[ECOS] trying tx49 ref4955 design

[e.stiebler]

Hi all,
tried my first steps with ecos on a Toshiba TX49 (MIPS).
According to "building a toolchain" I built:
binutils-1.16.1,
gcc-3.4.4,
and got the ecos version from the AnonCVS.

When I try to compile it with make I get during the compiles something 
like :
mips-tx49-elf-gcc -g -mips2 -EB -mabi=eabi -nostdlib -Wl,--gc-sections 
-Wl,-static -L/AD1/SHARED/ECOS/test/install/lib -Ttarget.ld -o 
/AD1/SHARED/ECOS/test/install/bin/gdb_module.img src/stubrom/gdb_module.o
/AD1/SHARED/ECOS/gnutools/mips-tx49-elf/lib/gcc/mips-tx49-elf/3.4.4/../../../../
mips-tx49-elf/bin/ld: 
/AD1/SHARED/ECOS/gnutools/mips-tx49-elf/lib/gcc/mips-tx49-
elf/3.4.4/libgcc.a(_udivdi3.o): ABI mismatch: linking O32 module with 
previous EABI32 modules

Any idea, what I did wrong ?

Cheers & Thanks

libgcc.a is provided by the compiler. It looks like libgcc.a is
compiled using a different Application Binary Interface than what eCos
was compiled with.

Try looking at the options you can pass to the configure script when
you build the tool chain. Is there anything to control the ABI it
uses?

I used pretty much what's on the "building toolchain" webpage.

So setting :

ECOS_REPOSITORY=/AD1/MIRRORS/Mirror.Linux/ECOS/ecos/packages ; export 
ECOS_REPOSITORY
ECOS_GNUTOOLS=/AD1/SHARED/ECOS/gnutools ; export ECOS_GNUTOOLS
ECOS_TARGET=mips-tx49-elf ; export ECOS_TARGET

I compile binutils with :

#!/bin/sh
../binutils-2.16.1/configure \
--target=$ECOS_TARGET \
--prefix=$ECOS_GNUTOOLS/$ECOS_TARGET
make all
make info
make install

and gcc with:

#!/bin/sh
../gcc-3.4.4/configure \
--target=$ECOS_TARGET \
--with-gnu-as \
--with-gnu-ld \
--with-newlib \
--enable-languages="c,c++" \
--prefix=$ECOS_GNUTOOLS/$ECOS_TARGET \
--with-gxx-include-dir=$ECOS_GNUTOOLS/$ECOS_TARGET/include
