[mpich-discuss] MPICH2 for ARM

[Harald Schuster]

Hi

I now tried the cpi example from the mpich2 sources and I also got a 
segmentation fault. I used the following configuration:

CFLAGS="-static" CC=arm-linux-gcc ./../configure 
--prefix=/mnt/ti_am1707_root/usr/mpich2-install --with-pm=hydra 
--disable-f77 --disable-fc --disable-cxx --enable-g=dbg,mem,log 
--with-device=ch3:sock --host=arm-linux

How is it possible to trace the execution of the program?!
