[Octave-bug-tracker] [bug #45082] mxe native build fails at gmp

[John Donoghue]

Follow-up Comment #8, bug #45082 (project octave):

I remember some newer versions of packages breaking the build of native mxe.

I recently just tied msys2 as well, and see that depending on what packages
are installed in msys2 will greatly effect how how in the mxe build you can
get. So far, I haven't reached a full build of octave using it.

As an alternate method, I am looking at being able to compile octave natively
from the installed mxe-octave, which from your comments below was one of the
methods you also tried.

One of the immediate issues with build from installed mxe-octave that I see is
that some of the 'tools' required to build octave are not supplied in the
installer, which really only cares about supplying the required libraries etc
to run octave.

To that end, I have added a --enable-devel-tools option to the mxe-octave
configure script, with the plan to provide the option to include the tools
required to build octave etc that are not needed by the normal
user/installer.

The main missing files I have seen (so far) is the qt build tools (Linux tools
are built for compiling cross octave, but windows binaries of uic, moc, rcc,
lrelease are not)

I have a patch to include them, which I am testing out now.
