Hi,
I use the following command to build ffmpeg:
./configure --cc=/opt/intel/bin/icc --enable-version3 --enable-asm
--enable-avfilter --disable-static --enable-shared --enable-gpl
--enable-nonfree --prefix=/usr/local/ --extra-cflags='-I/usr/local/include
--extra-ldflags='-L/usr/local/lib --enable-stripping
make
But I fail to compile ffmpeg, and error message is shown as below:
icc: command line warning #10121: overriding '-std=gnu99' with '-std=c99'
libavutil/cpu.c(48): error: identifier "ATOMIC_VAR_INIT" is undefined

Why?
Thanks

Andrew
