Help to compile psp gcc 4.3.0 on linux

[sauron_le_noir]

Is there a upgrade of the toolchain.sh for linux available
that use the gcc 4.3.0 or gcc 4.3.1 as target cross compiler ?

[jsharrad]

There's a patch on these forums somewhere to use gcc 4.3.0 with the toolchain, which I used a while back, but I found that my programs ran a tiny bit faster when compiled with 4.1.0.

i have downloade gcc 4.3.0 patch with the patch found on the forum
create a psp-build directory
launch this script:
#!/bin/sh

LANGUAGES="c,c++"

CFLAGS="-O2 -fomit-frame-pointer " \
BOOT_CFLAGS="-O2 -fomit-frame-pointer " \
BOOT_CXXFLAGS="-mthreads -fno-omit-frame-pointer -O2" \
BOOT_LDFLAGS=-s \
../configure \
--enable-languages=$LANGUAGES \
--disable-multilib \
--with-gcc --with-gnu-ld --with-gnu-as \
--disable-shared --disable-win32-registry --disable-nls \
--enable-cxx-flags="-G0 --disable-werror" \
--target=psp \
--with-newlib \
--prefix=/usr/local/pspdev \
--with-gmp \
--with-mpfr

the compiler is generated without problem but when he must genereated the libgcc
i've got this error
