More on shared objects problem

Many thanks to everyone who helped so far especially Todd Vierling for
the RTFF. I think I am closer but I still have a problem. Here is the
rule in my makefile now.

.o.so:
ld -shared -L${PGDIR}/lib --export-dynamic -rpath ${PGDIR}/lib \
-lpq -lc -o $@ $<

ldd now shows this.

glaccount.so:
-lpq => /usr/pgsql/lib/libpq.so
-lc.12 => /usr/lib/libc.so.12

I then went into the PostgreSQL code and added a dlerror() call to the
error message after dlopen(). I still get an error but now I get a little
more information.

ERROR: Load of file /usr/pgsql/modules/glaccount.so failed: dlopen (/usr/pgsql/modules/glaccount.so) failed (/usr/pgsql/modules/glaccount.so: Undefined symbol "CurrentMemoryContext" (reloc type = 6, symnum = 6))

CurrentMemoryContext is defined in the postmaster (I checked with nm) which
is the program doing the dlopen. Here is the relevant line from nm.

08138544 D CurrentMemoryContext

So it looks like everything should be working but it doesn't. Is this
possibly a case of bogus error message or am I misunderstanding it? Is
ELF fully baked or do I need to revert to a pre-ELF system?

Hmm. I just noticed that nm is an old binary and that it doesn't build
from current sources due to a missing bfd.h. Is nm like ldconfig and
not needed any more on ELF systems or is there just a problem with
the current sources?
