I am using the latest gcc from cvs (3.4 20030608 (experimental)) and if you build the cross compiler for a powerpc/linux target, it leaves out the "fixup" stuff for the "-mrelocatable" command line option. If you then want to use that cross compiler to build "u-boot", it stuffs up with messages from the Assembler that looks something like this (on certain C files): ... Error: Relocation cannot be done when using -mrelocatable Since "-mrelocatable" is usually not used for Linux programs, I can't see why they did this. Rather than have two different cross compilers, one for linux and one for "other", which you use to compile u-boot, I chose a simple fix - patch the file "gcc/config/rs6000/linux.h" as follows: --- linux.h 2003/06/13 16:41:53 1.3 +++ linux.h 2003/06/20 01:28:53 @@ -84,7 +84,8 @@ #define TARGET_64BIT 0 /* We don't need to generate entries in .fixup. */ -#undef RELOCATABLE_NEEDS_FIXUP +/* well I do need them! */ +#define RELOCATABLE_NEEDS_FIXUP #define TARGET_ASM_FILE_END file_end_indicate_exec_stack Hope this helps someone.
