Hello everybody, Very often, I need to write Python wrappers for my Fortran libraries where I create a shared library of my Fortran code and plug it into Python through its C API. The shared library will have, at least, dependencies on libgfortran and libquadmath. I was wondering what do you think…

I haven’t thought of this approach to create a dedicated package for the redistribuable libraries. Thanks :slight_smile:

I also thought that asking the Windows user to install msys2 might be cumbersome. I am not familiar with the macOS ecosystem and I don’t know if it needs to be signed or notarized :frowning: After looking at this discussion , it seems that for macOS homebrew is the way to go.

I distribute an OSX binary created from gfortran and have had no user complaints. It seems that with recent versions of OSX there is a popup that warns the user that the binary might be dangerous, but apparently users are used to that and click through it. I add the options -static-libgfortran -s…

Currently, this is what I am doing. I use the static linking for macOS and Windows to avoid dependencies on libgfortran and libquadmath. On Linux (centos and Debian) the static linking is not possible. I was just wondering what would be the best way in the case I cannot use the static linking.

On Centos 7 and Debian 12, I have tried the static linking for libgfortran and libquadmath and I got an error from the linker saying that the static versions of the libraries (libgfortran*.a and libquadmath*.a) are not available. After some googling, I found that in fact many distributions do not p…

[image] mskocic: After some googling, I found that in fact many distributions do not provide the static versions of libgfortran and libquadmath. OK, in Ubuntu 23.10 I have the .a and .so of libgfortran, but indeed the libquadmath is available only in .so.

Making your library into a conda package is another solution to this problem. It does mean your users have to install conda and perhaps be required to understand conda environments (although there are ways to build a stand-alone installer for a conda package that somewhat hides that). The gfortran a…

I’ll take a look at packaging for conda even though I am not very familiar with the conda eco-system. Thanks! :slight_smile:

Distribute shared libraries or not?

This might be a solution for Windows users Quick Installer for Windows for quickly installing and setting the gfortran compiler as well as all necessary libraries.
