Hi, Thanks for reporting this.
I'll have a look at the problem, in the meantime a rather crude solution to get it going for you might be to comment out the individual extension detection in ./config/GLExt.cmake. Just remove or comment out the line(s) like: "glew_ext_detection(AMD performance_monitor)"
if you would like to help with the debugging you could do the following:
run configure.py with the --debug-config option and when the configuration stops (at the extension detection) interrupt it (press CTRL+C) and have a look into ./_build/gl/ there should be subdirectories containing the files for the last try_compile test (source + makefiles); try to make them manually, it may give some clues why the test fails.

Ok good to know that.

Ok I am investigating this direction. Thank for pointing this folder which is what I wanted to debug.
I should have a problem with different version of GLEW since the simple compilation of has_GL_4_4.cpp with GLEW gives at execution: Inconsistency detected by ld.so: dl-version.c: 224: _dl_check_map_versions: Assertion `needed != ((void *)0)' failed!
Thanks, Alex

I think I have a strange bug not related to oglplus.
When I compile just this (which is similar but simpler to what oglplus does in extensions detection or in has_GL_4_3.cpp)
int main() { GLenum init_result = glewInit(); if(0) throw std::runtime_error("OpenGL/GLEW initialization error."); return 0; }
with
and run it, I get this:
Inconsistency detected by ld.so: dl-version.c: 224: _dl_check_map_versions: Assertion `needed != ((void *)0)' failed!
provide the same error
If I remove the throw exception, then it works! (Or if I compile with juste this # g++ testGLUT.cpp -lglut it works as well which ok since I do not use GL fonctions).
So there should be a problem on Ubuntu 13.10 with GLEW, GL (nvidia driver). Similar bug is describe here http://ubuntuforums.org/showthread.php?t=2183928
If I find somethings, I'll tell you ... alex

thanks for the info
To close to issue:
Finally, I change the the link of libGL.so which was to mesa to point to the libGL of nvidia: sudo ln -s /usr/lib/nvidia-319/libGL.so /usr/lib/x86_64-linux-gnu/ (something should be wrong in the nvidia driver package).
Sorry it was not related to oglplus.
Thanks for this great lib, alex

Thanks. Good to hear that you got it going.
Hi,
I use oglplus for several months and I like it. But on my new linux (ubuntu 13.10) install I have a problem with Gl and extension detection.
1) If I run ./configure.py --no-examples --from-scratch --include-dir=/home/alex/lib/glew-1.10.0/include --library-dir=/home/alex/lib/glew-1.10.0/lib
It finds GL 4.4 but stop at compiling -- Found GL extension: EXT_direct_state_access But glewinfo gives that this extension is ok
2) If I force glew ./configure.py --no-examples --from-scratch --use-glew --include-dir=/home/alex/lib/glew-1.10.0/include --library-dir=/home/alex/lib/glew-1.10.0/lib
It can not detect GL: -- Detecting OpenGL version Could not detect GL version, assuming 3.0 and stop at -- Found GLEW extension: AMD_performance_monitor which is normal since GLEW tell that this extension is missing: GL_AMD_performance_monitor: MISSING
Can I bypass these tests ? Many thanks, Alex PS: On my laptop (Windows 8.1) every thing is ok (ok it not the same hardware, nor OS).
