problems building win32-hosted cross compiler

problems building win32-hosted cross compiler

[Rob Taylor]

I'm relying to my own mail here, just so the solutions known..
The problem turned out to be that gcc's spec file had been written with CR/LF's
and the spec parser was choking (it was reading asm_spec as being "/r/n"..)

Out of interest does anyone know why the spec was written with cr/lf's and how
to stop it?

Thanks,

nope. used tar -xzf ;)
that's not the issue. the spec file is generated when makeing gcc and gets
installed to ${prefix}/lib/gcc-lib/${machine}/${version}.

problems building win32-hosted cross compiler

[Rob Taylor]

I'm trying to build a win32 hosted cross compiler to powerpc-unknown-eabi with
the cygwin toolchain.
When I try to link a powerpc exec (i.e when xgcc tried to build a test of
libgcc), powerpc-unknown-eabi-ld freezes. passing --verbose gives

GNU ld version 2.9.5 (with BFD 2.9.5.0.22)
  Supported emulations:
   elf32ppc
using internal linker script:
==================================================

==================================================
and then freeze.

I'm configuring binutils with
--prefix=/usr/target-powerpc --target=powerpc-unknown-eabi

and gcc-core with

--prefix=/usr/target-powerpc --target=powerpc-unknown-eabi --with-exeext=".exe"
\
--with-newlib

Has anyone got any idea what's happening?

Thanks,
