Cross compiler Alpha->powerpc problems

[Bob Koninckx <bob dot koninckx at mech dot kuleuven dot ac dot be>]

Hi guys,

I am trying to build the development tools for ecos on an alpha (rh. 7.0
distribution, 2.2.17 kernel)

My native tools are gcc-2.95.3, binutils 2.10.1

I downloaded gcc-2.95.2 (core + g++) and binutils-2.10.1

Binutils compiled fine and where installed under
/usr/local/crossgcc/powerpc-eabi

I then tried to build the compiler using the following commands


## PATH=/usr/local/crossgcc/powerpc-eabi/bin:$PATH; export PATH

## configure --target=powerpc-eabi \
## --prefix=/usr/local/crossgcc/powerpc-eabi \
## --exec-prefix=/usr/local/crossgcc/powerpc-eabi \
## --with-gnu-as --with-gnu-ld --with-newlib \
## -v 2>&1 | tee configure.out

This did not report any errors. The build phase dies with the message

Any ideas ?? Suggestions
