sallu.salmankhalid · 06-19-2013, 01:45 AM

Hi I completed my LFS installed wget and dhcp support(network is on dhcp) now I have project in which I have to make an opencv gui application (multithreaded) on Linux From Scratch (dont ask why :-( ) Now I dont have apt-get or dpkg I dont want it. I browsed a little and found the dependencies for opencv

GCC 4.3 or later (already installed in LFS)
CMAKE 2.6 or later
Qt 4.6
pkg-config (already installed)
ffmpeg, libgstreamer, libv4l, libxine, unicap, libdc1394 2.x

Any ideas what should I consult is there any guide that could help me

thanks in advance :-)

I'm not sure what the problem is you have, but here are some pointers that might help:

- OpenVC source-code -> OpenCV (sourceforge)
- OpenVC Installation -> Installation in Linux
- Qt and cmake are part of BLFS.
- Also part of BLFS are: ffmpeg. xine-lib, libgstreamer

I'm quite sure that the sources for the other dependencies can also be found on-line. A quick search for 4vl for example comes up with this: v4l-utils and libv4l
