building cross compiler for ppc

[David L]

I need to add fortran support to a cross compiler that my company
uses.  We got the compiler from codesourcery but it lacks fortran
support, so I'm trying to build one from scratch.  First I'm just trying
to replicate the functionality that we currently have (C/C++) cross
compiler from i686-linux to powerpc-linux.  But I can't get that
to compile.  I get this error:


i686-redhat-linux-gcc -c  -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE
-W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes

Here is what I tried:

/bin/rm -rf /tmp/gccbuild
/bin/rm -rf /tmp/mygcc
/bin/rm -rf /tmp/mygcc/sysroot
/bin/rm -rf /tmp/mybinutils

cd gcc-4.4.2
ln -s ../mpfr-2.4.2 mpfr
ln -s ../gmp-4.3.1 gmp

cd ../binutils-2.20
