Re: [libvirt] [dbus PATCH v2] build: convert to Meson/Ninja build system

Meson build system is simple and quick compared to Autotools and it's able to fully replace our Autotools usage. There are few drawbacks as it's a fairly new build system, it requires Python 3.5 and Ninja 1.5.0, it's still evolving and the user base is not that large and there were some tweaks required to achieve the same functionality. However, there are benefits, the configure and build time is way shorter and build definition files are more readable and easier to maintain. There are some major changes with Meson build system: - there is no syntax-check target, the syntax-check is part of Meson test suite but it's still possible to run it separately, - Meson forces separation between source and build directories Signed-off-by: Pavel Hrdina <phrdina(a)redhat.com&gt; Tested-by: Ján Tomko <jtomko(a)redhat.com&gt; --- Notes: changes in v2: - add -Werror if we are building from git - fixed -Wframe-larger-than - removed unrelated fix - added comment for flake8 ignore warning - added 'suite' labels 'syntax' and 'unit' for tests - AUTHORS and libvirt-dbus.spec are generated only when building from git - run.in is no longer executable, there is a helper script to fix permissions for the generated run script - fixed include_directories for test executable, direct paths can be used since meson 0.50.0 - flake8 is optional as it was with autotools - added meson version into spec file .gitignore | 1 + AUTHORS.in | 2 +- HACKING.md | 24 ++-- Makefile.am | 51 ------- README.md | 12 +- autogen.sh | 52 ------- configure.ac | 87 ----------- data/Makefile.am | 83 ----------- data/meson.build | 15 ++ data/session/meson.build | 6 + data/system/meson.build | 18 +++ docs/Makefile.am | 21 --- docs/meson.build | 8 ++ libvirt-dbus.spec.in | 9 +- m4/manywarnings.m4 | 276 ----------------------------------- m4/virt-arg.m4 | 154 -------------------- m4/virt-compile-pie.m4 | 35 ----- m4/virt-compile-warnings.m4 | 203 -------------------------- m4/virt-linker-relro.m4 | 35 ----- m4/warnings.m4 | 79 ---------- meson.build | 279 ++++++++++++++++++++++++++++++++++++ meson_options.txt | 6 + run.in | 4 +- src/Makefile.am | 66 --------- src/meson.build | 42 ++++++ tests/Makefile.am | 57 -------- tests/meson.build | 52 +++++++ tools/fix-perm.sh | 3 + tools/gen-authors.sh | 4 + 29 files changed, 463 insertions(+), 1221 deletions(-) delete mode 100644 Makefile.am delete mode 100755 autogen.sh delete mode 100644 configure.ac delete mode 100644 data/Makefile.am create mode 100644 data/meson.build create mode 100644 data/session/meson.build create mode 100644 data/system/meson.build delete mode 100644 docs/Makefile.am create mode 100644 docs/meson.build delete mode 100644 m4/manywarnings.m4 delete mode 100644 m4/virt-arg.m4 delete mode 100644 m4/virt-compile-pie.m4 delete mode 100644 m4/virt-compile-warnings.m4 delete mode 100644 m4/virt-linker-relro.m4 delete mode 100644 m4/warnings.m4 create mode 100644 meson.build create mode 100644 meson_options.txt delete mode 100644 src/Makefile.am create mode 100644 src/meson.build delete mode 100644 tests/Makefile.am create mode 100644 tests/meson.build create mode 100755 tools/fix-perm.sh create mode 100755 tools/gen-authors.sh
