Thanks a lot for your help

I am not so strong in programming: how should I apply your patch?

Sincerely

Baptiste

I am using debian trixie with the official package for octave.

I try to port a matlab code using ode15s and encounter this error:

error: __ode15__: support for sundials_ida, sundials_nvecserial was unavailable or disabled when Octave was built

error: called from

    ode15s at line 324 column 22

Should I do a bug report?

This is a known issue, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1082580

Unfortunately there is no fix yet. And it is unlikely it will ever be fixed in trixie.

I posted a potential fix/workaround on Octave's discourse forum:

Improving MPI detection - maintainers - GNU Octave

Could that patch be used to enable these functions in Debian Trixie?
You'd need to regenerate the configure script after applying that change. Something like "autoreconf -fi" should do that.

I hope that is helpful.

Markus
