Question

My directory set up:

libone
  one.c
  one.h
  Makefile.am

libtwo
  two.c #includes one.h
  two.h
  Makefile.am

...
Makefile.am
configure.ac
...

Now when I do autoreconf -fvi and configure and make,
I get the error from two.c: could not find one.h.
How do I setup the include paths in Makefile.am’s?
Any help appreciated.

Answer 1

Either do it the quick’n’dirty way

#include "../libone/one.h"

or (preferred, because then it doesn’t matter whether one.h is installed or in the source tree or split out into a different project)

#include <libone/one.h>

and in your Makefile.am

libtwo_a_SOURCES = two.c two.h
libtwo_a_CPPFLAGS = -I$(top_srcdir)
