Hi,
Current git fails to compile for me with:
Building ld scripts (version "pre-0.6.2-20101219_191912-tata") Traceback (most recent call last): File "./tools/layoutrom.py", line 573, in <module> main() File "./tools/layoutrom.py", line 554, in main info16 = parseObjDump(infile16, '16') File "./tools/layoutrom.py", line 538, in parseObjDump reloc.symbol = symbols[symbolname] KeyError: '.rodata.__func__.2140' make: *** [out/romlayout16.lds] Error 1
The interesting parts of the associated objdump are:
Sections: Idx Name Size VMA LMA File off Algn [...] 110 .rodata.__func__.2140 0000000a 00000000 00000000 000304fc 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA [...] SYMBOL TABLE: [...] 00000000 l O .rodata.__func__.2140 0000000a __func__.2140 [...] 00000000 l d .rodata.__func__.2140 00000000 [...] RELOCATION RECORDS FOR [.debug_info]: OFFSET TYPE VALUE [...] 0001419f R_386_32 .rodata.__func__.2140 [...]
So the relocation record points to the section and not a symbol, and the script dies. What can I do?
Best,
OG.

That's odd. It shouldn't even have tried to parse the debug sections. Can you email me a tar file of the build after running "make clean; make"?

Sure, http://dspnet.fr/~galibert/seabios-work.tar.bz2
Despite the name, it's a pristine clone.

I checked further, it's not crashing on the debug section but on a following one: RELOCATION RECORDS FOR [.text.handle_02]: OFFSET TYPE VALUE 00000002 R_386_32 .rodata.__func__.2140

Yeah - more binutils oddities. Does the patch below help? What distro did you find this binutils on?

It compiles with it, thanks. I'll tell you if it fails in testing.
I use gentoo, which means compile-from-source. It's binutils-2.20.1.tar.bz2 with the patches from binutils-2.20.1-patches-1.1.tar.bz2 which you can find both in a gentoo distfiles near you. ftp://ftp.proxad.fr/pub/Distributions_Linux/Gentoo/distfiles/ in my case.
Best,
OG.
