issue and none of the answers fit my scenario. After some playing with my IDE (VS 2019) for a few minutes I realized that the cpp file I was using had it's platform set to Win32, but the libs I was trying to use were built for x64.
As others have stated, make sure your project's configuration is set to
-"All Configurations" when you add the necessary paths to your project as that can also be an issue. I imagine my issue will not be as common, but I figured it was worth sharing. I hope this helps someone else in the future.
One more possible reason not mentioned earlier: make sure you are configuring properties of the correct project in a multi-project solution.
My problem was that I had a solution of two projects each using the same file with includes. Turns out that I correctly configured 'Additional Include Directories' only for one of two projects and totally forgot about another one. Of course error message was stating that only the second project and not the first one had problems.
If I add a new file to a project under TFS source control, it will check out the project file and the corresponding .vspscc file for that project file.
The project file itself changes (to include the new file), but the .vspscc file doesn't change at all. Why bother checking it out? Is there a way to disable it from being checked out and if there is, should I?
It gets checked out because under certain conditions it will be modified..and thus they checked it out as a matter of default. I wouldn't worry about it..it's not hurting anything, and if you disable it, it might bite you badly in the future in a bizarre way.
According to this post of Ben Ryan:
Team Foundation uses these to store lists of files that have been excluded from source control. We leveraged some of the existing SCC integration layer in Visual Studio to integrate Team Foundation, and these files were one of the carryovers. I'll have to check into what the logic was in breaking out these SCC settings into separate files as opposed to putting them in the solution and project files' SCC sections.
This file is a holdover from past VSS/TFS implementations, like Paulo Santos posted.
On the solution level, I have found no functional use for these files. In 10 years of using TFS, I have never seen that file altered. You can delete these .VSSCC files, as I commonly do for my closed source solutions.
But if you delete the solution-level .vsscc file, you will get a non-destructive error message on the first time open of the solution file...only after a new branch is created. All subsequent solution opening will not show the error message again.
My TFS setup standards have the solution file alone in the root folder, all projects are under sub-folders. Since those .vsscc files double the number of files in my root, I always delete them.
On a project level, I leave those files, as my team never opens project files directly, only solution .SLN files.
For my team, I prefer programmer ease of opening solutions over that one-time error message.
Visual Studio solutions contain two types of hidden user files. One is the solution .suo file which is a binary file. The other is the project .user file which is a text file. Exactly what data do these files contain?
I've also been wondering whether I should add these files to source control (Subversion in my case). If I don't add these files and another developer checks out the solution, will Visual Studio automatically create new user files?
These files contain user preference configurations that are in general specific to your machine, so it's better not to put it in SCM. Also, VS will change it almost every time you execute it, so it will always be marked by the SCM as 'changed'.
I don't include either, I'm in a project using VS for 2 years and had no problems doing that. The only minor annoyance is that the debug parameters (execution path, deployment target, etc.) are stored in one of those files (don't know which), so if you have a standard for them you won't be able to 'publish' it via SCM for other developers to have the entire development environment 'ready to use'.
You don't need to add these -- they contain per-user settings, and other developers won't want your copy.
Others have explained why having the *.suo and *.user files under source control is not a good idea.
I'd like to suggest that you add these patterns to the svn:ignore property for 2 reasons:
So other developers won't wind up
with one developer's settings.
So when you view status, or commit
files, those files won't clutter the code base and obscure new files you need to add.
We don't commit the binary file (*.suo), but we commit the .user file. The .user file contains for example the start options for debugging the project. You can find the start options in the properties of the project in the tab "Debug". We used NUnit in some projects and configured the nunit-gui.exe as the start option for the project. Without the .user file, each team member would have to configure it separately.
Hope this helps.
Since I found this question/answer through Google in 2011, I thought I'd take a second and add the link for the *.SDF files created by Visual Studio 2010 to the list of files that probably should not be added to version control (the IDE will re-create them). Since I wasn't sure that a *.sdf file may have a legitimate use elsewhere, I only ignored the specific [projectname].sdf file from SVN.
Why does the Visual Studio conversion wizard 2010 create a massive SDF database file?
No, you should not add them to source control since - as you said - they're user specific.
SUO (Solution User Options): Records
all of the options that you might
associate with your solution so that
each time you open it, it includes
customizations that you
have made.
The .user file contains the user options for the project (while SUO is for the solution) and extends the project file name (e.g. anything.csproj.user contains user settings for the anything.csproj project).
This appears to be Microsoft's opinion on the matter:
Adding (and editing) .suo files to source control
I don't know why your project stores the DebuggingWorkingDirectory in
the suo file. If that is a user specific setting you should consider
storing that in the *.proj.user filename. If that setting is shareable
between all users working on the project you should consider storing
it in the project file itself.
Don't even think of adding the suo file to source control! The SUO
(soluton user options) file is meant to contain user-specific
settings, and should not be shared amongst users working on the same
solution. If you'd be adding the suo file in the scc database I don't
know what other things in the IDE you'd break, but from source control
point of view you will break web projects scc integration, the Lan vs
Internet plugin used by different users for VSS access, and you could
even cause the scc to break completely (VSS database path stored in
suo file that may be valid for you may not be valid for another user).

By default Microsoft's Visual SourceSafe does not include these files in the source control because they are user-specific settings files. I would follow that model if you're using SVN as source control.
Visual Studio will automatically create them. I don't recommend putting them in source control. There have been numerous times where a local developer's SOU file was causing VS to behave erratically on that developers box. Deleting the file and then letting VS recreate it always fixed the issues.
No.
I just wanted a real short answer, and there wasn't any.
On the MSDN website, it clearly states that
The solution user options (.suo) file contains per-user solution
options. This file should not be checked in to source code control.
So I'd say it is pretty safe to ignore these files while checking in stuff to your source control.
I wouldn't. Anything that could change per "user" is usually not good in source control. .suo, .user, obj/bin directories
These files are user-specific options, which should be independent of the solution itself. Visual Studio will create new ones as necessary, so they do not need to be checked in to source control. Indeed, it would probably be better not to as this allows individual developers to customize their environment as they see fit.
You cannot source-control the .user files, because that's user specific. It contains the name of remote machine and other user-dependent things. It's a vcproj related file.
The .suo file is a sln related file and it contains the "solution user options" (startup project(s), windows position (what's docked and where, what's floating), etc.)
It's a binary file, and I don't know if it contains something "user related".
In our company we do not take those files under source control.
They contain the specific settings about the project that are typically assigned to a single developer (like, for example, the starting project and starting page to start when you debug your application).
So it's better not adding them to version control, leaving VS recreate them so that each developer can have the specific settings they want.
.user is the user settings, and I think .suo is the solution user options. You don't want these files under source control; they will be re-created for each user.
Others have explained that no, you don't want this in version control. You should configure your version control system to ignore the file (e.g. via a .gitignore file).
To really understand why, it helps to see what's actually in this file. I wrote a command line tool that lets you see the .suo file's contents.
Install it on your machine via:
dotnet tool install -g suo
It has two sub-commands, keys and view.
suo keys <path-to-suo-file>
This will dump out the key for each value in the file. For example (abridged):
nuget
ProjInfoEx
BookmarkState
DebuggerWatches
HiddenSlnFolders
ObjMgrContentsV8
UnloadedProjects
ClassViewContents
OutliningStateDir
ProjExplorerState
TaskListShortcuts
XmlPackageOptions
BackgroundLoadData
DebuggerExceptions
DebuggerFindSource
DebuggerFindSymbol
ILSpy-234190A6EE66
MRU Solution Files
UnloadedProjectsEx
ApplicationInsights
DebuggerBreakpoints
OutliningStateV1674
...
As you can see, lots of IDE features use this file to store their state.
Use the view command to see a given key's value. For example:
$ suo view nuget --format=utf8 .suo
nuget
?{"WindowSettings":{"project:MyProject":{"SourceRepository":"nuget.org","ShowPreviewWindow":false,"ShowDeprecatedFrameworkWindow":true,"RemoveDependencies":false,"ForceRemove":false,"IncludePrerelease":false,"SelectedFilter":"UpdatesAvailable","DependencyBehavior":"Lowest","FileConflictAction":"PromptUser","OptionsExpanded":false,"SortPropertyName":"ProjectName","SortDirection":"Ascending"}}}

Using Rational ClearCase the answer is no. Only the .sln & .*proj should be registered in source code control.
I can't answer for other vendors. If I recall correctly, these files are "user" specific options, your environment.
Don't add any of those files into version control. These files are auto generated with work station specific information, if checked-in to version control that will cause trouble in other work stations.
No, they shouldn't be committed to source control as they are developer/machine-specific local settings.
GitHub maintain a list of suggested file types for Visual Studio users to ignore at https://github.com/github/gitignore/blob/master/VisualStudio.gitignore
For svn, I have the following global-ignore property set:
*.DotSettings.User
*.onetoc2
*.suo .vs PrecompiledWeb thumbs.db obj bin debug
*.user *.vshost.*
*.tss
*.dbml.layout
As explained in other answers, both .suo and .user shouldn't be added to source control, since they are user/machine-specific (BTW .suo for newest versions of VS was moved into dedicated temporary directory .vs, which should be kept out of source control completely).
However if your application requires some setup of environment for debugging in VS (such settings are usually kept in .user file), it may be handy to prepare a sample file (naming it like .user.SAMPLE) and add it to source control for references.
Instead of hard-coded absolute path in such file, it makes sense to use relative ones or rely on environment variables, so the sample may be generic enough to be easily re-usable by others.
If you set your executable dir dependencies in ProjectProperties>Debugging>Environment, the paths are stored in '.user' files.
Suppose I set this string in above-mentioned field: "PATH=C:\xyz\bin"
This is how it will get stored in '.user' file:
<LocalDebuggerEnvironment>PATH=C:\xyz\bin$(LocalDebuggerEnvironment)</LocalDebuggerEnvironment>
This helped us a lot while working in OpenCV. We could use different versions of OpenCV for different projects. Another advantage is, it was very easy to set up our projects on a new machine. We just had to copy corresponding dependency dirs. So for some projects, I prefer to add the '.user' to source control.
Even though, it is entirely dependent on projects. You can take a call based on your needs.
