I was doing a test where I am using GNU automake and autoconf. I have a directory structure such as:
/test Makefile.am configure.in /test/project1 Makefile.am /test/project1/sublevel Makefile.am /test/project1/sublevel/src myproj.cpp Makefile.am /test/project1/sublevel/inc myproj.hpp The contents of /test/project1/sublevel/src/Makefile.am is: INCLUDE = -I../inc lib_LIBRARIES = libmyproj.a libmyproj_a_SOURCES = myproj.cpp myproj.hpp So this works alright if I am building within the source tree (i.e. myproj.a is built in /test/project1/sublevel/src). 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 This doesn't seem to help. Thanks, John
