Re: Problems Building GCC 2.95.2 on Concurrent Maxion (mips)

[Jim Wilson <wilson at cygnus dot com>]

I am not familiar with Concurrent Maxion systems.  Since gcc is very system
dependent, it is unlikely to work if it doesn't already support your system.

Using "mips" as the target will certainly not work.  There are many different
kinds of mips based systems available, and they are not interchangeable.
"mips" by itself will default to something inappropriate for your target.
Figuring out which target, if any, is the right one will be hard.  Try looking
at the list of mips-*-* targets gcc/configure.in.  mips-sni-sysv4 would be my
first suggestion, but you might also try mips-tandem-sysv4.  If neither of
these work, then there is probably no choice that will work.

Most old systems require ranlib to process archive files.  Some new systems
don't.  If you system doesn't have ranlib, then it isn't required.  Gcc should
figure this out on its own, but if it doesn't you can just alias ranlib to
"touch" or "true" or some other harmless command that always succeeds.

Binutils is just as system dependent as gcc.  If binutils doesn't already
know about your system (and it doesn't), then it is unlikely to work.

As with gcc, telling binutils that your target is "mips" won't work.  There
are too many different incompatible mips systems out there for this to work.
Try one of the two targets I mentioned above for gcc, but again, it is
possible that there is no choice that will work.

Binutils is apparently defaulting to a 64-bit target when you specify "mips".
If you are on a 32-bit system, then this can work only if the host compiler
supports a 64-bit type like gcc's long long.  In practice, this probably means
that you can't build it unless you have gcc.  However, since it is configured
wrong, it doesn't really matter that you can't build it.

In general, the GNU tools do not support mips SVR4 systems very well.
GNU tools mostly support the machines that GNU developers have access to,
and, historically, we haven't had access to these kinds of systems.
You should be able to get the things other than gcc/gdb/binutils working
though, as the rest of the stuff is not so system dependent.  Your GNU make
is probably OK.

-lmld is a library on some older mips systems.  Gcc is trying to link
against it because you configured gcc wrong.
