Unable to build on macOS Sonoma 14.1.1, Apple Silicon M2

[girishadurrel]

I get the following error when I try to build

SDRPlusPlus/source_modules/audio_source/src/main.cpp:11:10: fatal error: 'RtAudio.h' file not found
#include <RtAudio.h>

I followed this guide with few modifications.

brew install cmake volk glew glfw airspy airspyhf hackrf rtl-sdr soapysdr portaudio pandoc pkg-config codec2 brew install rtaudio@5.2.0 (modification from the above reference) $ sudo ln -s /opt/homebrew/include /usr/local/include $ sudo ln -s /opt/homebrew/lib /usr/local/lib git clone https://github.com/AlexandreRouma/SDRPlusPlus.git cd SDRPlusPlus mkdir build && cd build

cmake .. \
  -DOPT_BUILD_AUDIO_SINK=OFF \
  -DOPT_BUILD_BLADERF_SOURCE=OFF \
  -DOPT_BUILD_M17_DECODER=OFF \
  -DOPT_BUILD_NEW_PORTAUDIO_SINK=ON \
  -DOPT_BUILD_PLUTOSDR_SOURCE=OFF \
  -DOPT_BUILD_PORTAUDIO_SINK=ON \
  -DOPT_BUILD_SOAPY_SOURCE=ON \
  -DOPT_BUILD_SDRPLAY_SOURCE=OFF  (modification from the above reference)

make -j$(sysctl -n hw.ncpu) (causes failure)

on /usr/local/include I do see the following

$ ls -l rtaudio*
lrwxr-xr-x  1 girisha  admin  45 Dec  8 21:51 rtaudio -> ../Cellar/rtaudio@5.2.0/5.2.0/include/rtaudio

inside that symlink I do see

ls -l rtaudio/
total 120
-rw-r--r--  1 girisha  admin  48390 Dec  8 21:51 RtAudio.h
-rw-r--r--  1 girisha  admin  11999 Dec  8 21:51 rtaudio_c.h

out of desperation I did the following in /usr/local/include, but didn't help

ln -s ../Cellar/rtaudio@5.2.0/5.2.0/include/rtaudio/RtAudio.h RtAudio.h

Well obviously following some random unofficial build guide doesn't work... Maybe follow the one in the readme instead? https://github.com/AlexandreRouma/SDRPlusPlus#building-on-macos Delete everything and reclone the repo before doing so.

Thank you for your response. I cleaned everything up and then followed the MacOS guide, I am getting the following error now

/Users/girisha/Projects/SDRPlusPlus/source_modules/plutosdr_source/src/main.cpp:8:10: fatal error: 'iio.h' file not found
#include <iio.h>

I tried installing libiio

  $  curl -LJO https://raw.githubusercontent.com/tfcollins/homebrew-formulae/master/libiio.rb
  $  brew install --build-from-source ./libiio.rb

still says the same error

then saw your comment here, and that worked all I did was to add this option in my cmake -DOPT_BUILD_PLUTOSDR_SOURCE=OFF
