It's good that you bring up the LAPACK and BLAS packages because their presence on the package manager needs to be fixed.  Simply Fortran itself ships with OpenBLAS on Windows, Linux, and macOS/Intel, which is a highly optimized BLAS and LAPACK implementation.  On macOS/ARM, Simply Fortran links with Apple's Accelerate framework for its LAPACK and BLAS implementation.  These options are all significantly faster and more efficient than Netlib's reference LAPACK and BLAS implementations, which are what we provide in the package manager.

What actually needs to happen is for us to remove LAPACK and BLAS from the package manger altogether since Simply Fortran already ships with it.  You can enable the built-in LAPACK and BLAS linking without the package manager in Project Options under "Linker."

I have to say that the more I work with SimplyFortran, the more I like it. It is really working very well.

One question please: could you check the versions of Blas/ Lapack which are in the package manager and update them if possible? (latest available version of Lapack seems to be 3.12.1 from Jan 8, 2025; acc. the description in the package manager, there is version 3.5.0).
Thank you very much, Alfred
