Enabling OpenGL in wxWidgets

Question

I installed the wxWidgets source code, compiled it and am linking the libraries thus obtained with my application code. Now I need to use OpenGL in my wxWidgets application. How do I enable this?

Answer 1

(Assume $(WXWIDGETSROOT) is the root directory of your wxWidgets installation.)

1. Open the file $(WXWIDGETSROOT)\include\wx\msw\setup.h
2. Search and find the option wxUSE_GLCANVAS. Change its value from 0 to 1.
3. Recompile the library.

Answer 2

If you're using configure to build wxWidgets you just need to add --with-opengl to your command line.

Answer 3

For building on Windows with project files:

Assume $(WXWIDGETSROOT) is the root directory of your wxWidgets installation.

1. Open the file $(WXWIDGETSROOT)\include\wx\msw\setup.h
2. Search for the #define for wxUSE_GLCANVAS.
3. Change its value from 0 to 1.
4. Recompile the library.

For building on Linux and other ./configure based platforms:

Just use ./configure --with-opengl
