I'm getting started with the GLSL. What should i do to resolve this:
error LNK2001: unresolved external symbol _pglLinkProgram
error LNK2001: unresolved external symbol _pglAttachShader
error LNK2001: unresolved external symbol _pglCompileShader
error LNK2001: unresolved external symbol _pglShaderSource

You seem to be using some form of library that wraps GL entrypoints (the entrypoints you list are not direct GL entrypoints).
This library (GLEE ?) likely is coming with a .lib file that you need to link against.
Coming from the project page of GLEE (my guess, based on a quick googling of who is using the prefix p for GL calls):
Usage examples
To use GLee, include
GLee.h, then simply link to GLee.lib
or alternatively add GLee.c to your
project.
You have to link your program against opengl32.lib, see here.
I recommend you start using GLEW since OpenGL > 1.5 on Windows is a bit of a pain in the ass. This will get you all OpenGL entry points without messing with extension pointers.

I am using mfc class CImageList in my project and using its APIs like Add(), Create() etc. It works fine with vs2010.
Now, I am upgrading the project to vs2012. It compiles and links fine for 32 bit platform, however throws below linking errors for 64 bit.
File1.obj : error LNK2019: unresolved external symbol imp_ImageList_ReplaceIcon referenced in function "public: int __cdecl CImageList::Add(struct HICON *)"
File2.obj : error LNK2019: unresolved external symbol __imp_ImageList_AddMasked referenced in function "public: int __cdecl CImageList::Add(class CBitmap *,unsigned long)"
Similarly, below error is thrown for calling CBitmap api.
File2.obj : error LNK2019: unresolved external symbol __imp_CreateMappedBitmap referenced in function "public: int __cdecl CBitmap::LoadMappedBitmap(unsigned int,unsigned int,struct _COLORMAP *,int)"
It seems that the libraries having these implementations might have been changed. However, I could not find any clue on how to resolve them.
Finally figured out the reason for this error.
ImageList_ReplaceIcon & CreateMappedBitmap symbols are present in comctl32.lib.
There was an older version comctl32.lib present in a path which was included in Additional Include Directories of my project settings.
So, instead of picking this lib from Microsoft SDK folder, the linker was picking from this directory and hence causing problems.
I am getting the following error during linking c++ code with MS VC 6:

Please suggest the possible solution approach.
I think there is a problem of the properties of the project that are dependent on each other.
Probably change the property would fix the problem.
See here /NODEFAULTLIB (Ignore Libraries) and change the property according to your requirment.
Summary: Is there any tiny example on how to build the Win32 C++ console application that uses the libgit2 library (sources available at GitHub)?
I have followed the readme and the wiki on how to build the library on Windows using the CMake, and it worked smoothly (only a single unit-test error).
Now, I want to build a simple console application that uses the library -- using Microsoft Visual Studio C++ 2010 (the.vcxproj and the.sln). I have found the general.c code in the libgit2 examples, and I would like to do the same from my C++ application. No success -- I feel really stupid today...
I have noticed there is libqgit2 for C++ and Qt. Is there anything similar for pure C++? Or is there a way to use the C library from C++ application?
Update: I have renamed the general.c to general.cpp, added the libgit2 include path to the project and the path to the .lib files, changed the #include <stdio.h> to #include <cstdio>, and compiled. The following link errors appear:
1>------ Build started: Project: libgit2_general, Configuration: Debug Win32 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
This strongly suggests a calling convention mismatch to me. libgit2 uses __stdcall by default, for a number of reasons, while Visual Studio defaults to creating projects that use the __cdecl calling convention. While your program can use either calling convention and successfully call libgit2 using a different one, the easiest solution is probably just to use the same calling convention for both.
When you configure libgit2, you can turn off the STDCALL flag, which will cause it to emit a library built with __cdecl calling conventions:
cmake %PATH_TO_LIBGIT2_SOURCE% -DTHREADSAFE=ON -DSTDCALL=OFF
cmake --build .
It's a little surprising if you generated the project from CMake, bit it could be that you're not linking to libgit2.lib. Make sure you have git2.dll in Project Properties -> Configuration Properties -> Linker -> Input -> Additional Dependencies.
I've been going at this problem for almost a week now and I still have 700+ errors. Definitely need all your help! Thanks.
Problem: Need to use
Cocos2dx for Windows Phone 8
in my C++/DirectX Visual Studio 2012 project that also uses C#/XAML UI.
Given: Cocos2dx-wp8 as an Application .exe project downloaded from http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Download
Solution:
Open my C#/XAML/DirectX Game1 solution .sln project in Visual Studio 2012.
Right click on solution in Solution Explorer. Add --> Existing Project...
Selected: \cocos2dx-0.13.0-wp8-0.8\HelloWorld\cocos2d.vcxproj and clicked open
Renamed the HelloWorld project to something else like "Cocos2dxWp8" and delete the HelloWorld Classes folder and all the Assets you don't want (like the squirrels and background images)

From here, it builds successfully!
It outputs a .dll file but no .lib file, so...
In CCPlatformMacros.h, I enabled exporting classes to dll:
#define CC_DLL __declspec(dllexport)
Yah, .lib is being written to then...

Sorry for the long post, but I hope that's enough details to get this question going. Thanks.
I created a new dynamic library project, then copied over the files. I got the .dll and .lib built, but didn't work for an ARM CPU build target (used for devices). Also, the setup for the Cocos2dx director and scene layer doesn't seem to work well with an existing C#/XAML with DirectX project that renders onto a DrawingSurfaceBackgroundGrid control. So at the end, I didn't end up using Cocos2dx in my mixed project setup.
If anyone else got better suggestions, please let me know. Thanks.
ON TOPIC:
Perhaps you did not properly set project dependencies inside your SLN ?
I got Cocos2d to partially work with XAML+D3d Interop, but because calls go back and forward from the XAMLComponent DLL to the Cocos2d DLL, it seems to be messing up pointers and memory.
Right now I tried to move all Cocos2D source files to my D3Dcomponent project, but something is terribly wrong, and I get a weird kernelbase.dll first chance exception.
OFF TOPIC:
I was also trying to put a game done over cocos2d-x on an XAML+D3D Interop project, and used the template that comes with Visual Studio 2012. However, only a smudgy background was displayed. I was using DrawingSurfaceBackgroundGrid, and found out later that on Windows Phone 8, it has some issues related to Z-order. I ended up replacing it with DrawingSurface.
I've built ACE.dll and ACE.lib of the ACE library. But when I link it to my program, I get several errors like
Error 2 error LNK2019: unresolved

Error 3 error LNK2001: unresolved
external symbol "void * __cdecl

I've set include paths,lib paths, lib dependencies etc etc. I dont know what I'm missing :(
The linker is unable to find a definition for ACE_OS::memcpy. Check the documentation and see if you need to provide a suitable definition or not (or if there is one in the sample, if any samples are present at all).
This could also be because you've not defined a platform specific macro that would enable the default definition of this function. Please check the readme.
