I can't reproduce your issue. Look: $ make distclean ; ./configure --cross-prefix=mips-linux-gnu- --arch=mips --target-os=linux --enable-cross-compile --disable-mipsfpu And then: $ make -j1 V=1 2>&1 | tee build.log And then: $ grep "uses soft float" build.log $ grep "filtfmts-test" build.log It gives me nothing. Also I try to find for that filtfmts-test file which your logs say that is using hard-float, and I cannot find it: $ find . -name "filtfmts-test*" $ Regards, Vincent. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
