build: Always compile the Qt 6 test application with -fpic

2022-10-13T13:39:29Z

* m4/qt6.m4: Do not add -fpic to GPGME_QT6_CFLAGS. Add -fpic to CPPFLAGS used for build test of simple Qt 6 application. -- The pkgconfig files of Qt6Core do not contain the qt_config variable, so that we cannot easily check whether Qt6 was compiled with pic. For simplicity we always compile the test application with -fpic to avoid a build failure if Qt6 was actually compiled with pic. For the actual build of QGpgME libtool automatically uses -fPIC, so that we don't have to add it to the GPGME_QT6_CFLAGS.

build,qt: Allow building QGpgME for Qt 6

2022-10-11T09:00:14Z

* configure.ac: Look for Qt 5 and/or Qt 6. Require C++17 if Qt 6 binding is built. Build cmake files QGpgmeConfig* for Qt 5 and QGpgmeQt6Config* for Qt 6. (available_languages): Add "qt5" and "qt6". (WANT_QT5, WANT_QT6): New conditionals. * lang/qt/src/Makefile.am: Keep building libqgpgme for Qt 5. Build libqgpgmeqt6 for Qt 6. * lang/qt/tests/Makefile.am: Build tests for Qt 5 or Qt 6. * lang/qt/src/QGpgmeQt6Config-w32.cmake.in.in, lang/qt/src/QGpgmeQt6Config.cmake.in.in, lang/qt/src/QGpgmeQt6ConfigVersion.cmake.in, m4/qt6.m4: New. -- This makes it possible to build QGpgME optionally for Qt 6.4.0 or later. By default or if the language "qt" is enabled, then QGpgME is built either for Qt 5 (if found) or Qt 6. A build for Qt 5 or Qt 6 can be requested by explicitly enabling the language "qt5" or "qt6". Building QGpgME for Qt 5 and Qt 6 simultaneously is not supported.

build,qt: Explicitly namespace a few Qt variables for Qt5

2022-10-10T12:46:39Z

m4/qt.m4: Rename to m4/qt5.m4: this. (FIND_QT): Rename to FIND_QT5. (GPGME_QT): Change variable prefix to GPGME_QT5. (GPGME_QTTEST: Change variable prefix to GPGME_QT5TEST. configure.ac, lang/qt/src/Makefile.am, lang/qt/tests/Makefile.am: Adjust accordingly. -- In preparation to adding support for building qgpgme for Qt6, add the version number to a few variables to avoid confusion.

build: Update ax_cxx_compile_stdcxx macro

2022-08-22T13:04:32Z

* m4/ax_cxx_compile_stdcxx.m4: Replace with current version from the autoconf archive. -- This fixes the problem that the switch -std=c++11 was omitted if the compiler supported C++11 features by default. This made gcc happily compile C++14 code. Now C++11 is enforced by gcc. GnuPG-bug-id: 6141

build: Fix for modern Autoconf.

2022-07-21T04:47:06Z

* m4/glib-2.0.m4: Use AC_RUN_IFELSE and AC_LINK_IFELSE. -- Signed-off-by: NIIBE Yutaka

build: Update gpg-error.m4

2022-06-28T02:28:06Z

* m4/gpg-error.m4: Update from libgpg-error. -- Signed-off-by: NIIBE Yutaka

cpp: Set default visibility of all symbols to hidden

2022-03-28T15:22:48Z

* configure.ac: Add -fvisibility=hidden to GPGME_CPP_CFLAGS if gcc supports the flag. * lang/cpp/src/Makefile.am (AM_CPPFLAGS): Add GPGME_CPP_CFLAGS. * m4/ax_gcc_func_attribute.m4: New. -- With this change all defined symbols are hidden by default, so that they are not exported anymore. All symbols that are part of the ABI and that shall still be exported are already marked as having default visibility. The m4 macro was taken from the website mentioned in the License header of the file. GnuPG-bug-id: 5906

libtool: Link without -flat_namespace for macOS.

2021-11-10T02:06:34Z

* m4/libtool.m4: Not setting 10.0 to MACOSX_DEPLOYMENT_TARGET when not defined. Only specify -flat_namespace to linker for specific (older) versions and hosts. -- Original patch was by: Jeremy Huddleston Sequoia in https://lists.gnu.org/archive/html/libtool-patches/ 2020-06/msg00001.html Reported-by: Aleix Conchillo Flaque GnuPG-bug-id: 5610 Signed-off-by: NIIBE Yutaka

build: Update gpg-error.m4

2021-05-27T04:35:38Z

* m4/gpg-error.m4: Update from libgpg-error. -- Signed-off-by: NIIBE Yutaka

build: Update with newer autoconf constructs.

2020-11-18T05:34:52Z

* configure.ac: Use AC_USE_SYSTEM_EXTENSIONS instead of AC_GNU_SOURCE. Use AS_HELP_STRING instead of AC_HELP_STRING. * m4/libtool.m4: Update from libgpg-error. * m4/gpg-error.m4: Update from libgpg-error. * m4/libassuan.m4: Update from libassuan. Signed-off-by: NIIBE Yutaka
