Hi Murray,

Is there a similar fix for gcc 3.0.4?

Thanks, My Hong

Hi All, a small but important thing... 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. Cheers! Murray... -- Murray Jensen, CSIRO Manufacturing & Infra. Tech. Phone: +61 3 9662 7763 Locked Bag No. 9, Preston, Vic, 3072, Australia. Fax: +61 3 9662 7853 Internet: Murray.Jensen@csiro.au
