# building Audacity 3.0.x

# environment
# 2011 Mac Mini, Core i5, 16GB RAM
# macOS 10.13.6
# from previous efforts with other compile work, brew already installed

# pre-reqs

# cmake install
# in the case of brew, 10.13 is no longer supported, but most anything one wants can still be built from source
brew install --build-from-source cmake

#conan install
# a version > 1.33.0 is required, and given the age of 10.13, I figured it best to go just slightly beyond the minimum required
pip3 install -Iv conan==1.34

# audacity source (one of the tracker-free, reporting-free forks)
git clone https://github.com/cookiengineer/audacity.git
cd audacity
mkdir build
cd build

# cmake compile
# for reasons unclear, the linker wanted to link to JACK, but I have no headers for JACK, so the Xcode project was failing in one of the last build stages, so I figured out how to remove the dependency 
cmake -GXcode -Daudacity_use_pa_jack=off -T buildsystem=1 -j 4 ..

# Xcode build (using Xcode 10.1, which is one of the final versions targeting 10.13)
# launch Xcode, then open $GIT_HOME/audacity/build/Audacity.xcodeproj ($GIT_HOME is wherever you keep your git repos, the parent where you ran the ‘git clone’ command)
# in Xcode UI, click the ‘Play’ button
# if all goes well, wait a while, and then the built Audacity will launch all by itself once completed
