 I am trying to build Coreboot v4 from SVN with default settings, but I get
 build failures. The build environment is Debian Linux on x86.

 Process goes as follows:
 {{{
 - check out coreboot trunk from SVN as per wiki instructions
 - run "make menuconfig", select QEMU hardware (default), ROM size either
 256K or 1M
 - run "make":
 }}}
 {{{
 coreboot.r5554$ make
     HOSTCC     util/romcc/romcc (this may take a while)
     ROMCC      mainboard/emulation/qemu-x86/bootblock.inc
     GEN        bootblock/bootblock.c
     CC         mainboard/emulation/qemu-x86/bootblock.s
     CC         mainboard/emulation/qemu-x86/bootblock.o
     GEN        bootblock/ldscript.ld
     LINK       bootblock.elf
     OBJCOPY    coreboot.bootblock
     HOSTCC     cbfstool/common.o
 [..cut..]
     HOSTCC     util/options/build_opt_tbl
     OPTION     option_table.h
     GEN        build.h
     ROMCC      romstage.inc
     GEN        romstage/crt0.S
     CC         mainboard/emulation/qemu-x86/crt0.s
     CC         mainboard/emulation/qemu-x86/crt0.initobj.o
 make: *** No rule to make target `/optbuild/lib/uart8250.initobj.o',
 needed by `build/coreboot.romstage'.  Stop.
 }}}

 I have tried this on two separate Debian/lenny machines with the same
 results. Is Debian somehow broken or Coreboot build scripts? Or am I
 making some mistake? What is this directory /optbuild and why coreboot
 build is trying to create/access it? I tried to grep "optbuild" from the
 sources, but it does not seem to exist there.

 Trying the same on Debian/etch (older release):
 {{{
 % make
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
 mkdir: cannot create directory `/optbuild': Permission denied
     ROMCC      mainboard/emulation/qemu-x86/bootblock.inc
     GEN        bootblock/bootblock.c
     CC         mainboard/emulation/qemu-x86/bootblock.s
     CC         mainboard/emulation/qemu-x86/bootblock.o
     GEN        bootblock/ldscript.ld
     LINK       bootblock.elf
 collect2: ld terminated with signal 11 [Segmentation fault]
 make: *** [build/bootblock.elf] Error 1
 }}}
 This looks like broken ld in Debian, or something going wrong in the build
 process.

Comment(by stepan):

 This is odd, for some reason "$(obj)" seems to be set to "/optbuild"
on
 your system. LD is definitely broken, since it segfaults.

 But it's something else that reconfigures your build directory to a
 directory you don't have write permissions to. You need to fix this first
 - probably the segfault will go away then, too.

 As for the broken toolchain please use the reference toolchain in
 coreboot/util/crossgcc.

Comment(by juhe@…):

 Ok, now I got it.

 The system is set up so that /home is not a directory but a symlink to
 /opt/home , which is the real location of home directories. I was doing
 the build under my home directory and the shell (pwd command) believed it
 was operating under /home rather than /opt/home.

 The Coreboot Makefile seems to do some computation on pathnames and in
 this case it was confused by the symlink along the path. So the end result
 was in some cases adding an extra prefix "/opt" to path names, e.g.
 "/optbuild/foo/bar" instead of "build/foo/bar".

 As the Makefile seems quite complicated for me, I "fixed" this by doing a
 chdir from /home/juhe to /opt/home/juhe, i.e. the same place via a
 different name, and everything works fine.

 Thanks for providing the missing clue to solving this!
