[LinuxBIOS] Build problem

Hi I am new to LinuxBIOS. I am using LinuxBIOSv2 .I am trying to build a
rom image for the khepri board from newisys. I do the following for the
build -

#cd LinuxBIOSv2/targets/
#./buildtarget newisys/khepri
#cd newisys/khepri/khepri
#make

I get the following error -

linuxbios_ram.o(.text+0x853c): In function `start_cpu':
: undefined reference to `_secondary_start'
collect2: ld returned 1 exit status
make[1]: *** [linuxbios_ram] Error 1

I am using gnu gcc 3.4.3

Can someone help me with this ASAP?

Rohit.

I don't have your hardware but I just tried the build and it worked
fine for me.  I got all the way to the payload error which is the last
step.

#define DISCLAMER_I_AM_NOT_AN_SMP_EXPERT

_secondary_start looks to me to be code that will start up the other
cpus in SMP.  Its assmembly that lives
'src/cpu/x86/lapic/secondary.S'.

'src/cpu/x86/lapic/lapic_cpu_init.c' copies that code into a area below 1M.

Unless this is your truly first attempt to build this then you should
do is a fresh check out into a new directory and re-try.  I've had
buildproblems with unresolved symbols in the past that were fixed by
clean checkouts.  The linuxbios build system is pretty complex and
sometimes it can get confused.

If you still have the problem after that then save the build info to a
file and grep through it looking for where secondary.S is assembled
and make sure it's making it into your linker statements.
