Re: building a c function

[Carsten Kropf <ckropf2@xxxxxxxxx>]

Hello,

I think, what you probably want to do is something like that:

MODULE_big = my_funcs

OBJS = myfunc.o mysubs.o

PG_CONFIG=/usr/local/pgsql/bin/pg_config

PGXS := $(shell $(PG_CONFIG) --pgxs)

include $(PGXS)

Then you will get a shared library called "my_funcs" which includes both of your *.o s and will be deployed to postgres lib dir whenever you call "install" on the makefile.

Best regards

Hello all,

I know this is a very elementary question, but my excuse
is I have not programmed in C or written makefiles for
15+ years...

I am trying to write a C-language function, call it my_func.  
But I also have a my_subs.o that does the heavy lifting
for my_func.c.  My makefile is:

MODULES = my_func
PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
OBJS = my_subs.o # Is this right?

But I see no indication in the output that my_subs.o is
being used:

 gcc -O2 -g ... -fpic -shared -o my_func.so my_func.o

How do I tell the makefile to include my_subs.o when building
the shared lib?
