Hi all, I entered a new (for me) problem. I'm trying to pack to some RPM a full version of the cross compiler I've already built. I followed the classic three steps approach: a minimal gcc cross compiler with the "inibhit libc" patch to use for building the glibc, the glibc and, finally, the full gcc. For some strange reason the process stops at the last steps, when it is trying to use the already built glibc. To my big surprise I've noticed the linker is refusing to use the libc.so.6 object files because it cannot test which machine it is for. Thus, if a look at the libc.so.6 file, powerpc-linux-readelf -h libc-2.3.2.so ELF Header: Magic: 7f 45 4c 46 01 02 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, big endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: None Version: 0x1 Entry point address: 0x1ce40 Start of program headers: 52 (bytes into file) Start of section headers: 1266804 (bytes into file) Flags: 0x0 Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 7 Size of section headers: 40 (bytes) Number of section headers: 65 Section header string table index: 64 as you can see the Machine entry is set to None. Is this the expected behaviour? What may have I changed to blow it up? The configure options are the same (believe me or not) as for the successfully RPM-outside installation. Shall I look to the binutils or to the minimal cross complier? Thanks for your help. Lapo
