[fpc-devel] Freepascal on SPARC, MIPS(EL) and ARM GNU/Linux hosts

[Sunil Amitkumar Janki]

I want to know how to build Freepascal so it runs on SPARC,
MIPS(EL) and ARM GNU/Linux. For the latter two I will probably
first have to cross-build to these architectures if possible but I
don't know how to do this yet.

This is the error I get when I build FPC 2.2.0 on SPARC using
FPC 2.0.0:

I don't know if ARM and MIPS host support do in fact exist at all
but if not I would like to add these. I am not too knowledgeable
about ARM assembly and differences for the various versions.

I do have some experience and documents on MIPS assembly so
I should have to get by on that with the help of information across
the internet. Any help will be appreciated.
