Visual Studio 10中的GLFW链接器错误

Question

I'm having trouble setting up GLFW on Visual Studio 10.0 I was following this guys tutorial. However I am still getting linking errors

1>GLFW.lib(window.obj) : error LNK2005: __glfwClearWindowHints already defined in window.obj
1>GLFW.lib(window.obj) : error LNK2005: __glfwClearInput already defined in window.obj

1>MSVCRTD.lib(cinitexe.obj) : warning LNK4098: defaultlib 'msvcrt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library

I have tried googling the errors but I havent found much help. I have linked opengl32/lib and glu32.lib in the linker settings. I have also linked the appropriate folders for include and lib. I downloaded and linked both the win32 binaries and the original zip from the GLFW site.

code

Any help is appreciated.

That tutorial is kinda outdated (posted 27 April 2005). You probably added some source files twice to two different projects, thus the complaints about already existing definitions of symbols.

It seems that GLFW 2.7.x does not include MSVC makefile scripts for automatically build everything you need, but if its an option to switch to the latest GLFW 3.0 you could make your life easier because they support cmake:

• Make sure you have both cmake and git installed.
• From your Git Bash run git clone git://glfw.git.sourceforge.net/gitroot/glfw/glfw glfw
• Then open a Visual Studio command prompt and switch to the newly created glfw folder. Create a new sub-folder ( mkdir build ) and switch into this one ( cd build ).
• Now run cmake -G "Visual Studio 10 Win64" .. which generates the project files for compiling GLFW.
• Open that project file and compile everything you need (only the GLFW sub-project is required)
