Problem using wxGLcanvas with Dev-C++

Jardel · Post by **Jardel** » Fri Oct 22, 2004 11:03 am

When I want to compile the cube example of wxWindows and OpenGL I've this error :

[Linker error] undefined reference to `wxGLCanvas::sm_eventTable'
[Linker error] undefined reference to `wxGLCanvas::wxGLCanvas(wxWindow*, wxGLCanvas const*, int, wxPoint const&, wxSize const&, long, wxString const&, int*, wxPalette const&)'
etc...

I've configure Dev-C++ 4.9.9.0 to use wxWindows but when I use wxGLCanvas I've this error all the time.

-> I've see a post about this problem at http://forums.wxwidgets.org/viewtopic.php?t=31
but I can't know how to do to rebuild jpg, png, zlib, etc...
with Dev-C++

Help me please.

I guess you have to include the libs that might end with the letters "gl" like libwxmsw25_gl.a and libwxmsw25_ogl.a I'm not sure which version of wx your are using, let us know which dev-pak you are using.

The OpenGL part of wx is not compiled in by default. You will need to download the wx source and compile it yourself.

To be a bit more specific than geon, in the setup.h file for your wxWidgets libraries, there is a constant called wxUSE_GLCANVAS which defaults to 0. Set it to 1, rebuild the wx libs and I believe that should fix the problem.

How does one rebuild the wx libs in DevC++. I used the devpack so i never had to compile.

I downloaded the source now and tried to make a DevC++ project from the wxWindows.dsw, but i have no luck compiling it. It runs into compiler errors immediately. I also i dont know how to make DevC++ compile wxWindows as a series of libs as opposed to a whole exe...

Any help? Even better, does anyone have precompiled libs with glCanvas enabled? I have to say this is most annoying...

You will need those files:
rm.com
cp.com
mv.com

Add them to the "bin" directory of Dev-C++.

In the file commctrl.h you might need to set this #if to 1;

#if 1
#define _WIN32_IE 0x0300
#endif

Set GL_CANVAS to true in this file:
include\wx\msw\setup.h

Paste this into a *.bat file in the base-directory of wx;

Code: Select all

SET MINGWDIR=c:\dev-cpp

PATH=%MINGWDIR%\bin;%PATH%
set BISON_SIMPLE=%MINGWDIR%\share\bison.simple
set BISON_HAIRY=%MINGWDIR%\share\bison.hairy

cd build\msw
make -f makefile.gcc BUILD=clean USE_OPENGL=1 DEBUG_FLAG=0 DEBUG_INFO=0

Run the *.bat file. Wait for 20 min.

I found this link:

(but it didn't seem to work.)
