Hi,

The thing is that the example I started working on was from the RMA SDK and I took \
the files you told me about from the Helix CVS. So mixing them created a big mess, \
that's the reason why I thought it would be better to re-code everything in the Helix \
SDK, starting from the same example (capture_vframes which was exwlsite in RMA SDK, \
but you know this for sure). Anyway after struggling again with GCC versions and \
Makefiles I finally compiled the example but it doesn't work. The Makefile is the \
same as the one I used with exwlsite (just changed include folders for helix). The \
capture_vframes example crashed because it couldn't retrieve the CLientEngineSelector \
(got a null pointer and tried to ->Select which caused a segfault). So I replaced the \
Select by a Unix select, then a usleep() but it still doesn't work, and I didn't \
change anything else in the example, it's the exact CVS one.  Maybe my problem comes \
from my Makefile, which I took from the RMASDK and modified a bit. I tried to use \
umake and build but it doesn't wotk, all I get when using them is ":No such file or \
directory" even when I just type "build --man" (I checked and everything is \
installed, python and all, I added /build/bin to PATH).

Please give me some light, 
Kouiskas

-----------------------

Adding dev@video.

It should be no problem to run without X. We have done this for
systems like linux/arm on the Zaurus and iPAC/linux.

For a good start take a look at:
    
    video/sitelib/platform/unix/linux_fb_site.cpp and
    video/sitelib/platform/unix/linux_fb_surf.cpp 

Those are frame buffer sites and don't use X.

Let me know how it goes.

--greg.
