However, if I want to build in a separate build tree (relying on VPATH), then I try the following:
mkdir /build cd /build /test/configure make
This attempts to build in this new /build directory, but during compilation it cannot locate the header file, myproj.hpp, and the rest of the build fails. What do I need to do in order to tell automake where this header is? I've already tried using the absolute path variables in the Makefile.am:
INCLUDE = -I$(abs_top_srcdir)/project2/sublevel/inc
Note that abs_top_srcdir calculation was broken in Autoconf 2.58. It is fixed in 2.59.
Rather than using INCLUDE you should use AM_CPPFLAGS. For example
AM_CPPFLAGS = -I$(top_srcdir)/project2/sublevel/inc
*g* or override DEFS to let the local includes be found first always... since the days I have had serious problems with includes I do tend to make up projects only ever with a prefix/my.h which needs then only -I$(top_srcdir) where top_srcdir/prefix/ exists. That needs to override the default_includes as well to cut away the -I. -I$(srcdir) settings. Personally, I'd never do myproj.h anymore, only ever now myproj/inc.h
