Hello,
I'm currently upgrading a custom PPCBoot 1.1.5 port to U-Boot 1.0.0 for a custom 405GP-based board. At the same time, I thought it would be a good idea to upgrade my development system to SuSE 9.0 and tool chain to ELDK 3.0.
When I build U-Boot I get the following error when zlib.c is being compiled:
ppc_4xx-gcc -g -Os -mrelocatable -ffixed-r14 -meabi -D__KERNEL__ -DTEXT_BASE= 0xFFF80000 -I/home/ejf/u-boot/include -fno-builtin -ffreestanding -nostdinc -isy stem /home/ejf/eldk/usr/bin/../lib/gcc-lib/ppc-linux/3.2.2/include -pipe -DCONF IG_PPC -D__powerpc__ -DCONFIG_4xx -ffixed-r2 -ffixed-r29 -mstring -Wa,-m405 -mcp u=405 -msoft-float -Wall -Wstrict-prototypes -c -o zlib.o zlib.c {standard input}: Assembler messages: {standard input}:4998: Error: Relocation cannot be done when using -mrelocatable {standard input}:4999: Error: Relocation cannot be done when using -mrelocatable {standard input}:5000: Error: Relocation cannot be done when using -mrelocatable {standard input}:5001: Error: Relocation cannot be done when using -mrelocatable {standard input}:5002: Error: Relocation cannot be done when using -mrelocatable {standard input}:5003: Error: Relocation cannot be done when using -mrelocatable {standard input}:5004: Error: Relocation cannot be done when using -mrelocatable {standard input}:5005: Error: Relocation cannot be done when using -mrelocatable {standard input}:4969: Error: Relocation cannot be done when using -mrelocatable make[1]: *** [zlib.o] Error 1 make[1]: Leaving directory `/home/ejf/u-boot/lib_generic' make: *** [subdirs] Error 1
After doing a couple of quick Google searches, it appears that there might be some sort of bug in GCC. Does anyone know what the solution to this problem is?
I can build without the -mrelocatable flag. The board boots up but when it's time to run from RAM it crashes, probably because the resulting code is not relocatable.
Thanks for you help.
