sudo make install

If this error occurs:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

open the Xcode Preferences → Locations Tab select the version:

git clone <git repository>
cd Rocrail
make -j8 PLATFORM=MACOS ORIGIN=LOCAL fromtar
./makemac.sh ventura-M1

No longer supported; Missing up to date compiler.
To be able to compile the Rocrail sources the make call must be extended with -std=c99.
The easiest way is to misuse the DEBUG parameter:

make -j4 DEBUG=-std=c99 PLATFORM=MACOS ORIGIN=LOCAL fromtar
