Unfortunately I got stuck at the dreaded problem with libreadline. 
Several targets fail with error:

gawk: symbol lookup error: 
/home/pavel/mxe-octave-4c5a70572b2b/usr/lib/libreadline.so.6: undefined 
symbol: UP

There are several patches to libreadline in src, IMO some of them 
ifdef'd only for windows. But they seem ok with this respect. The actual 
build of readline 6.2 (download log, build log) seems perfectly OK.

The devel packages will very likely work, just compiling octave 5.1 
first :-)

You are right. Octave from flatpak does not have e.g. units (for package 
miscellaneous), pg_config (for database) etc in the layer 
/app/octave/bin/. I am not sure it is possible to pkg install these 
packages on octave running in flatpak. I tried to include these missing 
requirements to the flatpak dir in /var/lib/flatpak/...., to no avail. I 
would prefer compiling octave from sources (MXE) without flatpak.

Thanks a lot for any suggestion with the readline problem. Apart of that 
I think the build will go OK.

Best regards,

Pavel.
