No I have not fixed the problem.  If you have any suggestions I would
be appreciative.

Doh! did you fix your linker?  Generally 'undefined reference' comes
from loadtime.

ali

I am using the Xilinx Kernel for the Xilinx FPGA core.  I am
attempting to use the Signal catch to send a packet out once every
second on a ping.  I included the signal.h and unistd.h files but when
I call alarm to try and trigger a signal each second the compiler
complains.  The errors are as follows.

/cygdrive/c/DOCUME~1/s262256/LOCALS~1/Temp/ccikIBdx.o: In function
`sig_alrm':
/cygdrive/c/ping/code/sig_alrm.c:7: undefined reference to `alarm'
/cygdrive/c/EDK/gnu/powerpc-eabi/nt/bin/../lib/gcc/powerpc-eabi/
4.1.1/../../../../powerpc-eabi/lib/libc.a(signalr.o): In function
`_kill_r':
/edkgnu/jade/build/nt/bld_gcc/gcc/newlib/libc/reent/signalr.c:61:
undefined reference to `kill'
collect2: ld returned 1 exit status
make: *** [hello_world/executable.elf] Error 1

Any help with this is greatly appreciated.  Thanks alot!
