Thread: symbol not found in plpgsql.so
I sent an email on this the other day, but didn't see it pop up in the list and there have been no responses, so I don't know if it got through. Sorry if this is a dup. I'm getting the following error when I add a row to a table that has a trigger set for a plpgsql function. I did a nm on the plpgsql.so file and it lists CurrentMemoryContext as being in there, so I don't know why it can't find it. Anyone see anything similar? What do you suggest, a recompile and install? "DBD::Pg::st execute failed: ERROR: Load of file /usr/local/pgsql/lib/plpgsql.so failed: ld.so.1: /usr/local/pgsql/bin/postmaster: fatal: relocation error: file /usr/local/pgsql/lib/plpgsql.so: symbol CurrentMemoryContext: referenced symbol not found" Thanks, Fred Reimer Eclipsys Corporation

No, you're interpreting this backward: the linker is complaining because
it can't find a CurrentMemoryContext symbol in the main program to bind
the .so's reference to.
You didn't say what platform you're on, but on lots of platforms it's
necessary to do something special to ensure that all symbols in a main
program are exported so that dynamically loaded shared libs can see
them. (That's not normally the default behavior because the symbol
table space would be wasted in most programs, which don't do dynamic
loading of random .so files.) On HPUX, for example, the loader has to
be given a -E switch when linking the postgres executable. Dunno what
the incantation is where you live...

Btw., something that has struck me as odd is that the hpux template with the native compiler sets CFLAGS='-Wl,-E -Ae'. I know what the -Ae is for, but the -Wl,-E should probably not be in every compilation command, no? (in particular since LDFLAGS already contains -Wl,-E) -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

Oh, I hadn't noticed that. Yes, that's a waste of time if LDFLAGS has
it.
