OpenBIOS fails to build on sparc32/64 hosts

[Aurelien Jarno]

Hi,

Trying to build OpenBIOS natively on sparc32 or sparc64 host, I get the following error:

LINK  openbios-unix
libopenbios.a(load.o): In function `load':
/home/aurel32/openbios-devel/obj-sparc32/../libopenbios/load.c:41: undefined reference to `sys_info'
/home/aurel32/openbios-devel/obj-sparc32/../libopenbios/load.c:41: undefined reference to `sys_info'

It seems only sparc32/64 have CONFIG_LOADER_AOUT. The sys_info variable is defined in 
arch/sparc{32,64}/boot.c, but this file is not used to build openbios-unix. Any new what would be 
a real fix here, besides disabling CONFIG_LOADER_AOUT?

Thanks,
Aurelien

Hmmm. What's strange is that I would expect x86 to fail in the same way, 
and it builds fine on my native x86 host here. I'd start by having a 
quick look there and comparing the differences.

HTH,

Mark.

I also tried on x86, but it doesn't fail as CONFIG_LOADER_AOUT is not
enabled on this platform.

Ah okay. I currently have my final rework of the boot/load/go code which 
is fairly close to commit (and touches parts of this code) so once this 
is in, I'll try and take a quick look.

ATB,

Mark.

The real problem is that Unix target is not cleanly separated from
bare metal versions but some HW initialization stuff leaks in, like
the begin of unix.c. The target is also a bit hard to keep in synch
with the other targets. Some kind of cleanup would be nice, I don't
have a clear plan though.

I've just committed a fix.

Thanks a lot, I confirm it works.
