I get this error when compiling a program:
[Linker error] undefined reference to `wxGLCanvas::wxGLCanvas(wxWindow*, int, wxPoint const&, wxSize const&, long, wxString const&, int*, wxPalette const&)'
can somebosy help me, thank in advanced. | 2. Re: Working with wxGLCanvas #4625 Posted by: upCASE 2004-06-25 17:03:12 | Hi!
For version 2.5.1 you'll have to link libwxmsw25_gl.a in.
Are you sure that you compiled your wxWidgets library with OpenGl support? It is turned off by default...

Re: Working with wxGLCanvas #4626 Posted by: 2004-06-25 18:37:02 | I'm working with Dev++ 4.9.8.0 and wxWindows package 2.4.2. I have assigned wxUSE_GLCANVAS=1 in both files: wx/setup.h and /wx/msw/setup.h. The proyect options for linker are set to:
-Wl,--subsystem,windows -mwindows -lwxmsw -lstdc++ -lgcc -lodbc32 -lwsock32 -lwinspool -lwinmm -lshell32 -lcomctl32 -lctl3d32 -ladvapi32 -lopengl32 -lglu32 -lole32 -loleaut32 -luuid
The error persists.

Ok, so you set wxUSE_GLCANVAS=1. Did you only set it, or was it set when you compiled the library?
Problem is: Just setting wxUSE_GLCANVAS to 1 will make the errors about not finding the wxGLCanvas class go away, but the object files which implement the class will be missing in the library.
Two pssible ways:
1. Set wxUSE_GLCANVAS=1 and recompile the library. Hopefully you didn't do a "make clean" :)
2. Set wxUSE_GLCANVAS=1 and compile only the needed files for OpenGL (I suppose glcanvas.cpp is the only file you need). Either add glcanvas.cpp/glcanvas.o to your project or use "ar" and add it to the library.
