AFAIK, fpm has a link option in the toml file to support linking with BLAS and LAPACK. [build] ... link = ["blas"] However, I don’t understand two important things: How do I tell fpm where BLAS is to be found? How can the linking be made to work locally (I have OpenBlas in MSYS2) as well as in t…

These might help [image] Compiling simple Fortran program using fpm and local lapack and blas fpm I am using fpm and locally installed Lapack and Blas libraries to test the Ax=b for a simple case (without fpm the example works perfectly): here is the example program main…

The Fortran Standard Library now ships a full BLAS and LAPACK implementation in generic precision, that you can use either with the original API or with a NumPy-styled high-level API. External BLAS/LAPACK libraries are supported via a cpp macro. For example, you can define: [dependencies] stdlib =…

Thank you both. I was able solve the issue. Essentially, my problem was that I didn’t understand the practical result of adding link = ["mylib"] to the toml file. In the meantime, I realized that there is no magic: it “just” adds the flag -lmylib (for gcc). So, in my case, I just had to change to …

I just had a look. It’s amazing work. Yet another good reason to use stdlib. How did you guys do that? Did you parse the reference BLAS and LAPACK from netlib, converted that to fyyp and… and … and…?

The Netlib version is great in that the code is very well structured (although old). For example, if you have an external function, it will be in a block preceded by an “external functions” comment line, etc. So I did it with a custom Python script with a combination of code modernization, informat…

Hi Federico, I’m new to fortran and tried this a few days ago, worked like a charm if the use statements where done from app in the fpm project, but I’m still tryoing to make them work in src. perhaps you know what needs to be done

Hi @mcditoos , sorry I’ve just left for vacation. If you can show your issue with an example, I can take a look when I’m back thanks!

No worries, thanks for replying on your vacation, Enjoy it ! On another note. is there any plans to include matrix exponentials/ square roots and related functions in stdlib_linear algebra?

As you mentioned all functions of LAPACK and BLAS are available. Can you please point how I can I use dgeev? When I am using its shows an error that Error: Procedure ‘dgeev’ called with an implicit interface at (1) [-Werror=implicit-interface] compilation terminated due to -fmax-errors=1. Compil…
