OpenGL version detection fails on Windows 10, Visual Studio 2015

[deranen]

When configuring oglplu2 I get the following build error during OpenGL version detection:

C:\Program Files (x86)\Windows Kits\8.1\Include\um\GL/gl.h(1162): error C2375: 'glBindTexture': redefinition; different linkage [C:\Users\deranen\Documents\Visual Studio 2015\Projects\oglplu2\gl\CMakeFiles\CMakeTmp\cmTC_db938.vcxproj]
  C:\Users\deranen\Documents\Visual Studio 2015\Projects\oglplu2\third_party\include\GL/glcorearb.h(425): note: see declaration of 'glBindTexture'

I had to modify GLVerExt.cmake to output the build error. Ideas?

[matus-chochlik]

Which "GL context" library (GLUT/GLFW/GLFW3/SDL/...) do you use on Windows? Seems that one of them does include a version of GL.h which is not compatible with Khronos' GLcorearb.h. One thing which might help is to use --use-glew when invoking the configure script, or specifying -DFORCE_GL_API_LIB=GLEW to cmake.

[deranen]

I wasn't using any(!). Shouldn't cmake warn me about that before even trying to proceed and find OpenGL version?

Anyways, let's take a step back first. This is actually currently what cmake outputs as I configure it:

See also "C:/Users/deranen/Documents/Visual Studio 2015/Projects/oglplu2/CMakeFiles/CMakeOutput.log".

CMake's own FindGLUT can't seem to find it by itself, even though I have manually set the following variables in CMake:

GLEW_INCLUDE_DIRS = C:/Users/deranen/Programming/glew-1.13.0/include
GLEW_LIBRARIES = C:/Users/deranen/Programming/glew-1.13.0/lib/Release/x64/glew32.lib
GLUT_INCLUDE_DIRS = C:/Users/deranen/Programming/freeglut-3.0.0/include
GLUT_LIBRARIES = C:/Users/deranen/Programming/freeglut-3.0.0/lib/Debug/freeglutd.lib

But this doesn't seem to fix it. I edited config/FindGLUT.cmake since it looked like there was an error there in how it set the variables. That is how I got all the way to the OpenGL version check step. But maybe we should first try to find the issue with config/FindGLUT.cmake and correct that?

I could try to make a PR with my change to config/FindGLUT.cmake so that you can take a look at the change.

[deranen]

I made a PR #9.

[matus-chochlik]

LGTM and it does not break anything on Linux. Merged.

[deranen]

Great!

As of latest, with the following symbols set:

GLEW_INCLUDE_DIRS = C:/Users/deranen/Programming/glew-1.13.0/include
GLEW_LIBRARIES = C:/Users/deranen/Programming/glew-1.13.0/lib/Release/x64/glew32.lib
GLUT_INCLUDE_DIRS = C:/Users/deranen/Programming/freeglut-3.0.0/include
GLUT_LIBRARIES = C:/Users/deranen/Programming/freeglut-3.0.0/lib/Debug/freeglutd.lib

CMake outputs the following:

Note that I still get Could NOT find GLUT (missing: GLUT_glut_LIBRARY GLUT_INCLUDE_DIR) which is output from CMake's own FindGLUT. I guess we can ignore this since later we get Using GLUT for GL context initialization.

Here is the build error from the OpenGL version detection code:

Any idea of what the root of the problem is here?

[matus-chochlik]

The link error with GLEW may be related to static vs. dynamic version of the library. I vaguely remember that on one of the Windows machines where I tested the original oglplus I had to use the glew32s.lib file.

[deranen]

Unfortunately, that didn't work.

[matus-chochlik]

Hmm, it actually seems that glut32.lib is not on the list of libs to link to.

[matus-chochlik]

Could you try adding message("${CONFIG_REQUIRED_LIBRARIES}") toGLVerExt.cmakeline72` and see what that prints out?

[deranen]

Here is the output:

;;C:/Users/deranen/Programming/freeglut-3.0.0/lib/Debug/freeglut_staticd.lib

As you can see I am using freeglut. Is that ok?

[matus-chochlik]

There is no problem with freeglut. However glew32.lib should be listed there. Could you try to trace how the following variables (OPENGL_LIBRARIES, OGLPLUS_GL_LIBRARIES, CONFIG_REQUIRED_LIBRARIES) are set in the cmake files ?

[deranen]

The following line in ConfigGL.cmake sets OGLPLUS_GL_LIBRARIES:

set(OGLPLUS_GL_LIBRARIES ${GLEW_LIBRARIES} ${OPENGL_LIBRARIES})

What's interesting is that ${GLEW_LIBRARIES} is empty, and ${OPENGL_LIBRARIES} contains the glut32.lib library. So when ${GLEW_LIBRARIES} is queried in GLVerExt.cmake it is empty.

I'll continue investigating why ${GLEW_LIBRARIES} is empty.

EDIT: @matus-chochlik Never mind what I just said, ${GLEW_LIBRARIES} is set at this point.

[deranen]

Ugh, I messed up and had by mistake commented out line 45 in GLVerExt.cmake: set(CONFIG_REQUIRED_LIBRARIES "${OGLPLUS_GL_LIBRARIES}").

Yep, that happened.

However, I still get the same build error: has_GL_4_5.obj : error LNK2019: unresolved external symbol __imp_glewInit referenced in function "public: __cdecl oglplus::api_initializer::api_initializer(int,int)" (??0api_initializer@oglplus@@QEAA@HH@Z) [C:\Users\deranen\Documents\Visual Studio 2015\Projects\oglplu2\gl\CMakeFiles\CMakeTmp\cmTC_9275d.vcxproj]

I've verified that the library is included to the compiler.

[matus-chochlik]

Hmm, I still think that trying to link with the static version of GLEW might help, but you also need to define the GLEW_STATIC preprocessor symbol, for that to work. See http://glew.sourceforge.net/install.html

[deranen]

How do I feed that into the try_run cmake function? Or do I set it somewhere else? cmake can be confusing!

[matus-chochlik]

IMO as one of the values after the COMPILE_DEFINITIONS parameter of try_run, should work.

[deranen]

I finally got it working! This is what I had to add after COMPILE_DEFINITIONS: "-DGLEW_STATIC -DFREEGLUT_STATIC "

Something about the fact that you need static versions of these libraries in Windows should probably be mentioned in the README. Also, can these defines be added automatically if on Windows? I'd hate for someone to have to go through the same problems I had.

Thanks for the help!

[matus-chochlik]

Thanks for sticking with it! I will have to reinstall windows on one of my machines again and try to fix this so that it works automatically.

[ghost]

Hello. oglplu2 works on windows? Give me build instruction on windows.

[matus-chochlik]

There is a branch called backported-develop where most of the things do build with MSVC 2015 update 1 (the rest of the issues are slowly being fixed).

My working setup: WIndows 10 + MSVC 15 Update 1 + GLFW3 and GLEW (both installed directly into MSVC's include and lib dirs) + cmake and ctest (for windows, added to PATH) + cygwin with python and git.

• Git-clone oglplu2
• Checkout branch backported-develop.
• run the configure.py script or do mkdir _build && cd _build && cmake -G "Visual Studio 14" ..
• Open the generated solution and build it

[ghost]

I tried all options in main version, but no possible... span.h, GSL, etc. Linux only feature...

[ghost]

I try in Visual Studio 2017...

[matus-chochlik]

Hi, let me know how that goes. Unfortunately at the moment MSVC still isn't supported since I don't have any windows development machine.
