No, you have to build them from the hg sources.  If you are building all
of Octave and its dependencies, that's not much more work to do and
there is a target in the mxe-octave Makefile to do it.


I am still lost, maybe I misunderstood something.
First I had to install: "PCRE library" (on ubuntu 20.04: "pcre2-utils")
because of this message:
configure: error: to build Octave, you must have the PCRE library and header files installed

After "./bootstrap" I stayed inside the root-dir of the repository clone (for me: '~/hg/mxe-octave')
and gave the command:
nice -n 19 make all 7z-dist JOBS=8 hg-octave-dist hg-octave-branch=stable
The result was:
[build]    stable-octave

Failed to build package stable-octave!

I thought that this command "nice -n 19 ... hg-octave-dist hg-octave-branch=stable" takes care of the necessary
Do I need to modify this command? And if so, what would be an example of an tailored command?

The command:
make dist
results in a file: "mxe-octave-a65cacd05892.tar.gz"
Does it make sense to copy this into the pkg-dir?

cp ./mxe-octave-a65cacd05892.tar.gz ~/builds/octave_pkg/octave-6.0.1.tar.lz
