Problems of the corss-compiler.

[Whitney, John]

Depending on what processor you are using, you may or may not need to
compile the development environment to use software floating-point.  The
860 serial does not have the FPU (at least, none that I know of do), while
the 8260 and 603 series do.

Trying to execute code compiled with hardware floating-point on a processor
without this will result in a crash (floating-point exception, I believe).

Most of the tools compile fairly well for software floating-point, but the
glibc code needs some source modification.

Hi everyone.
First, I'm sorry for my weak English.

Well, Now I build a powerpc cross-compiler.
so I compiled some binary using that cross-compiler, but
I have some problems.

I think cross-compiler is not problem.
because I compile kernel with that cross-compiler, and
kernel runs good.

but, init, shell etc thease binaries have some problems.
shell cant recieve argument, and some binaries print 'segmentation fault'

I don't know why my compiler can't compile well.

These are the packages that I used.
1. binutils-2.10
2. gcc-2.95.2
3. glibc-2.1.3 (add-ons : glibc-crypt-2.1, glibc-linuxthreads-2.1.3)

First, I compile the binutils for powerpc cpu.
Second, I build cross compiler with gcc.
Third, I compile glibc for powerpc with cross compiler that I made.
Last, I re-build cross compiler include glibc for library.

Please tell me what do you think about that And why the problem happen.
I'll wait your answers.
thank you.
