Automake is smart enough these days to compile the *.lo files that are
used when linking.
The umax_pp_CPPFLAGS are useless because backend/umax_pp_low.c undefines
BACKEND_NAME unconditionally and sets it to what was passed here ;-)
Several variables are considered "user variables" by the GNU Standards.
This means that the user can pass these to their ./configure and make
invocations as they see fit. These variables include CPPFLAGS, CFLAGS
and LDFLAGS.
This changeset pushes our use of these variables to the automake shadow
variables, AM_CPPFLAGS, AM_CFLAGS and AM_LDFLAGS, so that user variables
will no longer clobber flags required in order to build.
The AC_SUBST and PKG_CHECK_MODULE invocations in configure.ac as well as
acinclude.m4 are sufficient to trigger automake to insert initialization
logic for the variables these introduce. There is no need to do this by
hand. Wherever these values are needed, it is better to use a variable.
This allows for one-off overrides on the make command-line (without the
need to run ./configure) for one thing.
This addresses warnings about the use of the $(wildcard) function.
It has been replaced by a plain shell glob. There is one case where
this will result in an error, when there are no matches, but that is
when the targets that use it make no sense. It is probably good to
get an error in that case.
with newer automake.
* backend/Makefile.am, tools/sane-config.in: Add missing
$GPHOTO2_LDFLAGS so library can be found.
* tools/Makefile.am: Add mising $SCSI_LIBS to sane-find-scanner.
Add tools/openbsd to distribution package.
* include/Makefile.am: include files should have been installed
under sane/ directory when converted to automake.
* doc/Makefile.am: Cleanup. Use automake's built in support to
install docs within subdirectories.
