问题描述
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,我遵循了此处的以下文档 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 <libhandy.h>
的文件是位于 project_root/src
的 main.c
这是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,)
由于我使用 flatpak 进行分发,因此我还向项目清单添加了源。
{
"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","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
对于这么含糊的问题,我深表歉意。我对介子构建系统非常陌生,无法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。
解决方法
看起来不需要第二次创建依赖对象dependency('libhandy-0.0')
并使用已经创建的:
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,此依赖项(pkg-config + 子项目)的评估可以简化为:
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'])
自 docs 起:
['subproj_name','subproj_dep'],第一个值是 子项目,第二个是该子项目中的变量名称 包含一个依赖对象,如返回值 声明依赖或依赖(),
