Hello!
I am new to this list - so this is maybe a newbie question: I have a PowerMac running Linux 2.6.10 and I want to cross-compile for a Freescale MPC8540 PPC (Book E, e500, SPE) machine. Well, I finally need a compiler suite for this e500 architecture which generates code for the e500...
Therefore I used Kumar Gala's patches
http://gate.crashing.org/~galak/crosstool-0.28-rc37-e500.patch.bz2 http://gate.crashing.org/~galak/crosstool-0.28-extra-patches.patch.bz2
for the latest crosstool-0.28-rc37 and did a demo-e500-ck.sh: -----8<--------------------------------------------------------- #!/bin/sh set -ex TARBALLS_DIR=$HOME/cross/crossdownloads RESULT_TOP=$HOME/cross/crosstool export TARBALLS_DIR RESULT_TOP GCC_LANGUAGES="c,c++" export GCC_LANGUAGES EXTRA_PATCHES="spe" export EXTRA_PATCHES
#BINUTILS_EXTRA_CONFIG="LDFLAGS=-all-static" #export BINUTILS_EXTRA_CONFIG #GCC_EXTRA_CONFIG="LDFLAGS=-static" #export GCC_EXTRA_CONFIG
# Really, you should do the mkdir before running this, # and chown /opt/crosstool to yourself so you don't need to run as root. mkdir -p $RESULT_TOP
# Build the toolchain.
eval `cat powerpc-e500.dat gcc-3.4.3-e500-glibc-2.3.3-spe.dat` sh all.sh -nounpack --builduserland --testlinux --notest
echo Done.

But I got the following result (beside an error due to a missing add-on directory 'spe' I had to create manually):

-----8<---------------------------------------------------------
I was googling for this bug and found some similar thing about in this list about 2 years ago but there was no solution for that. Can you please help me to get this thing working?
And the other story: I've tried to run the crosstools directly on the MPC8540 (e500) target, but it fails to compile, too - it stops at:
-----8<--------------------------------------------------------- + make ARCH=ppc oldconfig HOSTCC scripts/basic/fixdep fixdep: sizeof(int) != 4 or wrong endianess? 0x434f4e46 make[1]: *** [scripts/basic/fixdep] Error 2 make: *** [scripts_basic] Error 2 -----8<---------------------------------------------------------
I had a look at the code in fixdep.c... but I have no glue where to continue my search for mistakes.
Thank you in advance,
