Re: adding libraries to L4/fiasco & L4re

Hi,

Porting a library can be as simple as just recompiling the code, or a
whole lot harder. It really depends on the library. Have a look at the
libpng port, and also the openssl port that was posted in this list a
while back.

We have ported several low level libraries from Linux (with kernel
dependencies) whereby we replaced the IOCTL's with IPC between a server
(representing the Linux kernel dependency) and the library for instance.
We also ported video streaming libraries without much change at all.

I believe porting the basic image processing aspects of OpenCV should be
relatively easy. Reading from a camera, openGL, cuda, etc. will be
harder since you will have to build a support infrastructure on L4 for
that. 

I would suggest starting with some of the basic core functionalities to
see what is involved...


Best regards,
Johan
