I'm trying to build the sdk and builder all four projects in one but I'm getting this in /wex/src/gleasy.cpp. which says
error: ‘glXGetProcAddress’ was not declared in this scope
glWindowPos2f = (PFNGLWINDOWPOS2FPROC)glXGetProcAddress((const GLubyte*)"glWindowPos2f");
^
wex/src/CMakeFiles/wex.dir/build.make:380: recipe for target 'wex/src/CMakeFiles/wex.dir/gleasy.cpp.o' failed
Please suggest how can I fix it.
