I have a C++ (Brew C++) project in MVSC++ 10 which compiles in debug build but not in release build, but I cannot fathom out why not.
The problem is that header files within a certain directory cannot be found, the directory structure is:
.mak
.sln
etc.
/inc/A/m.h
/inc/B/n.h
/inc/C/o.h
/inc/util/html/a.h
/inc/util/html/b.h
/src/A/
/src/B/
/src/C/
/src/util/html/
i.e. the main project files are at the root directory and the header and source files distributed into sub folders.
a.h and b.h can be found in debug build but not found in release build.
Yet the .mak file contains:
....
INCDIRS := ....
$(ProjectDir)inc/A \
$(ProjectDir)inc/B \
$(ProjectDir)inc/util/html
So even though /inc/util/html is specified as an include directory in the .mak the project cannot find it - but only in release build.
There is no conditional behaviour between debug and relase builds that I can see - the header files are included within the source code irrespective of build configuration. And the above snippet is the only spot in the .mak file wehre the include directories are specified.
So why should there be a difference between the debug builds and release builds?
Any ideas?
Thanks

I am developing a system of build scripts for CMake and have an issue with wanting to have intermediate CMakeLists.txt files appear in the IDE for easier search and edit.
I have a main CMake file that includes a directory that includes several subdirectories for libraries.
CMakeLists.txt
--- SubProjects:
-------CMakeLists.txt
-------ProjectAFolder:
----------CMakeLists.txt
-------ProjectBFolder:
----------CMakeLists.txt
-------ProjectCFolder:
----------CMakeLists.txt
In the SubProjects folder, the CMakeLists.txt is very simple and just includes the subproject folders one after the other:
SET(SUBDIRECTORIES ProjectAFolder
ProjectBFolder
ProjectCFolder )
foreach (subdirectory ${SUBDIRECTORIES})
add_subdirectory(${subdirectory})
endforeach ()
However, when I generate this in XCode or Visual Studio, the IDE does not include the intermediate CMakeLists.txt file anywhere because it does not belong to any individual library or executable target. What is the best way to include this somewhere so it appears in an IDE?
Depends on where you want the file to show up, since it doesn't belong to any target. You can simply add it to any existing target (just as you do with source files) or you can create a new custom target.
add_library(AnyExistingTarget <other source files> SubProjects/CMakeLists.txt)
Or create a custom target:
add_custom_target(MyIntermediateCMakeFiles SubProjects/CMakeLists.txt)
For Visual Studio, you could also use the built-in support for cmake. It will display the source tree in the IDE without any extra work.
I have 3 projects; Project1.Web, Project1.Service and Project1.Common.
Both Project1.Web and Project1.Service have dependencies on Project1.Common.
If I rebuild the solution which contains all 3 projects; all works correctly.
If I change a file in Project1.Web; files are built to Project1.Web\bin - all works correctly.
If if change a file in Project1.Service files are built to Project1.Service\bin\Debug AND some are copied to Project1.Web\bin. The copied file is Project1.Common.dll, but Project1.Web.dll is not built (or copied).
The file modified in Project1.Service is not shared, its just modified to trigger an incremental build of Project1.Service.
Does anyone know why Visual Studio would be copying a build artifact to a a directory that is not part of the incremental build?
Currently this sequence of events leaves Project1.Web is a non-working state as Project1.Service and Project1.Web have dependencies on different versions of the same assembly via a third party assembly. If we decide to make a change to Project1.Service then it has the side-effect of breaking Project1.Web.
I've tried/checked the following:
There are no dependencies between Project1.Web and Project1.Service (either direction).
The file modified in Project1.Service is not shared; and there are no pre/post build events defined.
Executing msbuild on the Project1.Service.csproj project file does not have the same effect.
Denying write/create permission on the bin directory under Project1.Web does not cause the incremental build to fail.
No output is emitted in the detailed or diagnostic msbuild output that references Project1.Web (from within Visual Studio)
Using procmon, I can see that devenv is using mswebprj.dll (C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\mswebprj.dll) - which invokes the copy of the file.
I have a visual C++ project for a DLL and a setup project for it. In the installer i've added the content files of my project.
Is there a way to add a file as a content file depending on if you are compiling debug or release? I want to include boost_date_time-vc100-mt-gd-1_51.dll if I compile under debug and boost_date_time-vc100-mt-1_51.dll if I compile under release.
My additional deps looks like this
Shell32.lib;libzmq.lib;log4cxx.lib;boost_date_time-vc100-mt-gd-1_51.lib;...
Under additional library directories i've added the path to all these .lib files which also contains their respective .dll files
I've tried the following with no success...
Added a Custom build step to run before build that copies the correct dll files to the OutDir and set the Output of this custom build step to be the dll files.
Conditionally include a content file by manually editing the vcxproj file. If configuration was release mode I would set the non-debug version as deployment content and the debug version to false and vice versa for Debug mode. This looked something like this,
<ItemGroup Condition="'$(Configuration)'=='Release'">
<None Include="boost_date_time-vc100-mt-1_51.dll ">
<DeploymentContent>true</DeploymentContent>....
</None></ItemGroup
Neither of these worked however. The second option seemed to always default to debug mode no matter how I built my project.
When you add a dependency, you can add it to one configuration or all configurations:
[This picture is of VS 2012, but 2010 and 2008 look pretty much the same.]
So, you pick the configuration you want to modify at the top-left, then add the library to the additional dependencies. Note that what you add here will be the .lib file associated with a DLL, not the dll itself (the compiler will make the executable depend on the DLL because you link with its .lib file).
i've the following in the custom build property of every header file that uses Q_OBJECT:
Command Line: $(THIRDPARTY_DIR)\qt\4.7.0\win32-vc10\bin\moc.exe $(InputFileName) -o moc\$(ConfigurationName)\moc_$(InputName).cpp
Description: ################### moc'ing $(InputFileName)
Outputs: moc\$(ConfigurationName)\moc_$(InputName).cpp
This generates the necessary moc files. I now want to ask visual studio to compile and link these too, to my other source files. Presently i'm using
#include "moc\{Release OR Debug}\moc_Whatever.cpp"# statements in any of the files to force compilation and linking. Evidently i have to keep changing my #include according to debug or release build (i cannot discard $(ConfiguarationName) during moc file generation above for reasons). Plus i dont like the idea of writing this #include in the source files just for the purposes of compilation and linking.
Is there any build step in properties anywhere where i can mention what files will be generated in future and to compile and link them when they are available (VS2005)?
(i cannot use QtPlugin right now)
You simply add those files to the project, my project structure usually looks like this (in Visual Studio Solution Explorer):
Solution
|
+- Project1
|
+- Generated Files
+- Header Files
+- Source Files
In Generated Files, I include References to both, the Debug and the Release moc_xxx.cpp and qrc_xxx.cpp files. For the Debug files, you need to set "Exclude from Build" to true for the Release references and vice versa.
That's pretty much the same what the plugin does.
I have a big C++ project and I need to do many steps in the building phase because I am building an application that is compatible with both 64 and 32, I have three projects:
proj1,Porj2,Proj3
and I need to do the following:
Exclude a cpp File from proj1 (32bit version)
Include a cpp file to proj1 (64bit version)
build proj1
build proj2
Execute output of proj2
Exclude a cpp File from proj3 (32bit version)
Include a cpp file to proj3 (64bit version)
Build proj3
Rename the exe that was built from proj3
Exclude a cpp File from proj1 (64bit version)
Include a cpp file to proj1 (32bit version)
still there are some other steps ... I was doing that manually and its frustrating, I found the I need to use MSBUILD but is it used for building native code ? and how can I perfrom these tasks ?
-Excluding and Including cpp files into projects
-Building proj
In Visual Studio 2010 and later, C++ projects use MSBuild.
Rather than excluding or including files based on the configuration, it would be simpler to use a preprocessor directive to conditionally compile the contents of the file. E.g., wrap the entire contents of the file in:
#ifdef MY_32BIT_BUILD_MACRO
// Source file contents here
#endif
And likewise with a macro for 64-bit builds. When using Visual C++, you can use the _M_IX86 and _M_X64 predefined macros to detect whether you are compiling for x86 or x64, respectively.
Alternatively, you could add a Condition property to the ClCompile item for the particular source file in the project file, and have it only included in the build when certain properties are set. I think that conditional compilation within the source file is a better option, though, unless you have complex rules that you need to use to determine whether to include a file or not.
In your solution, you can set project dependencies to ensure that one project is built before another. Right-click the solution, select Properties, and browse to Common Properties -> Project Dependencies. Dependencies can also be specified in a project file.
You can execute the output of a build by using a post-build task. Right-click the project, select Properties, and browse to Configuration Properties -> Build Events. The Post-Build event can be used to execute a command when the build has completed.
Rather than renaming an executable after build, it's easier to just have the build produce an executable with the right name. In the Project properties, under Configuration Properties -> General, the Target Name property can be used to set the name of the primary build output.
