ForBLAS simplifies the compilation of the latest BLAS library using the Fortran Package Manager (fpm).

Install Instructions

1. Prerequisites:

Ensure you have a Fortran compiler installed on your system.

2. Clone the Repository:

Clone the ForBLAS repository from GitHub, including submodules:

git clone --recurse-submodules https://github.com/gha3mi/forblas.git
cd forblas
git submodule update --init --recursive

3. Install BLAS Using fpm:

Install ForBLAS using fpm:

fpm install --profile release --prefix .

The compiled library will be located in the lib directory.

Adjust installation directory, compiler, and flags as needed:

• Use --prefix <dir> to set the installation directory.
• Use --compiler <compiler> to specify your Fortran compiler.
• Use --flag '<flags>' to customize compiler flags.

Integrating BLAS in Your fpm Package

• Install and ForBLAS.
• Copy libforblas.a from the lib directory of ForBLAS to your fpm package's lib directory.
• Add link = ["forblas"] to your fpm.toml file.
• When using fpm, include --flag '-Llib' to specify the library directory.
