coreinfo compilation problem

[Warren Turkal]

The following is the output I get when trying to compile coreinfo.

wt@mediakitchen:~/projects/coreboot/coreinfo$ make
  CC      build/cpuinfo_module.o
  AS      build/cpuid.S.o
  CC      build/pci_module.o
  CC      build/coreboot_module.o
  CC      build/nvram_module.o
  CC      build/bootlog_module.o
  CC      build/ramdump_module.o
  CC      build/lar_module.o
  CC      build/multiboot_module.o
  CC      build/coreinfo.o
  LD      build/coreinfo.elf
/home/wt/projects/coreboot/coreinfo/build/cpuinfo_module.o: In
function `cpuinfo_module_init':

../libpayload/bin/../lib/libpayload.a(timer.o): In function `get_cpu_speed':
timer.c:(.text+0xe8): undefined reference to `__udivdi3'
../libpayload/bin/../lib/libpayload.a(printf.o): In function `print_number':

printf.c:(.text+0x379): undefined reference to `__udivdi3'
collect2: ld returned 1 exit status
make: *** [/home/wt/projects/coreboot/coreinfo/build/coreinfo.elf] Error 1

Is there something I am not doing that I should be doing?

Also, I had to manually symlink libpayload.config to .config in my
libpayload directory so that lpgcc would work. This should probably be
automated.

Thanks,
wt

apt-get install gcc-multilib

That should fix your problem. You're on a 64bit system and need 32bit
libgcc.

There's no symlinking required, but I think the docs need some updating.
The problem is that coreinfo must be pointed to an _installed_ libpayload
dir, not to the libpayload source directory.

Here's what the canonical installation instructions look like (similar
to FILO trunk):

svn co svn://coreboot.org/repos/trunk/payloads/libpayload libpayload-source
cd libpayload-source
make menuconfig
make
make DESTDIR=.. install
cd ..

svn co svn://coreboot.org/repos/trunk/payloads/coreinfo
cd coreinfo
make

We could also make libpayload an svn:external in the coreinfo dir like
FILO does, dunno which is the better choice on the long run.
