Hello everybody !
I recently downloaded qt-4.6.2 and tryied to compile it with support for phonon and openvg, but I'm getting this error:

I guess the error is related with EGL/egl.h not found, in linux the same error risses. I've tryied downloading some libs from Khronos but it just lead to more errors. What should I do to build qt with support for openvg and phonon ? Because it seems impossible to just download de qt-src and compile them with success.
Any sugestion ?
