Embedded X

[Amit]

I got stuck again while porting X11/GTK+ on OMAP.
I'm not sure whether it is the right forum for these questions or not
but these questions are directly or indirectly associated with Mesa/GL
libraries.

Dependency chart is like this ...
GTK+ needs cairo-pdf and cairo-ps backend
cairo-pdf needs glitz installed
while compiling glitz, it looks for GL libraries(libGL) while I have
only GLES libraries meant for OMAP.
I tried cross-compiling MESA for GL libraries but it gave me a
compilation error again. This time it was trying to run the previously
compiled executable for host(arm) on build(x86) platform.

Any help on resolving this issue would be great.

Thanks for your concern.

Regards
Amit Pundir
