Re: powerpc cross-compiler build failing

[Rob Ouellette <rouellet at ebmail dot gdeb dot com>]

Hello,

We are trying to build a c/c++ cross-compiler for the
SPARC/Solaris  and PowerPC/vxworks targets from the
gcc 2.9.3 source code.  I have downloaded the binutils v2.10.1
and installed it with the following command:

    /files2/bu10/configure --prefix=/apps/gnu2/ppc
--host=sparc-sun-solaris2.6 \
    --target=powerpc-wrs-vxworks

I ran configure on the source code as follows:

    /files/gcc-2.95.3/configure --prefix=/apps/gnu2/ppc
--host=sparc-sun-solaris2.6 \
    --target=powerpc-wrs-vxworks --with-gnu-ld --with-gnu-as

I put "/apps/gnu2/ppc/bin" and
"/apps/gnu2/ppc/powerpc-wrs-vxworks/bin" in my search path before
running
"/files/gcc-2.95.3/configure".

When I do a make(gnu make) I get the error,
/files2/gcc-2.95.3/gcc/stdlib.h:18: sys/feature_tests.h: No
such file or directory, as shown below.   I am unsure of why or
what to do.  I tried copying the needed files
from /usr/include but that didn't work.  I believe the
instructions I have say not to use the "--with-local-prefix"
option - which I was considering.

Any advise/recomendations are GREATLY appreciated!

Thanks,
-rob
