That surprises me.

First of all, for me the patch from this bug report is needed to make a few
OF packages compile:
https://savannah.gnu.org/bugs/index.php?43318
(I'd appreciate if a core dev could review that patch, please)

But even with that patch, the following OF packages included in mxe-octave
won't install at all with --enable-64:
- image
- odepkg
- fl-core
- netcdf

Have you tried "pkg list" to see which packages do get installed
successfully?
As you've adapted build_packages.m to catch unsuccessful OF package installs
(thanks for that BTW!) it is easy to overlook packages that didn't get
installed.

Now that I know that it is 7zip on the Windows side that doesn't unpack all
files correctly from .tgz or .tar.gz archives, I think so too :-)

I have been untaring using a local copy of mingw/msys and then running the
