Rene seems to not replied yet, but the using of 'glibc' and 'rs6000' hints that the target is a 'RS/6000'-machine with AIX-something, not an embedded system for 'PowerPC' using 'newlib' as the C-library... The 'wrong file format' error would say that glibc has been compiled with the 'native' compiler, using a target 'rs6000-something'... Saying "I build the binutils, gcc and glibc without an error" can be true, but 'gcc' and 'binutils' are compiled using the native compiler, when the 'glibc' should be compiled using the 'rs6000-something'-target cross-compiler. Ok, the simple tests like 'file crt1.o', 'rs6000-<something>-nm crt1.o' etc. would reveal easily if the C-library really is 'rs6000'-code, not the native 'elf_i386'-code... Saying "I have no access to an rs6000 machine!" is really weird, when the right way would be to take the native libs & headers from a RS/6000-AIX- machine, and not use 'glibc' as the C-library (I don't think the rs6000-aix port is ready and working, the old glibc-1.09' was the last where other systems than Linux were somehow supported...). If trying to make a 'normal' ppc-eabi target cross-compiler using Cygnus newlib as the C-library, there shouldn't be much troubles and quite a lot people could help in this... The 'psim'-simulator is great and 'having no access to a powerpc-machine' doesn't hurt so much... (Ok, it should be capable to simulate even Linux/PPC and Solaris/PPC, but not AIX...) These were just my guesses...
