When libusb-1.0 is not found, libusb-0.1 will be tried. On BeOS and
OS2, nothing should have changed in terms of detection of USB support.
On all systems the --enable-libusb* flags are now ignored. Instead, the
--with-usb and --without-usb flags now control support. When neither is
given USB support will be enable if possible and disabled otherwise. If
--with-usb is requested but not possible, ./configure will fail. There
is no support to prefer libusb-0.1 over libusb-1.0.
This ought to get rid of the last empty compilation unit warnings. This
merges libfelib.la with liblib.la. The former was always used together
with the latter. The latter was only ever used without the former when
linking backends and tools.
Tools might want to use the getopt functions, backends might just want
to use MD5.
The distclean target should only remove files that make creates. If
there are any that need taking care of, they should be added in on a
per file basis in the Makefile.am that creates it.
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.
Some parts of SANE used __FUNCTION__ while other parts used __func__.
Now, __func__ is used consistently throughout the SANE sources. This
fixes all occurrences of the following GCC warning:
warning: ISO C does not support '__FUNCTION__' predefined identifier
This fixes test failures for release tarballs (pointed out by Mike
Frysinger), clamps down on wildcards and prints a failure message
when a test does not succeed.
Regenerate testsuite reference data which was necessary after these
fixes:
- commit 3b96baef65
"sane-desc: fix udev hwdb generation"
- commit 758731489d
"sane-desc: fix faulty udev logic for SCSI devices"
libusb on my Linux box is returning EACCES error when invalid
permissions exist. Modify open to translate that into
SANE_STATUS_ECCESS_DENIED since that error description is
used for this case.
Modify sanei_usb_test.c to not treat access denied or busy
error codes as real failures since its expected to occur on
boxes that USB device is already claimed by another driver
and if that device uses default root only permissions.
strcmp() does not protect against NULL pointers and is
crashing on at least OS X for the fake devices we are creating
by setting device_number to MAX value.
Add a fake empty string to prevent this.
This lets test pass even when ran from a different location.
Also, added missing data files to distribution list.
These two things lets this test case pass when ran using "make distcheck".
Improving here means do not set LIBS/CFLAGS if library is not detected.
This prevents some unknown options based to ld when host is Linux and
target is mingw32/64. Further improvements are needed if one wants this
snmp support when cross compiling to really work.
Also, to make commit bisectable, updated all autofoo files using
'autoreconf -i -f' and repatching ltmain.sh.
Also, test-driver was missing from git repo but the Makefile.in
checked in expected it to exist.
- fixed a bug in sanei_constrain_value spotted by
viresh_shirol@yahoo.co.uk where range max was exceeded due to rounding
in quantization
- added test case for sane fixed values range
udev now comes with a hardware database (hwdb) which is meant to replace large
rule files as the one typically shipped with sane. This should significantly
speed up the processing of usb add events.
Add the required output format and add a special udev output mode which is
produces the udev file to be used with hwdb.
Sample hwdb file: <https://dev.archlinux.org/~tomegun/20-sane.hwdb>.
Sample udev+hwdb rules file:
<https://dev.archlinux.org/~tomegun/53-sane.rules>.
Similar support was recently added to gphoto2:
<http://sourceforge.net/p/gphoto/code/14490/>.
The new udev rules file does not support old udev/kernels as these anyway
don't support hwdb.
Moreover, it does not come with GROUP=/MODE= or ACL support as this can easily
be done externally by hooking into the libsane_matched envvar. In particular
systemd-logind uses this to do its own ACL handling.
Options were in README but removed at some point. They
are useful so add them back.
Document BACKENDS and PRELOADABLE_BACKENDS variables in
README as well as in configure --help output.
Add check for winsock2.h for socket.h replancement. Also, use this
check to add ws2_32 library. Also, switch all winsock.h references
to winsock2.h.
Add check for getuid and getpass; which are not on mingw.
Add a syslog() replacement that is basically a print(). This
is also used by vsyslog() replacement.
Comment out parts of replacement sigprocmask.c on mingw.
To support these configure.in changes, I need to rebuild all
related files with autoconf 2.68 and libtool 2.4. Hand ported
our sane-backend specific changes to newer ltmain.sh.
resmgr library is only used (optionally) by
sanei_usb and sanei_scsi. So only need to
link it in for those backends. This was
a stray piece from initial cleanup of LIBS
in sane-backends 1.0.20.
