From de739be1299aaa30469fc90ddc0f97ea915c784e Mon Sep 17 00:00:00 2001 From: Daniel Wagner <dwagner@suse.de> Date: Thu, 7 Jul 2022 14:05:49 +0200 Subject: [PATCH v7] libtracefs: Add initial support for meson Introduce Meson as build framework for building libtracefs. The build steps are: # configure using .build as build directory and install destination # /tmp/test meson setup --prefix=/tmp/libtraceevent .build # trigger the build meson compile -C .build # In case you want to build the documentation, trigger the # build via the 'docs' target: meson compile -C build docs # install the library (and documentation) meson install -C .build Signed-off-by: Daniel Wagner <dwagner@suse.de> --- v7: - set default html doc path to share/doc/libtracefs-doc - list libtraceevent in Required pkg-config section. - install (any) man5 pages (keep it in sync with other projects) v6: - changed project defaults to --default-library=both - code style consistency updates - hardening doc install script (shellcheck) - renamed install-man.sh.in to install-docs.sh.in - install-docs.sh.in installs html pages too - introduces docs target - updated copyright year - streamlined documentation meson build file v5: - build unit test only if cunit is found - default build target is debug - do not install man pages into subdirs - install sqlhist (because we install the man page too, so why not the tool?) v4: - add subdir include path to cflags in pkgconfg file - refactoring build instruction for section 1 and section 3 documentation into one loop (reduce code duplication) v3: - build documetation - build samples - set default location to /usr/local v2: - updated commit message - dropped the include path patch, the pkg-config from libtraceevent is including them v1: - initial version Documentation/install-docs.sh.in | 20 ++++ Documentation/meson.build | 197 +++++++++++++++++++++++++++++++ include/meson.build | 11 ++ meson.build | 47 ++++++++ meson_options.txt | 16 +++ samples/extract-example.sh | 3 + samples/meson.build | 45 +++++++ src/meson.build | 63 ++++++++++ utest/meson.build | 17 +++ 9 files changed, 419 insertions(+) create mode 100755 Documentation/install-docs.sh.in create mode 100644 Documentation/meson.build create mode 100644 include/meson.build create mode 100644 meson.build create mode 100644 meson_options.txt create mode 100644 samples/extract-example.sh create mode 100644 samples/meson.build create mode 100644 src/meson.build create mode 100644 utest/meson.build diff --git a/Documentation/install-docs.sh.in b/Documentation/install-docs.sh.in new file mode 100755 index 000000000000..eca9b1f42dcc --- /dev/null +++ b/Documentation/install-docs.sh.in @@ -0,0 +1,20 @@ +#!/bin/bash +# SPDX-License-Identifier: LGPL-2.1 +# +# Copyright (c) 2023 Daniel Wagner, SUSE LLC + +for section in 1 3 5; do + while IFS= read -r -d '' man; do + [ !
