This repo contains the project S2HAT
They are built using cmake (>= 3.18). Try cmake --help in case of doubt.
In a generic use, S2HAT requires few libraries:
- MPI_C
- MPI_Fortran
Then, one of the two following :
- FFTW3
- HEALPIX which must be compiled in FORTRAN
Ensure these libraries are available on your system. You may as weel explicit them in a file .bash_profile_s2hat to load before using cmake, where you explicitely give HEALPIX_DIR, the path to find the healpix libraries and headers (especially for the Fortran one) if you chose Healpix for the fourier transform calculations.
Note : For Mac M1, you may install FFTW using Homebrew
To build the library and install it at a given location (prefix), execute the commands:
cmake -S . -B build --install-prefix <path> -DBUILD_x86_64=ON
cmake --build build
cmake --install build
or
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=<prefix>
cmake --build build
cmake --install build
