I am trying to use the gloox library (C++) to create a Windows XMPP application. It seems simple enough, except I don't know how to import gloox into Visual Studio 2010 so I can include it in my application project.
I've looked at the instructions provided in the read-me (shown below), but when I try to compile the library, I get this error:
Cannot open source file: 'src\tlsgnutlsserver.cpp': No such file or directory
Instructions provided in the read-me file:
Building gloox on MSVC++
use the included project file or create your own
adjust include + library paths if necessary
to receive any debug output you should use the LogSink facilities (this is not win32-specific)
build
Does anyone have experience using Gloox with VS10? If yes, can you please help me out? Thanks!
I assume you're using the official 1.0 tarball? I had the same problem (missing source file) and had to acquire the source from SVN instead. I used the 1.0 branch.
I encountered a few other build problems, namely
the release build configuration was set to build an Application (.exe) instead of Dynamic library (.dll) (Project->Properties->General->Configuration Type)
I needed to add DLL_EXPORT to the preprocessor definitions (Project->Properties->Configuration Properties->C/C++ ->Properties->Preprocessor)
src\atomicrefcount.cpp needed to be added to the project's source files. (Project->Add Existing Item)
This worked for me in express editions of both VC++ 2010 and VC++ 2008.
Hopefully it helps you as well.

I am using Visual Studio 2017 on Windows 10.
I have added correctly the include directory and the library directory.
I created it as a console application.
I added the #include "stdafx.h" at the start of the main file.
This are the errors that Microsoft Visual Studio show to me:
Can you help me solve this?
There is anything that I should know for making this work correctly?
Thank you to everyone,

Those errors are as has been noted indeed linker errors. If the compiler does not complain that means you have you include paths set up correctly, so you have won half the battle.
For linker errors you can try these things:
Make sure your *.lib files are built for the same target you're building your own project for.
If you use NuGet then you can look in the /packages folder of your project. Browse down to /packages/[package name]/build/native/lib/[architecture]/. There you will find folders like v120 or v140. For Visual Studio 2017 they need to be v141. If they are missing then you can tell VS to target the older platform (project properties -> general -> platform toolset)
If you've built the libraries yourself then maybe you did that similarly targeting a different platform? Try building the OpenCV library again and make sure the target is set to v141 (or whatever you want to use).
Make sure the linker can find your libraries. If you're using NuGet this step isn't necessary but if you built the library yourself or if you downloaded a prebuilt one then go into project settings and:
Go to VC++ directories -> Library Directories, edit that value and make sure the folder that contains the *.lib files is in there.
Go to Linker -> Input -> Additional Dependencies, edit it and put in all the *.lib files. Just their names, not full paths. In your case you'd just put opencv_world331d.lib there.
Be aware that any of the above settings need to be done for each configuration. Usually there is a x86 and x64 architecture combined with debug or release configuration. If you switch any of these you'd have to check the above steps again. This is a bit of a hassle so you're better off defining a property sheet once which you can then reuse every time you do a OpenCV project. There was a tutorial for this in OpenCV 2.4's documentation, and some people have made premade ones.
I have MFC Dialogue based applications written in VC++6.0. Due to my work environment requirements I need to upgrade to Visual Studio 2010. I don't need to add any new feature, just compile with the upgraded visual studio.
Can any guide me on this?
What are all the primary requirements and how to start it?
Just open the project/solution in VS-2010. Convert it and compile.
You might get some compiler warnings/errors depending on your code, because the new compiler is more precise.
But most conversions lead just to a view warnings, like security stuff and others and should work directly.
From the VC++ team blog and Visual Studio 2010 C++ Project Upgrade Guide:
With Visual Studio 2010, C++ build system moved from the VCBuild based system to the MSBuild based build system.
The C++ project system is also built on top of the MSBuild build system.
There are some limitations, known issues or by design changes that you may run into during the upgrade process.
VS2010 supports upgrading from VC6, VS2002, VS2003, VS2005 and VS2008.
As in previous versions of Visual Studio, upgrade can be done either through IDE conversion wizards or from the command line (Devenv.exe /upgrade).
Here are the recommendations for upgrading your applications:
1) Set up the upgrade environment the same as your build environment
The upgrade process will try to load files and evaluate values during upgrade. If your projects use values that are not defined by the project files themselves, for example, values defined by environment variables, it is required that these environment variables are set up before doing the upgrade. Without these environment variables properly set up, you may get conversion warnings or errors caused by unevaluated values.
2) Make sure you have the required platforms installed before doing upgrade
Converting a project on a machine without all the available platforms for the project will result in a conversion error. For example, if you try to convert a project with Itanium Platform on Visual Studio Professional SKU, which does not support the Itanium platform, you will see a conversion error like the following:
Failed to upgrade 'Debug|<Itanium>'. Please make sure you have the corresponding platform installed under
'%vctargetspath%\platforms\Itanium'. Cannot load the project due to a corrupt project file. The following error
has occurred during XML parsing:
File: D:\Sample\ConsoleApp\ConsoleApp.vcproj
Line: 28
Column: 5
Error Message:
System error: -2147154677.
The file 'D:\Sample\ConsoleApp\ConsoleApp.vcproj' has failed to load.
This is by design as the conversion needs to evaluate the properties in the missing platforms to do a successful conversion. You can verify which platforms are installed on your machine by looking in the following directories: %ProgramFiles%\MSBuild\Microsoft.cpp\V4.0\Platforms (or %ProgramFiles(x86)%\MSBuild\Microsoft.cpp\V4.0\Platforms on x64 machine) for the Platforms installed on the machine.
3) Use native Multi-Targeting to build against VS2008 toolset first if possible
In VS 2010, Native multi-targeting have been added which allows you to build against the Visual Studio 2008 toolset from within the VS2010 IDE using the new MSBuild-based project system. I recommend you to take advantage of this feature by using VS2010 to build against VS2008 toolset first when upgrading. This can help isolate any project system/build system related issues from the tools issues that you may run into after upgrade. This will make the move to the VS2010 toolset much smoother.
Upon upgrade, the property sheet files (.vsprops) are converted to their new format (.props). Likewise, project files (.vcproj) are converted to their new format (.vcxproj). Note, the new project files are generated alongside the old project files. A new file type (.filter.vcxproj) is also generated during conversion. The filter files contain the information that is used to display folders in the solution explorer. This filter information was originally part of the project file. This change was necessary because MSBuild requests a rebuild whenever the project files changes. By storing filter information in a separate file, the filter can be changed without triggering a rebuild of the entire project.
Note: Upgrade process will not convert the .user file. As a result, your debugging and deployment settings will not be preserved after conversion.
In VS2010, a new command line upgrade tool, VCUpgrade.exe is introduced. This command line tool is suitable for upgrading applications with only one project as it cannot take in solution file as input and parse solution information into project files. VCUpgrade.exe is located at: $(VSInstallDir)\common7\Tools directory. This tool will also be shipped in the next release of WinSDK so that the users can do command line upgrade of the project files shipped in WinSDK without Visual Studio IDE.
I am trying to build a project from the following Source Code (it accompanies a book I am currently reading). Unfortunately, visual studio can not run a library with the name "cyclone_d.lib". I believe this is because visual studio simply can not locate the file. I have spent several hours trying to fix this problem by changing the settings in the linker and project, for example adding Additional Directories, but I have not been able to get any results.
Please let me know how I can fix this problem and compile the code.
Thank You!
Your link to source points only to some Unix-style source files but no VS project files. So I can only guess and give general help.
A VS solution contains one or more projects. Each project has a build target, in most cases a EXE, DLL, or static library LIB. When you have a solution that includes an project with an EXE build target set the option "Set as StartUp Project" at that project in the solution tree.
If you don't have an EXE change your project setup to create a Win32 executable instead a library. For this task the most simple approach is creating a new project (Win32 Console Application or Win32 Project) and add all the source files.
I want to develop gpu computing algorithms using CUDA. I'm using Visual Studio 2010 Ultimate edition. After I install all the computing tools and SDK with samples, I see under project types "NVIDIA->CUDA->CUDA 4.0 Runtime" choice to start a CUDA project.
The problem is that I can't include source files located at ProgramData/NVIDIA Corporation/NVIDIA GPU Computing SDK 4.0/Common/inc to work with samples, use header files under GL directory etc. I'm trying to include them using "Additional Include Directories". I'm adding the full path, but it doesn't work. Visual Studio doesn't see those files.
How can I use these files? What should I type in to get these files?
I compiled cutil project under common directory, it solved some error problems while trying to compile samples but it made no use for the issue I stated above.
These are the steps I took to install CUDA into VS2010.
Create a normal project of your choice. (e.g. win32)
Right click the project and choose Build Customizations. If you have installed the tools and SDK correctly you should see a CUDA 4.0 target. (If your project becomes corrupt you may also have to replace the existing ExtensionSetting import in your .vcxproj file)
<ImportGroup Label="ExtensionSettings">
<Import Project="$(VCTargetsPath)\BuildCustomizations\CUDA 4.0.props"/>
</ImportGroup>
Your include path should already be setup, if it is not then add $(CUDA_INC_PATH) to your VC++ include directory.
Add cudart.lib to your Linker additional libraries ensuring that $(CudaToolkitLibDir) is added to the paths.
Create a file and give it the .cu file extension. Right click the file, go to properties and select the Item Type as "Cuda C/C++".
Once sthis i complete you should be able to compile Cuda in VS2010. I may have forgetten some steps, you may need to fiddle abit, I will edit this post if I recall tomorrow.
Direct Question: How do I create a simple hello world CUDA project within visual studio 2010?
Background: I've written CUDA kernels. I'm intimately familiar with the .vcproj files from Visual Studio 2005 -- tweaked several by hand. In VS 2005, if I want to build a CUDA kernel, I add a custom build rule and then explicitly define the nvcc call to build the files.
I have migrated to Win 7, and VS 2010 because I really want to try out nSight. I have nSight 1.5 installed. But this is where I'm totally lost. If I proceed as before, nvcc reports that it only supports msvc 8.0 & 9.0. But the website clearly states that it supports VS 2010.
I read somewhere else that I need to have VS 2008 (msvc 9.0) also installed -- my word. Doing so now.
But I'm guessing that at least part of my problems stem from the homegrown custom build tool specifications. Several websites talk about adding a *.rules file to the build, but I've gathered that this is only applicable to VS 2008. Under "Build Customizations" I see CUDA 3.1 and 3.2, but when I add kernels to the project they aren't built. Another website proclaims that the key is three files: Cuda.props Cuda.xml Cuda.targets, but it doesn't say how or where to add these files -- or rather I'll gamble that I just don't understand the notes referenced in the website.
So does anyone know how to create a simple project in VS 2010 which builds a CUDA kernel -- using either the nSight 1.5 setup or the NvCudaRuntimeApi.v3.2.rules file which ships with the CUDA 3.2 RC?
Thanks in advance! I'd offer a bounty, but I only have 65 points total.
CUDA TOOLKIT 4.0 and later
The build customisations file (installed into the Program Files\MSBuild\Microsoft.Cpp\v4.0\BuildCustomizations directory) "teaches" Visual Studio how to compile and link any .cu files in your project into your application. If you chose to skip installing the customisations, or if you installed VS2010 after CUDA, you can add them later by following the instructions in Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.0\extras\visual_studio_integration.
Create a new project using the standard MS wizards (e.g. an empty console project)
Implement your host (serial) code in .c or .cpp files
Add the NVIDIA build customisation (right click on the project, Build customizations, tick the relevant CUDA box)
See note 1 if using CUDA 4.0
Implement your wrappers and kernels in .cu files
If you added .cu files before the build customisations, then you'll need to set the type of the .cu files to CUDA C/C++ (right-click on the file, Properties, set Item Type)
Add the CUDA runtime library (right click on the project and choose Properties, then in Linker -> Input add cudart.lib to the Additional Dependencies)
Then just build your project and the .cu files will be compiled to .obj and added to the link automatically
Incidentally I would advocate avoiding cutil if possible, instead roll your own checking. Cutil is not supported by NVIDIA, it's just used to try to keep the examples in the SDK focussed on the actual program and algorithm design and avoid repeating the same things in every example (e.g. command line parsing). If you write your own then you will have much better control and will know what is happening. For example, the cutilSafeCall wrapper calls exit() if the function fails - a real application (as opposed to a sample) should probably handle the failure more elegantly!
NOTE
For CUDA 4.0 only you may need to apply this fix to the build customisations. This patch fixes the following message:
The result "" of evaluating the value "$(CudaBuildTasksPath)" of the "AssemblyFile" attribute in the element is not valid
This answer applies to CUDA 3.2, from 4.0 onwards CUDA supports the VC 10 compiler directly, see other answers for more information
You need either VS 2008 or the 6.1 Windows SDK installed. That's because NSight 1.5 RC or the CUDA 3.2 SDK use the VC 9 compiler under the hood. I've got this working successfully with 2008 installed and am told it should work with the SDK but haven't tried.
With NSight 1.5 and/or the CUDA 3.2 SDK you shouldn't need to muck with any custom build rules. I've been there and it's painful. With the latest builds all that goes away:
Create your VC++ project.
Add a .CU file to it.
Select the project file in the Solution Explorer.
Open Project | Build Customizations...
Check the "CUDA 3.2 (.targets,
.props)" customization.
Select a .CU file in your project and hit Alt-Enter to show it's properties.
Make sure it's Item Type is set to "CUDA C/C++"
It should just build. Let me know if this helps and if you run into problems as this is from memory.
The good news it getting CUDA working with VS 2010 just got much easier.

BTW: I'll update my blog post.
Another Good tutorial here:
http://www.stevenmarkford.com/installing-nvidia-cuda-with-visual-studio-2010/
if you get an error about '<' note this step (from a previous answer):
If you added .cu files before the build customisations, then you'll need to set the type of the .cu files to CUDA C/C++ (right-click on the file, Properties, set Item Type)
But if you follow their steps, it should work!
