I'm trying to install a little PostgreSQL addition that I found online. It comes with the following Makefile:
OBJS = pg_prox.o proximity.o ../common/pg_utils.o
MODULE_big = proximity
DATA_built = proximity.sql
DOCS = README.proximity
PGXS := $(shell pg_config --pgxs)
What is the shell
command? I tried it in Ubuntu and FreeBSD without luck. Running web searches on "shell" returns too many pages about shells in general.
