Hmm,

for me bigfoots script does not work on Ubuntu 19.10 for some reasons.
I have changed some lines, but now compilation of ggc9 fails with really trivial
error (missing stdio.h).

What I needed to change in bigfoots script:
- it checks for an sdk lha archive (don't know if exists anywhere,
but on morphos site there is only this archive sdk-source-20191006.tar.xz)
I removed the lha parts because they don't seem to be required
- make for gcc is called CFLAGS -m32 set. As I remember correctly, a 32 bit
env is not required anymore, so I also removed this argument

In the end I get the error above.
I don't know if the correct script was put to public.

That's the way I called the script:
