No. You've already said that you've got a Debian (presumably x86) system
available. Use that, and follow the instructions I put in the wiki page:
I wrote those line-by-line as I was doing the job (there might be a
minor glitch in there somewhere because I changed a directory layout
part way through, but apart from the the commands are still the same).
You start off with a /specific/ version of binutils, slightly older
won't work and somebody's already said in the ML that newer ones are
problematic (you /have/ read that thread I pointed you at, haven't
you?). You build yourself a cross-compiler, you then use that to build
yourself an RTL. I did that about a week ago, it works.
Having the cross compiler and RTL, you should then be able to either
build a native compiler etc. or to compile trivial programs (some fancy
stuff won't work yet because you haven't built the full FCL). The native
compiler can be copied onto your mipsel system, and is currently good
enough to recompile itself.
As LBSC used to write, "follow the words and music and you won't go
wrong". However if you continue to guess and not to follow the advice
people are giving you you won't get anywhere: the compiler has only been
working for a few weeks and everything is still comparatively fragile.
Apologies if I sound slightly less patient than Henry, Michael et al,
but the basic compiler *DOES* work (I certainly don't have the
experience to apply non-standard fixes on the fly, and if I did I'd have
mentioned it). However as I described in a different thread a few days
ago there are still problems running Lazarus natively on MIPS, so don't
try that unless you've got time to start investigating the outstanding
code generation issues.
