[Beowulf] Re: static pvm library won't link anymore

[David Mathog]

Turns out that the difficulties getting pvm to run were not just
pvm problems.  There is a bizarre problem where every program, even
"Hello World" built on Mandriva 2007.1 (gcc 4.1.2,2.6.17-14mdv) 
will not run on Mandriva 2007.0 (gcc 4.1.1, 2.6.19.3).  Going
in the other direction works, as does Mandriva 2006.0 to either,
and of course all programs run wherever they were built
in the first place.  Here's hello refusing to run on 2007.0 under gdb:

(master)
# cat hello.c
#include <stdio.h>
int main(void){
  (void) fprintf(stdout,"HELLO\n");
}
# gcc -g -o hello hello.c
# hello
HELLO
# cp hello /usr/common/bin

(slave)
# gdb /usr/common/tmp/hello

The program is running.  Exit anyway? (y or n) y

When the master node was upgraded a short time ago from Mandriva 2006.0
to 2007.1 it introduced this problem, but it didn't manifest until the
first time a program was built on the master and distributed to the
slaves, and that was, unfortunately, pvm, which has enough build issues,
that it took a while to determine that this was yet _another_ issue
beyond those.
