gcc - ada cross compiler question

[mark]

Hi:

I've built a couple gcc/ada cross compilers in the past but I'm really 
having trouble with this one.  I have to build a gcc 4.1.2 based Ada 
cross compiler.  The host is Linux.  The target is a 
powerpc-mpc8248-linux-uclibc (PowerPC 603, Linux 2.6.20, uClibc-0.9.29). 
  When building the compiler, I get a message

  cp -p ../../gcc/ada/sinfo.ads ../../gcc/ada/nmake.adt 
../../gcc/ada/xnmake.adb ada/bldtools/nmake_b
(cd ada/bldtools/nmake_b; gnatmake -q xnmake ; ./xnmake -b ../../nmake.adb )
gnatbind: Cannot find: s-stalib.ali
gnatmake: *** bind failed.

Would anyone know why the error occurs?  Its confusing why s-stalib is 
not being compiled.  I am using gcc 4.4.4 as the host compiler.

Thanks

Mark

IIRC, it is necessary to use the exact same version of GCC for the
native and cross compilers.  You can use GCC 4.4.4 only as the bootstrap
compiler in this case.  What stage does the error happen in?

GNAT is very picky about the build compiler. Ludovic is right in that
you have to use a 4.1 compiler, better the exact matching version,
i.e. gcc-4.1.2 in your case.

Using a higher version number for bootstrapping older GNAT versions
requires that you don't treat warnings as errors during stage 1. This
is a usability bug in the Makefiles, IMHO.

BTW, there is only a single stage when building cross compilers.

I had deleted the original post.  I was using a wrong adalib.  Problems 
still remain but I'm posting them in gnu.gcc.help.  Thanks for your 
reply anyway.
