Hi,

 

I had already compiled ffmpeg on a 32bits OS for my Orange Pi RK3399 when it ran the Orange Pi 32 bits Ubuntu without too much trouble, but now that I have Armbian on my 4B, I'd like to compile ffmpeg too.

The issue I have is that gcc is started with bad options (I'm not sure of that, that's what I think I understood):

mktemp -u XXXXXX
ZgAQ9I
test_ld cc
test_cc
BEGIN /tmp/ffconf.efsAigGe/test.c
    1   int main(void){ return 0; }
END /tmp/ffconf.efsAigGe/test.c
gcc -mfpu=neon -c -o /tmp/ffconf.efsAigGe/test.o /tmp/ffconf.efsAigGe/test.c
gcc: error: unrecognized command line option '-mfpu=neon'
C compiler test failed.
poddingue@orangepi4-armbian:~/ffmpeg_sources/FFMpeg-orig$  ./configure
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.

My gcc version is :

gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/aarch64-linux-gnu/8/lto-wrapper

Thread model: posix
gcc version 8.3.0 (Debian 8.3.0-6)

 

My machine is running Armbian buster with Linux 5.4.49-rockchip64Debian 10 buster with Kernel: aarch64 Linux 5.4.49-rockchip64.

Is there anything I could do with configure so that it uses the right options?

 

I have compiled tons of other sources on that machine, but ffmpeg and x264 really don't like it.
 

Thanks.

I am absolutely unqualified to give an answer here but out of curiosity I searched the error and found you may not have to specify an option to use neon?

Thanks, I will have a look at it.

I finally had to

export CFLAGS=

to get the configure script to work.
