[Prex-devel] Relocation failed while loading prex

[pradeep s. <pra...@gm...>]

Hi,
First of all thanks for writing this RTOS because of which now I can spend
most of my time
hacking
I know this question has been asked before but I am not able to find any
answer.

If I compile with gcc 3.4.3, I get following compile time errors:
../arm/locore.S: Assembler messages:
../arm/locore.S:135: Error: register expected, not '#0x03' -- `orr r0,#0x03'
../arm/locore.S:142: Error: register expected, not '#0x1000' -- `add
r0,#0x1000'
../arm/locore.S:153: Error: register expected, not '#0x03' -- `orr r0,#0x03'
../arm/locore.S:180: Error: register expected, not '#0x80000000' -- `add
r1,#0x80000000'
If I compile with gcc 4.2.3
I get unresolved symbol errors for 'raise'.
After defining dummy function raise I was able to build prexos successfully
but when it boots(in QEMU) I
get following messages:

Panic: relocation fail

Has anybody faced this problem ?
Am I using right toolchain ?

Thanks,
