我正在构建一个包含 gtk 和 libhandy 库的应用程序。我正在尝试将 libhandy 捆绑到我的项目中。我正在使用介子构建系统。要将依赖项添加到介子,我已从此处遵循以下文档1

我已将 libhandy 库克隆到我的项目中,project_root/subprojects/libhandy/ 这是我的project_root/meson.build文件

project('githandytest', 'c',
          version: '0.1.0',
    meson_version: '>= 0.50.0',
  default_options: [ 'warning_level=2',
                     'c_std=gnu11',
                   ],
)

libhandy_dep = dependency('libhandy-0.0', version: '>= 0.0.13')
if not libhandy_dep.found()
  libhandy = subproject(
    'libhandy',
    install: false,
    default_options: [
      'examples=false',
      'package_subdir=my-project-name',
      'tests=false',
    ]
  )
  libhandy_dep = libhandy.get_variable('libhandy_dep')
endif

i18n = import('i18n')

config_h = configuration_data()
config_h.set_quoted('PACKAGE_VERSION', meson.project_version())
config_h.set_quoted('GETTEXT_PACKAGE', 'githandytest')
config_h.set_quoted('LOCALEDIR', join_paths(get_option('prefix'), get_option('localedir')))
configure_file(
  output: 'githandytest-config.h',
  configuration: config_h,
)
add_project_arguments([
  '-I' + meson.build_root(),
], language: 'c')


subdir('data')
subdir('src')
subdir('po')
subdir('subprojects')

meson.add_install_script('build-aux/meson/postinstall.py')

我包含的文件<libhandy.h>是 main.c,位于project_root/src Here 是project_root/src/meson.build

githandytest_sources = [
  'main.c'
]

githandytest_deps = [
  dependency('gio-2.0', version: '>= 2.50'),
  dependency('gtk+-3.0', version: '>= 3.22'),
  dependency('libhandy-0.0')
]

gnome = import('gnome')

executable('githandytest', githandytest_sources,
  dependencies: githandytest_deps,
  install: true,
)

自从我使用 flatpak 分发以来,我还向项目清单添加了源代码。

{
    "app-id" : "org.example.App",
    "runtime" : "org.gnome.Platform",
    "runtime-version" : "3.38",
    "sdk" : "org.gnome.Sdk",
    "command" : "githandytest",
    "finish-args" : [
        "--share=network",
        "--share=ipc",
        "--socket=fallback-x11",
        "--socket=wayland"
    ],
    "cleanup" : [
        "/include",
        "/lib/pkgconfig",
        "/man",
        "/share/doc",
        "/share/gtk-doc",
        "/share/man",
        "/share/pkgconfig",
        "*.la",
        "*.a"
    ],
    "modules" : [
        {
            "name" : "githandytest",
            "builddir" : true,
            "buildsystem" : "meson",
            "sources" : [
                {
                    "type" : "git",
                    "url" : "file:///home/davtyan/Projects/githandytest"
                }
            ]
        },
        {
      "name" : "libhandy",
      "buildsystem" : "meson",
      "builddir" : true,
      "config-opts": [
        "-Dexamples=false",
        "-Dtests=false"
      ],
      "sources" : [
        {
          "type" : "git",
          "url" : "https://source.puri.sm/Librem5/libhandy.git"
        }
      ]
    }
    ]
}

我在运行项目时遇到的问题是:project_root/meson.build:9:0: ERROR: Dependency "libhandy-0.0" not found, tried pkgconfig and cmake

我为这样一个模糊的问题道歉。我对介子构建系统非常陌生,无法完全弄清楚为什么会发生这种情况。如果有帮助,我正在使用 gnome-builder IDE。

看起来您不需要第二次创建依赖对象dependency('libhandy-0.0')并使用已创建的:

githandytest_deps = [
  dependency('gio-2.0', version: '>= 2.50'),
  dependency('gtk+-3.0', version: '>= 3.22'),
  libhandy_dep
]

我的意思是你有这个错误,因为它试图找到(使用 pkg-config)这个依赖而不是查看你对libhandy_dep的评估。

但是,请注意,可以通过以下方式简化此依赖项(pkg-config + 子项目)的评估:

libhandy_dep = dependency('libhandy-0.0', version: '>= 0.0.13', 
             fallback : ['libhandy', 'libhandy_dep'],
             default_options: ['examples=false', 'package_subdir=my-project-name', 'tests=false'])

文档开始:

['subproj_name', 'subproj_dep'],第一个值是子项目的名称,第二个是该子项目中包含依赖对象的变量名,例如declare_dependency或dependency()的返回值,
