Fails to install any octave-* packages (possible reason: "unable to find the mkoctfile command")

[alatina (Andrea L)]

My macports fails to install any octave-* packages. Example:

sudo port install octave-general
--->  Computing dependencies for octave-general
--->  Configuring octave-general
Error: Failed to configure octave-general: configure failure: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_octave-general/octave-general/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port octave-general failed

If I try the same within octave, it also fails but explains why:

octave:1> pkg install -forge general
pkg: unable to find the mkoctfile command, Octave installation is incomplete
error: called from
    __gripe_missing_component__ at line 53 column 3
    configure_make at line 40 column 7
    install at line 184 column 7
    pkg at line 437 column 9

Apparently it does not find the 'mkoctfile' command....

I do have the very latest macport of octave installed.

Please attach the log for octave-general.

Why are you installing a package from within octave?

Under MacPorts, octave packages are supplied as ports. Thus, if you want to install the general package you run the following command:

sudo port install octave-general

This will install any other octave package dependencies, if needed.

[alatina (Andrea L)]

Yes, I know I should do it through macports. My attempt to install the package from within octave was just because

sudo port install octave-general

fails.

The attempt from within octave failed as well, with the same error: "unable to find the mkoctfile command, Octave installation is incomplete" main.log file, line 140.

What does

ls -l /opt/local/bin/mkoctfile

say?

There is no need to CC the reporter.

I believe this error is a result of a recent change to octave.
I am working on a fix.

[Schamschula (Marius Schamschula)]

Even though octave @4.4.0_4 shows the correct path to mkoctfile, in my case /opt/local/bin/mkoctfile, which is a symlink to /opt/local/bin/mkoctfile-4.x.x, the pkg command can't find it.

Indeed, mkoctfile exists and is a symlink to mkoctfile-4.x.x. It works, at least from the command line:

macbe16641:~ andrea$ ls -l /opt/local/bin/mkoctfile
lrwxr-xr-x 1 root wheel 15 Jun 13 09:57 /opt/local/bin/mkoctfile -> mkoctfile-4.x.x
macbe16641:~ andrea$ /opt/local/bin/mkoctfile --version
mkoctfile, version 4.4.0

Thank you for the information.
I was unaware of the change and was giving out bad advice.

This is definitely a problem with the octave port.

mkoctfile-4.x.x exists, but octave is looking for mkoctfile-4.4.0, which does not exist.
This is due to a mistake in a recent change, which in turn was trying to fix another problem.

I think I know a fix to both problems, but it may take me a day or two to find the time to implement it.

Alright, take your time.

At least now I know what workaround I can use to temporarily fix the problem. Thanks a lot!

For the records, the workaround (i.e. creating a link to mkoctfile-4.x.x called mkoctfile-4.4.0) didn't really work. So, I will just wait for your fix.
