Hi, I had already compiled ffmpeg on a 32bits OS for my aarch64 machine without too much trouble, but now that I have a 64bits OS, 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. Only do this if you know what cross compiling means. C compiler test failed. My gcc version is : gcc -v Using built-in specs.

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