Tom, Not sure what you mean by "oid" system:
[postgres@dev1 lib]$ uname -a Linux dev1 2.6.35.14-106.fc14.x86_64 #1 SMP Wed Nov 23 13:07:52 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux [postgres@dev1 lib]$ ldd bar.so linux-vdso.so.1 => (0x00007fff1c7ff000) libc.so.6 => /lib64/libc.so.6 (0x00007fa4c96ac000) /lib64/ld-linux-x86-64.so.2 (0x00007fa4c9c5d000) pinguinito:~/sandbox/postgresql-9.2.4 sscheck$ head -10 config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by PostgreSQL configure 9.2.4, which was generated by GNU Autoconf 2.63. Invocation command line was $ ./configure --prefix=/home/sscheck/sandbox/postgresql-9.2.4-build --enable-debug CFLAGS=-O0 You'll have to bear with me, I'm not well versed in the subtleties of rpath, shared vs. static linking, etc. (actually almost completely ignorant). Looking at configure help though "--disable-rpath" is not present... After digging into the PGXS docs a bit more, I think if I change the Makefile a bit this may work: MODULES = foo bar MODULE_big = bar OBJS = bar.o SHLIB_LINK = foo.o Thanks for taking a look at this. -Steve On Wed, Jun 12, 2013 at 8:08 PM, Tom Lane <t...@sss.pgh.pa.us> wrote: > Stephen Scheck <singularsyn...@gmail.com> writes: > > However, whenever I run one of the UDTs defined in bar, I get this error > > message: > > > dev=# SELECT * FROM test1 WHERE (info(bar_dat)).some_prop = 10; > > ERROR: could not load library > > "/vol/data/home/postgres/pg-builds/9.2.4/lib/bar.so": > > /vol/data/home/postgres/pg-builds/9.2.4/lib/bar.so: undefined symbol: > > foo_func1 > > I'm betting an rpath problem.
