toolchain compiling questions

[Philippe De Swert]

Hello,

I tried to compile a m68k-unknown-linux toolchain. I first used DanKegem's
crosstool and it compiled ok. (with gcc3.3.1 and glibc 2.3.2). Now I try to
build it by hand on the same machine with exactly the same switches (after I
removed the already build toolchain). Now I always run into this. It happens
when I build the full glibc.
When I add --disable-shared it compiles, but then it generates another error
when building the full-gcc.

Could you tell me what I'm missing.

the glibc-error:

the gcc error:

I don't have the time now to reproduce it, but it is something about libiberty
complaining that the compiler doesn't work...

this are the exports I use and I install in /usr

export PREFIX=/usr
export BINUTILS_DIR=binutils-2.14.90.0.5
export GCC_DIR=gcc-3.3.1
export GLIBC_DIR=glibc-2.3.2
export LINUX_DIR=linux-2.4.21
export TARGET=m68k-unknown-linux-gnu
export TARGET_CFLAGS="-O"
export KERNELCONFIG=$PWD/m68k.config
export GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.2
export BUILD="/mnt/cross/manual/gcc-3.3.1/config.guess"
export CPU="i686"
export PATH=$PREFIX/bin:$PATH

And another question, while I am at it...
What is the impact of the C-library you choose for your cross-compile toolchain?
What if I have a toolchain with glibc and want dietlibc or newlib on my
target...? Do I have to make another toolchain for every platform with a
different c-library? Or do I just have to be carfull with the linking?

Thanks,

Philippe
