raspiberry pi pjsip compile error: emmintrin.h no such file or directory

Question

I'm trying to compile PJSIP (version 2.6) on my Raspberry Pi 3 model B.

While running make dep && make, I get this error:

../../webrtc/src/webrtc//system_wrappers/source/cpu_features.cc

                       ^                                                                                                            
compilation terminated.   

How can this be fixed?

Answer 1

I ran into the exact same issue trying to do exactly what you are doing.

I found a few solutions online but was not satisfied with any of them. They all seemed like nasty hacks.

I looked into the configure script and discovered that sse2 is only required for compiling libwebrtc, which I did not need. Thus I simply disabled the compilation of libwebrtc alongside other things that I didn't need:

 ./configure --disable-sdl --disable-ffmpeg --disable-v4l2 --disable-openh264 --disable-libwebrtc

Note that --disable-v4l2 is referencing video4linux2.

After that the compilation completed successfully.

Looks like this was solved in this thread: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=178384
