I''ve been working on using autoconf and automake to build a project from sources in different subdirectories. I can''t figure out to set extra -I''s for gcc so the toplevel dir is always included. The manuals say i can use the CXXFLAGS/CPPFLAGS or INCLUDES variables, which i have done. The problem is that even though the variables get transferred to the generated makefiles ok, they are given to the compiler. What am i missing? - There is no conspiracy!
