Now that I got the gccsdk building, I tried my next step, which is
building it on my NAS. It's a QNAP TS-431P2, which is an ARM model. I
tried building a docker image for it, using this docker image
here: https://github.com/kuroneko/docker-riscos-gccsdk .
It seems to do the correct thing, but it also fails during build. It
builds under an ubuntu image, so it should be pretty close to the
build on my machine which was OK, so I think it has to do something
with it being an ARM model, which causes a problem. The problem seems
to be this:
gcc -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall
-Wno-narrowing -Wwrite-strings -Wcast-qual -Wstrict-prototypes
-Wmissing-prototypes -Wmissing-format-attribute -pedantic
-Wno-long-long -Wno-variadic-macros -Wno-overlength-strings
-Wold-style-definition -Wc++-compat -DHAVE_CONFIG_H -I. -I.

I found a reference to this problem
at https://www.riscosopen.org/forum/forums/11/topics/9097 (search
for SUBTARGET_EXTRA_SPEC_FUNCTIONS) but that again references a mail
in this list saying the problem has gone away, but that doesn't seem
to be the case for me.
I'll try to do the same solution as in that posting, but is there a
proper solution?
Thanks
