I downloaded the last version of ffmpeg and tried to configure, here is the report
~/ffmpeg/FFmpeg$ ./configure --enable-cross-compile --arch=arm --cc=qcc
qcc is unable to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[hidden email] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
But i was able to make configure with these flags:
./configure --enable-cross-compile --arch=x86 --cc=ntox86-gcc --target-os=qnx
I'm using machine with x86 architecture, so i changed your configure line a liitle, and changed compiler, because i have been recieved error "qcc is unable to create an executable file.
C compiler test failed."
I dont know what part of configure log u need, so:
install prefix /usr/local
source path .
C compiler ntox86-gcc
host C compiler gcc
host C library glibc
