Error "g++: error: unrecognized command line option '-mfma'" when building latest master on Yocto (Debian 10) linux

[aleh4d]

Describe the bug

I tried to compile latest master sours from repository on Yocto (Debian 10) Linux to get support for WebRTC AEC3 (as describe in https://github.com/pjsip/pjproject/pull/2722)

On 'make dep' step Got Error "g++: error: unrecognized command line option '-mfma'"

Steps to reproduce

steps to reproduce:

wget https://github.com/pjsip/pjproject/archive/refs/heads/master.zip
unzip -a master.zip cd pjproject-master cp pjlib/include/pj/config_site_sample.h pjlib/include/pj/config_site.h ./configure --disable-video --enable-libwebrtc-aec3 make dep

PJSIP version

Your machine probably doesn't support avx2, so try removing/commenting this part in third_party/build/webrtc_aec3/os-auto.mak:

    export WEBRTC_AEC3_SRC += \
    common_audio/resampler/sinc_resampler_avx2.o \
    modules/audio_processing/aec3/adaptive_fir_filter_erl_avx2.o \
    modules/audio_processing/aec3/adaptive_fir_filter_avx2.o \
    modules/audio_processing/aec3/fft_data_avx2.o \
    modules/audio_processing/aec3/matched_filter_avx2.o \
    modules/audio_processing/aec3/vector_math_avx2.o \
    modules/audio_processing/agc2/rnn_vad/vector_math_avx2.o
    WEBRTC_AEC3_OTHER_CFLAGS += -mfma

If it works, then I can create a patch to automatically detect this.

[aleh4d]

Can not find file "third_party/build/webrtc_aec3/os-auto.mak" looks like the file does not exist:

ls -la third_party/build/webrtc_aec3/ total 28 drwxr-xr-x 2 compulab compulab 4096 Jul 15 08:05 . drwxr-xr-x 14 compulab compulab 4096 Jul 15 07:59 .. -rw-r--r-- 1 compulab compulab 7104 Jul 15 08:00 .libwebrtc-aec3-aarch64-unknown-linux-gnu.depend -rw-r--r-- 1 compulab compulab 9141 Jul 13 09:36 Makefile

It is Yocto linux that I am using - it is Debian 10 bases, but Arm64, cant that be the reason? What to try next?

[sauwming]

Sorry, it should be third_party/build/os-auto.mak

[aleh4d]

there is the file: "third_party/build/os-auto.mak.in" so it has "mak.in" extension, right?

[aleh4d]

Thank you for support, commented the lines that you specified in the file is the file: "third_party/build/os-auto.mak.in" now make dep worked only with 2 errors:

../../webrtc/src/webrtc//modules/audio_processing/aec/aec_core_sse2.c:15:10: fatal error: emmintrin.h: No such file or directory

include

      ^~~~~~~~~~~~~

compilation terminated. ../../webrtc/src/webrtc//modules/audio_processing/aec/aec_rdft_sse2.c:13:10: fatal error: emmintrin.h: No such file or directory

include

      ^~~~~~~~~~~~~

does that mean that WebRTC was not found? It will be without echo cancellation because of that?

[sauwming]

Just realised that your machine's architecture is aarch64. So please try the attached patch instead: aconfigure_patch.txt

• Revert the modification in os-auto.mak
• Clean and rebuild PJSIP (i.e. make clean && ./configure && make dep && make)

[aleh4d]

unzipped clean version, applied the patch, then called configure: ./configure --disable-video --enable-libwebrtc-aec3 and still got the following errors on "make dep"

../../webrtc/src/webrtc//modules/audio_processing/aec/aec_core_sse2.c:15:10: fatal error: emmintrin.h: No such file or directory

include

      ^~~~~~~~~~~~~

compilation terminated. ../../webrtc/src/webrtc//modules/audio_processing/aec/aec_rdft_sse2.c:13:10: fatal error: emmintrin.h: No such file or directory

include

      ^~~~~~~~~~~~~

I am compiling with WebRTC for echo cancellation, does that mean that I should download and compile WebRTC first? Need instruction how compile with WebRTC, and whether it needs to download WebRTC separately, or part of it is already included in PJSip project?

[sauwming]

You can try this updated patch: aconfigure_patch2.txt

Alternatively, you can disable WebRTC as mentioned in the other issue #2752.

[aleh4d]

Downloaded fresh copy of master, When applying patch got following error: (so patch was partially applied) result of patch application:

[asesidaa]

I can confirm that manually apply the patch (adding aarch64 checks) can fix the compilation issue on arm64 machines. (At least on mine) Maybe add this patch to master branch?
