Error installation for octave-optim

  • How can I replicate the Octave problem?

Over Arch Linux system (virtual machine, docker container o real machine) install some AUR helper or in other hand install octave, the dependencies octave-statistics, octave-struct, later run

$ git clone https://aur.archlinux.org/octave-optim.git
$ cd octave-optim
$ makepkg
  • What did I expect to happen and what did happen?

I expect that the package will be installed as 1 week ago, but we have an error message.

That is probably bug #60920, [octave forge] (optim) New warnings on loading package
The bug has been fixed upstream. But no new release has been made in the meantime.
For possible workarounds, see: Signal package does not install with Octave 7 - help - GNU Octave

Thanks for quick response.

Thank you.

From the savannah link is the comment: “The whitespace before ‘–’ and ‘++’ is now removed in vfzero.m and lsqlin.m. Closing as fixed.”

I edited the two aforementioned files in my 7.1.0 installation as recommended, and I no longer get the following warnings on the “optim” package load:
