Actually playing with Ashley´s program shown that RTLD_NOW does error
out in the exact same way. So could the problem be that totalview
dlopen´s the plugin with RTLD_NOW passed into dlopen. I would have
thought if this was the case we would have seen this problem sooner.

Anyway, I blame the compiler on this one. As we need the definition of
the ompi_free_list_t structure we have to include the header file. We
never use anything from this header file, especially not the
ompi_free_list functions. However, as one of the functions in the
header file make a reference to the ompi_free_list_grow function
(defined in the .c file), the compiler include a reference to this in
the library.

We are running it with 1.3.2, last I heard - haven't tried the current

that was on the trunk.
My problem is that the library opens but is expecting to find a symbol
in the application that isn't there, it sounds like terry problem is
the
debugger isn't loading the so.
Sounds like we are missing at least a couple of header files.
My first thought for this would be to write a simple C program to
dlopen() the so and see if that works, both with RTLD_NOW and RTLD_LAZY
as I don't know which TotalView uses. Try something like the
following.
#include <dlfcn.h>
int main (argc, argv)
int argc;
char *argv[];
{
void *h;
h = dlopen(argv[1],RTLD_NOW);
printf("Result is %p\n",h);
return 0;
}
