[Libav-user] Build of ffmpeg library with libx264 support for QNX

[Pavel Vazharov]

Hi,

The big problem.

I made the change and run configure
=================================
# ./configure
Memory fault (core dumped)

Last lines from the config log.

The info is probably not very helpful. I'm not sure. Please, tell me what
other information could be useful in order to debug this issue.
I could attach the whole config.log file. I could post the parameters of my
QNX virtual machine. I could try to debug what is happening if you tell me
how.

Thanks for the help.
