Instructions for compiling the Acoustics Toolbox on Linux and MacOS

Get zip file from http://oalib.hlsresearch.com/AcousticsToolbox/ and unzip
Uses gfortran to compile, but other compliers are included in the Makefile there.
   If you don't have gfortran (type 'which gfortran' in command window), you will have to install it

• brew install gfortran (on Mac)
• apt-get install gfortran (on ubuntu linux)

After unzipping, you will have an 'at' folder

In a command window

• cd at
• make
• mkdir bin
• make install

All executables will be in the bin folder, which will probably have to be included in your PATH
export PATH="$PATH:/PATH_TO_YOUR_AT/at"

If you are having problems compiling on new Macs with the ARM processor

• Edit the Makefile
• change argument in FFLAGS from -march=native
• to -mcpu=apple-m2 ( for M2 processor) or
• to -mcpu=ARMv8.6-A ( for generic ARM processor instruction sets)
• and run make again

If you are getting this error on any OS
ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk/usr/lib/libSystem.tbd' for architecture x86_64

It is probably a gfortran library interference from anaconda. To fix

• conda deactivate
• Compile AT
• conda activate
