#22 GLWXDriver2D building
I build CS (svn revision 40279) on x86 32bits linux platform (MAGEIA 5), using gcc-c++ (4.9.2) and libwxgtku3.0-devel (3.0.2). GLWXDriver2D's build crashes with the following error message:
C++ ./out/linuxx86/optimize/plugins/video/canvas/wxgl/GLWXDriver2D.o
...
In file included from /usr/include/wx-3.0/wx/gtk/glcanvas.h:14:0,

XVisualInfo m_vi;
...
Analysing the glx11.h file, I find the following declaration in the public area of the class "WXDLLIMPEXP_GL wxGLCanvasX11 : public wxGLCanvasBase:"
// get the GLXFBConfig/XVisualInfo we use
GLXFBConfig GetGLXFBConfig() const { return m_fbc; }
XVisualInfo GetXVisualInfo() const { return m_vi; }
so I apply the following patch to GLWXDriver2D.cpp :

Report (CS_REPORTER_SEVERITY_NOTIFY, "Video driver GL/X version %s",
glXIsDirect (dpy, active_GLContext) ? "(direct renderer)" :
And then it works fine.
I submit to you this patch to all intents and purposes.
Fix applied (untested since I'm not in a position to do so presently) as r40280.
