[Octave-bug-tracker] [bug #62090] [octave forge] (io) Installation fails with spaces in path

[Markus Mützel]

Follow-up Comment #14, bug #62090 (project octave):

@gwiora: Thank you for testing. Even if it is still failing, it actually looks
better in Octave 7 than in Octave 6. 🙂

@Philip: You are right. This will probably affect many Octave packages out
there. (Maybe all that have a Makefile?) We talked about this a few months ago
in a developers meeting [1]. Back then, we decided to taggle this on a
"per-report" basis. This is the first report we received about this issue
since then.
The "nice" thing is that you are also a Windows user and might be better
equipped to test possible solutions than other package maintainers.
It's also a nice coincidence that you are planning a new release currently.
👍

Tbh, I'm not very firm when it comes to the internals of Octave packages. Is
the MKOCTFILE makefile variable supposed to be the (path and) name of the
`mkoctfile` executable *without any flags*? If it is, the following change
might help:

diff -r 11019b16535c src/Makefile

 clean:

@gwiora: I'm attaching a modified version of the io package where I did that
change. Can you install the io package in Octave 7 (in `C:\Program Files`)
from that file?
