[vlc-devel] - cross compile problems

[Yiannis Yiakoumis]

Hey everybody, 

Once again I have problems when cross-compiling vlc for arm. It seems that some libraries do not include specific definitions, and I cannot understand why.
I get a lot of errors. I just post here one case (with file vout_synchro.h), and I hope that if that is fixed, I can go further by myself.

However, in file ./modules/codec/libmpeg2.c file vout_synchro.h is included (which file have all these definitions, in terms of VLC_EXPORT(........).

I don't have any idea what can cause this error and where to search. 
Any idea would be really helpful.

Thanks a lot,
Yiannis
