The AX_CXX_COMPILE_STDCXX* macros that were embedded in aclocal.m4
have been replaced with the versions found in the autoconf-archive
package from Debian 9.
When generating lists of files with `find`, directories may get output
if you try to prune paths and it has a habit of prefixing paths with a
leading `./`.
The various checks cover all settings in the `.editorconfig` file.
The `--fix` support, however, does not attempt to correct charset
issues because the encoding cannot be determined automatically.
Note that image files as well as generated files in the repository
are exempted from all style checks.
Changes to the test reference files should not, famous last words ;-),
have any effect on the use of the tool's actual outputs.
Note that the tests use a "concocted" `testfile.desc` as their input.
This fixes a [-Wpedantic] compiler warning about ISO C forbidding empty
translation units. The check-usb-chip.c file reduces to such a file in
the case USB support was explicitly disabled or no usable library found.
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.
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 ;-)
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.
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.
