[Octave-bug-tracker] [bug #61393] [octave forge] (sparsersb) Crash while "pkg test sparsersb"

[Markus Mützel]

Follow-up Comment #38, bug #61393 (project octave):

That was a good hint. It looks like libtool didn't want to build a shared
library:

The first library it complains about is "libstdc++fs". It looks like its
implementation in GCC is incomplete (especially for Windows), and there is no
shared library for it. [1]
I worked around that by adding `ac_cv_lib_stdcppfs_main=no
ac_cv_header_filesystem=no` to the configure flags.

The other libraries seem to come from the `AC_FC_LIBRARY_LDFLAGS` macro. By
the looks of it, its output is completely broken (at least for Windows). I
worked around that by setting `FCLIBS="-lgfortran"` for the configure script.

With those changes to the configure command, a shared library `librsb-0.dll`
is built.

With that in place, the sparsersb package builds without any issues.

I guess that means that your pre-released version builds successfully for
Windows (when working around some platform specific quirks). 👍

Please, let us know when you are ready to release it, and we'll update to that
version in MXE Octave.
