About cross-compile Qtopia Core-4.3.0beta and OpenGL module
Message 1 in thread
Hi,
i am studying software developing of embedded OpenGL, so i download your opensoure Qtopia Core-4.3.0beta for my study.
now, I have cross-compiled Qtopia Core-4.3.0beta for my ARM PXA270 board. my compiler is armv4l, version 2.95.2 20000516 release. but I found that the module 'src/opengl' have not been compiled. so I enter 'src/opengl' to compile it then, but the compiling process crash when some errors occored, following is message:

------------------------------------
it seems that some header files are missed needed by the module. and then I read the document 'http://doc.trolltech.com/4.2/qtopiacore-opengl.html', so I download the gl header file from "http://www.khronos.org/egl/";, but compiling errors still exist.
what's wrong? which website can I download the missing files?
how can i cross-compile the opengl module and the opengl example?
please help me.
thanks in millions!
