[Llvm-bgq-discuss] Error With Dynamic Linking on Mira Head Node

[Derek Gaston]

Having trouble getting a dynamically linked executable working on
Mira/Cetus head nodes.  The executable _is_ working if I submit it to the
queue.

Compiling a static executable works both on the head node and on the
compute nodes.

Is there some special environment sauce I need that will enable me to run
these executables on the head node?  Obviously I don't want to run much on
the head node... but not even being able to test the executables without a
trip through the queue is problematic!  For instance... "configure" scripts
kind of rely on being able to compile/run simple test programs!

My .soft is:

+mpiwrapper-bgclang-mpi3.legacy.ndebug
@default

(Note: I have also tried essentially all the other bgclang options and they
all produce the same error).


I'm trying to compile a test.c:

int main()
{
  return 0;
}

My compile line is:

mpicc -o test -dynamic test.c


The error I'm seeing is:

$ ./test
ERROR: ld.so: object '/soft/buildtools/trackdeps/${LIB}/trackdeps.so' from
LD_PRELOAD cannot be preloaded: ignored.

Getting a stack trace out of the core file gives:

Thanks for any help!
