The top-level meson.build file adds WEBRTC_ARCH_MIPS_FAMILY to
arch_cflags for mips architectures, which causes the following error:
[1/306] Compiling C++ object webrtc/rtc_base/liblibbase.a.p/synchronization_yield.cc.o
FAILED: webrtc/rtc_base/liblibbase.a.p/synchronization_yield.cc.o
c++ [...] -DWEBRTC_THREAD_RR WEBRTC_ARCH_MIPS_FAMILY -MD [...] ../webrtc/rtc_base/synchronization/yield.cc
c++: warning: WEBRTC_ARCH_MIPS_FAMILY: linker input file unused because linking not done
c++: error: WEBRTC_ARCH_MIPS_FAMILY: linker input file not found: No such file or directory
It is supposed to be "-DWEBRTC_ARCH_MIPS_FAMILY". But, that macro is
already defined in arch.h when building for mips:
[30/306] Compiling C++ object webrtc/system_wrappers/libsystem_wrappers.a.p/source_cpu_features.cc.o

<command-line>: note: this is the location of the previous definition
Drop the broken, unnecessary argument from cflags.

About
This is meant to be a more Linux packaging friendly copy of the AudioProcessing module from the WebRTC project. The ideal case is that we make no changes to the code to make tracking upstream code easy.
This package currently only includes the AudioProcessing bits, but I am very open to collaborating with other projects that wish to distribute other bits of the code and hopefully eventually have a single point of packaging all the WebRTC code to help people reuse the code and avoid keeping private copies in several different projects.
Building
This project uses the Meson build system. The quickest way to build is:
# Initialise into the build/ directory, for a prefixed install into the
# install/ directory
meson . build -Dprefix=$PWD/install
# Run the actual build
ninja -C build
# Install locally
ninja -C build install
# The libraries, headers, and pkg-config files are now in the install/
# directory
Feedback
Patches, suggestions welcome. You can file an issue on our Gitlab repository.
Notes
- It might be nice to try LTO on the library. We build a lot of code as part of the main AudioProcessing module deps, and it's possible that this could provide significant space savings.
