These are courtesy of autopoint and target gettext-0.18.1 because that
is the version in Debian 7 (which is what Alioth is running). The one
warning this produces on autoreconf is fixed in gettext-0.18.2, BTW.
The idea is to build as much as possible for the *-full flavour build,
make compiler warnings stand out and muddle on after errors so that we
get all the problems in a single log.
Upon re-reading the autoconf documentation, this seemed the right thing
to do. The AC_LANG_PROGRAM macro does not quote its arguments so any
occurence of [ and ] will get stripped out if not double quoted.
Current code snippets passed do not use them but it is better to use a
consistent quoting approach for such snippets. In other places in the
configure.ac file double quoting is used already.
This gets rid of a number of obsoleted macros and replaces RETSIGTYPE
with a void literal which can be assumed for C89 and later.
This changeset was prepared using autoupdate and modified to get rid of
whitespace and doubled [] changes. Changes to acinclude.m4 were added
by hand.
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It has been replaced by a plain shell glob.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.
This addresses autoreconf output such as:
tools/Makefile.am:37: warning: source file '../backend/sane_strstatus.c' is in a subdirectory,
tools/Makefile.am:37: but option 'subdir-objects' is disabled
The option was introduced in automake version 1.9 and is slated for
unconditional activation with automake-2.0.
This name has been preferred since autoconf-2.52 and automake-1.5.
Both were released in the summer of 2001. Support for configure.in
is slated for removal in automake-2.0.
The configure.ac file itself requires autoconf-2.54 or later (and
does not care about the automake version).
- hide compression-arg option when jpeg disabled
- add Send/SC/GHS macros for recent scanners
- add initial support for fi-74x0
- add initial support for fi-7030
- set has_MS_lamp=0 for fi-71x0
- add I18N macros to all option titles and descriptions
- add usb ids for many newer scanners
Patch is submitted by Laxmeesh Onkar Markod <m.laxmeesh@samsung.com>
Patch to code is applied almost verbatim, except, insignificant
formatting fixes and making new functions static.
Also, new USB ids added and scanner support is changed as reported.
