I am finally going to admit defeat and come ask for help on this. I am trying to build a cross-compiler to run on an x86 machine for several targets: ARM, MIPS, AVR, and m681x. I would like a single compiler to handle those 4 architectures in addition to the x86, eventually. However, for now, I am just trying to get the individual targets able to compile.

I can get the binutils to compile/install/run just fine. The compiler build, however, is not cooperating, and I am almost certain I am overlooking something remarkably simple, but I just don't see it. I have my source tree installed in /mnt/tmp/gcc-4.1.2 and I am building in /mnt/tmp/objdir. (I found one recommendation to always build in a seperate directory.) I configure it with the following (as run from in objdir):

../gcc-4.1.2/configure --prefix=/mnt/tmp --program-prefix=mips-elf- \
 --target=mips-elf --enable-threads=posix --enable-shared \
 --enable-languages=c --disable-checking --with-gnu-ld --verbose


This should, as I understand it, build the MIPS's compiler and after running "make install"put it in the /mnt/tmp/bin directory, prefixing each executable with "mips-elf-" right?

After configure runs, I just type 'make' to build the compiler.

Everything goes OK (now that I figured out the --enable-threads=posix thing), until I get to this (I apologize about the formatting, but I wanted to send exactly what I see):

                from ../../gcc-4.1.2/gcc/unwind-dw2.c:42:
../../gcc-4.1.2/gcc/gthr-posix.h:43:21: error: pthread.h: No such file or directory

OK, take a step backawards.  You're building a cross-compiler for MIPS, but
what operating system / C library do you intend to target?  gcc doesn't contain
a C library, and you are going to need one.  gcc also needs to know what OS
your target is going to run.

You can use newlib as a minimal target C library, but I'm not sure if that's
what you want.
