failed to build

Hello,

I want to build the openbios image for use in coreboot, but it fails.
I am running a 32bit debian 8.10 vm.

$ make
/usr/bin/xsltproc
Building OpenBIOS for x86
Building...
error:
   AR    libfs.a
   CC    target/libgcc/ashldi3.o

make[1]: *** [openbios.multiboot] Error 1
make[1]: Leaving directory '/tmp/openbios/obj-x86'

if i select amd64 on a 64bit machine it works without a problem.

What is the problem here?

Thanks
Jens

Oops, that was me not handling the non-OFMEM PCI mapping case in the 
last set of updates.

The attached patch squash is enough to compile x86 for me, can you 
confirm that it actually boots on your setup?

ATB,

Mark.

Hi Mark,

thanks for the quick reply.
WIth this patch I can build the x86 version.

I should have said that I attempt to flash coreboot the first time and 
have not the equipment yet to do the flashing (but its ordered).
I hope that the stuff is coming in a few days so I can report if its 
working on real hardware.

Best Regards
Jens

Hi Jens,

That sounds really interesting! Sadly there isn't much x86 development 
happening on OpenBIOS at the moment since the current focus for x86 is 
on the UEFI BIOSs, however I generally try and make sure that it builds.

I was able to boot coreboot/OpenBIOS in QEMU as per the instructions at 
https://www.coreboot.org/QEMU#coreboot_v3_.2B_OpenBIOS, although that 
was a few years ago and it's not something I regularly do.

However I would expect that the basic functionality of booting into 
OpenBIOS with serial console/VGA driver and running an ELF executable in 
real mode to be working fine - if it's not then please let us know :)

ATB,

Mark.

Hi Mark,

I installed coreboot succesfully on my t430.
I build openbios in the x86 version and added the openbios-bultin.elf as addtional payload to the image (with seabios as primary, so i could easily test openbios )
Unfortunately when I start it, it doesn't recognize the keyboard and several messages "cannot manage <device name>...."
I know that the laptop keyboard is attached via PS/2, and in the drivers/pci.c is a PS2 Keyboard block.
Is there anything I can debug?

Best Regards,
Jens
