Hi I have written a number of C-Function which compile and link against the GNU Scientific Library libraries 'libgsl' and 'libgslcblas' when using a hand written Makefile, but I would like to use PGXS. My functions compile fine using PGXS, but don't link against the GSL libraries. How do I specify the GSL libraries as external libraries to link against in the PGXS Makfile? I have tried the following which don't work: PG_CPPFLAGS = -lgsl -lgslcblas PG_LIBS = -lgsl -gslcblas SHLIB_LINK = -lgsl -gslcblas My PGXS makefile is: MODULES pg_gsl PGXS := $(shell $(PG_CONFIG) --pgxs) include $(PGXS) Many thanks John
