RE: Help w/ gcc cross build failing

["Jon Watson" <j-watson at airvananet dot com>]

After unpacking the distribution .tar.gz files I created a subdir called build and ran configure (from the build subdir) like this:

../configure --target=powerpc-eabi --prefix=/cygdrive/c/gnutools/gcc-3.4.1 
--without-headers --with-as=/cygdrive/c/gnutools/binutils-2.14/powerpc-eabi/bin/as 
--with-ld=/cygdrive/c/gnutools/binutils-2.14/powerpc-eabi/bin/ld 
--with-local-prefix=/cygdrive/c/gnutools/gcc-3.4.1/powerpc-eabi --disable-shared 
--disable-win32-registry

I have already built the binutils (2.14) for powerpc-abi. I installed the binutils
(for powerpc-abi) in a separate subdir I'm using for the tool chain I'm trying 
to build.

I still had to edit the generated Makefiles to get them to use the right binutil 
tools for the powerpc-eabi target. The changes were very minor - I just filled in
the definition of the variables like AR_FOR_TARGET.

What did you use for the "configure" command parameters before 
running make?  Did you supply the "--target=powerpc-eabi" option?

If you properly configure, you don't need any explicit target on
the make command line.  You will need to limit the build to just
the C compiler until newlib is built.  If you use a full gcc tar
file, i.e. gcc-3.4.1.tar.bz2 rather than gcc-core-3.4.1.tar.bz2,
you would want to add LANGUAGES="c" to your make command.

Once that completes, do a "make install" and build newlib.  Then
you can go back and rebuild gcc with C++ support if you need that.

Right - you need that for a native compiler build.
