[mpich-discuss] Segmentation Fault when running any application.

[Michael Warthon]

Ok well I did a bit of searching on past discussions and it looks like the
error will come up but won't affect how the program will run. However, it
seems that I keep getting out of one problem and running into another. When
I tried to compile the hello.c file again I got this error:

/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld: cannot
find
 -lmpi
collect2: ld returned 1 exit status
I want to make sure that other executable will work for mpiexec so I would
like to be able to compile hello.c and then test to see if it will run or
not.
