[Message part 1 (text/plain, inline)]

I can confirm that this was the issue.

I had to explicitly set both F77 and FC to "no". Even if there is no Fortran compiler found, configure sets them to "ifc".

I was thinking to suggest both libtool and automake to add options to explicitly disable checks and test for specific languages. Obviously, this needs a separate discussion.

If I look at output from configure...

When configure checks for Fortran compiler, it finds mingw's gfortran:

```
checking for gfortran... gfortran
```

And then:

```
checking whether the gfortran linker (link.exe -nologo) supports shared libraries... yes
checking dynamic linker characteristics... Win32 ld.exe
```

Could this be the cause?

Thank you!

Okay, if you do try it, I would be interested to see if the behaviour
changes.

Thank you for the logs! I will look through them and see if I can
reproduce your issue.
