egcs1.1 - ppc cross compiler

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

I am trying the build a PPC cross compiler for a linux host and an
MPC860 target.  I also want to use RTEMS.  I also want to be able to
crosscompile an mpc860-rtems application from a Win32 machine.  I
thought I might be able to do a canadian cross on linux to build a Win32
hosted powerpc crosscompiler.  Is this possible or am I dreaming.  Note
that I do not want to use CygWin if at all possible.  The tools seem
very slow.  I would prefer to use create a MinGW32 cross-compiler or
maybe even DJGPP but I'm not sure how valid it is anymore.  I have the
following pacakges.

* binutils-2.9.1
* egcs-1.1b
* newlib-1.8.1
* rtems-3.6.0

I unpacked the egcs and binutils archives and put a symbolic link in the
egcs source tree to the binutils directory.  Does newlib and rtems need
a similar symbolic link ?
I have managed to compile a naitive version of egcs from the source
using gcc-2.7.2.3 that comes with RedHat 5.0 or 5.1.  Now I am trying to
build a cross compiler with the following configure options.

cd egcs-build
egcs-src-dir/configure --target=ppc-eabi --prefix=/usr/local/egcs
--enable-version-specific-runtime-libs --with-gnu-as --with-gnu-ld
--with-newlib --host=i586-pc-linux-gnu

With gcc-2.7.2.3 there was no need to add the --host option but the
assembler complained in the compile about no -ppc option.  So I decided
to make egcs the default compiler as I read in the SPECIFIC  file that
comes with egcs that it is strongly recommended to recompile binutils
with egcs if initially built with gcc-2.7.2.*

Looking through the newlib tree I can't find much related to powerpc
processors.  Does anyone know if it is possible to build a crosscompiler
for powerpc-newlib-rtems support with the packages that I am using ??


Thanks for any help or advice.
