python: Improve Python detection.

2017-03-22T14:33:06Z

* m4/python.m4 (_AM_PYTHON_INTERPRETER_LIST): Prefer the generic 'pythonX' over 'pythonX.Y'. This way we select the users preferred version for both flavors. Prefer 'python' over 'python3' but not over 'python2' so that the algorithm still finds a 'python2' even if 'python' is a Python3. Fixes-commit: 5189c08af9468cdeb6f16a6ecd0fee53e1e3aa0e Signed-off-by: Justus Winter

build: Tune M4 macros for our needs.

2017-03-14T11:20:18Z

* m4/ax_python_devel.m4: Do not emit 'HAVE_PYTHON'. * m4/python.m4 (_AM_PYTHON_INTERPRETER_LIST): Add newer Python versions, drop older ones. Also, sort the list with older versions at the front, newer and generic versions towards the end. This makes the algorithm pick the lowest version that meets the version requirement.

build: Add M4 macros for python.

Qt: Make sure extended grep is used with '|'.

2016-12-19T09:36:17Z

* m4/qt.m4: Use grep -E when using the alternation character. -- POSIX specifies '|' is only supposed to work as an alternation special character when grep is used in extended mode. The code worked fine with GNU grep because it accepts extended regular expressions by default, but other POSIX-compliant implementations might fail and take it literally.

python: Improve build system integration.

* configure.ac: Try to compile a Python module for each version. * m4/m4_ax_swig_python.m4: Drop unused file. Signed-off-by: Justus Winter

m4: Don't set fpic for qt on windows

2016-07-12T13:26:14Z

* m4/qt.m4 (FIND_QT): Do not set fpic for windows. -- Otherwise each compile call will result in a warning that fpic is ignored for windows.

m4: Use LIBS instead of LDFLAGS for Qt libs

2016-07-12T13:10:16Z

* m4/qt.m4: Modify LIBS instead of LDFLAGS for link test. -- The test would otherwise fail when building for windows because the link order was wrong.

m4: Add compile / link check for qt

2016-07-11T16:48:42Z

* m4/qt.m4 (FIND_QT): Check if a qt application can be compiled and linked. -- In case gpgme is cross compiled pkg-config may pick up qt for the build system and not for the host system. To avoid that we check that we can compile a qt program for host.

python: Make Python detection more robust.

2016-06-01T13:33:52Z

Previously, missing Python development packages made configure fail instead of merely disabling the bindings. * configure.ac: Check for 'PYTHON_VERSION'. * m4/ax_python_devel.m4: Make test non-fatal. Signed-off-by: Justus Winter
