Hi,
I'm trying to write my first PostgreSQL C extension. I used the
pgxn-utils skeleton as a base and specified some external libraries in
SHLIB_LINK. However, this variable was ignored when linking the
library (using pgxs from current git master).
After spending quite a bit of time trying to understand the Makefile
spaghetti, I noticed that the contrib extensions are using MODULE_big
instead of MODULES. When I converted my makefile, it indeed started
working as expected.
Is there any reason that pgxs ignores SHLIB_LINK when building
MODULES? Seems like a pretty unlikely use case that someone would want
to use MODULE_big and MODULES in the same makefile, so there should to
be no ambiguity -- if SHLIB_LINK is set then it should be used.
This does NOT work:
MODULES = src/pg_journal
SHLIB_LINK = -lsystemd-journal -lsystemd-id128
And this does:
OBJS = src/pg_journal.o
MODULE_big = pg_journal
SHLIB_LINK = -lsystemd-journal -lsystemd-id128
Here's the github repository for this extension:
https://github.com/intgr/pg_journal (the makefile there currently uses
a workaround)
Regards,
Marti
