[linuxdc-dev] Newbie having trouble with gcc

[Renegade M. <dra...@sp...>]

Hello. I've been trying to build a cross compiler but so far have had no
luck. Following the instructions in the Tools section, binutils installs
just fine. But when building gcc, there are problems. Compilation goes for
awhile and then i get this:

as: unrecognized option `-little'
make[2]: *** [libgcc/./_ashiftrt.o] Error 1
make[2]: Leaving directory `/home/build/build-gcc/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/home/build/build-gcc/gcc'
make: *** [all-gcc] Error 2
make: Leaving directory `/home/build/build-gcc'

I've never tried building a cross compiler before. I'm running a Red Hat
6.2 system. I tried upgrading some of the compilation tools, but i still
run into the problem. Here's the versions of some of the tools that i'm using:

make - 3.79
gcc  - 2.95.3
ar   - 2.11.2

Any ideas? Any help would be greatly appreciated. I would really like to be
able to build software for my Dreamcast so that i can start developing for
it and learn how to port packages to it.

Make sure that the cross-compiled binutils is on your PATH after you build
them.  The error above is from gcc's cross-compiler system not being able
to find the cross binutils and falling back on your system (presumably
i386-based) assembler.

Thank you for your response.

I am using /usr/local/sh-linux as my target directory. I already had
/usr/local/sh-linux/bin as the first entry in the PATH. Should i have a
different directory in the PATH as well?

Hmm, no that should be correct.  Could you post your configure command
lines for binutils and gcc?

Here is the complete list of commands that i have run so far. If it would
help to see the output of the configure and make commands, i can post them
to a web page upon request. Anything i'm doing wrong here?

You forgot --prefix=${PREFIX} here.
