Hi there,
I have a problem due to conflicts between local and system header
filenames. This problem comes about because of the addition of -I. to
the CXXFLAGS of any objects. I've traced this to a variable called
DEFAULT_INCLUDES in every Makefile.in:
DEFAULT_INCLUDES = -...@am__isrc@ -I$(top_builddir)
Why does this -I. exist? How can I remove it?
DEFAULT_INCLUDES actually resolves to:
DEFAULT_INCLUDES = -I. -I$(srcdir) -I$(top_builddir)
That is, the current directory, the source directory (if building
outside the source tree), and the top build directory (in order to pick
up config.h or other project-global headers.
It is assumed that there would be no header files in the current or
source directory that are not *more* important (and should thus be
picked up first) than any other header files outside the project.
Just curious - under what conditions do you have a header file in the
local directory that you need to have overridden by a globally installed
header file?

John
