Here are the results.

pkg-config --c= flags --libs gsl yields:
-lgsl -lgslcblas -lm

pkg-config --cflags= --libs ncurses yields:
-D_GNU_SOURCE -lncurses -ltinfo

Doe= s this look good?

Try e.g. "pkg-co= nfig --cflags --libs gsl".=C2=A0 You can then test whether
the returned flags are good for compiling + linking a test application
in C.
