使用 Ninja

如何解决使用 Ninja

上下文：2011 年年中 iMac、MacOS High Sierra 10.13.6、鱼终端

所以，我正在尝试构建一个应用程序，并且到目前为止我已经遵循了开发人员提供的清单。满足所有依赖关系，否则运行 Meson 将无法正常工作。开发人员说“运行 ninja -C build 或 ninja -C build install 以安装应用程序。”

我这样做了，但立即失败了。 12 错误。我认为都与 OpenGL 相关。

它在第二行代码中失败了。以下是来自 ../Engine/Engine.vala

的片段

using SDL;
using GL;

namespace Engine
{
    public abstract class Engine : Object
    {
        Engine(bool multithread_rendering,string version_string,bool debug)
        {
            this.multithread_rendering = multithread_rendering;
            this.debug = debug;
            this.version_string = version_string;
        }

还有很多，但这可能并不重要，因为它在第 2 行失败了。

现在，我对 Vala 一无所知，也不知道它是如何工作的，但根据我有限的知识，这似乎是 Vala 无法找到它要找的东西的问题。

我一直在往墙上扔东西，但没有任何东西被卡住。任何建议或指示将不胜感激

编辑 (6/7/21) 我被要求提供用于构建的 meson.build 的内容，所以这里是

project('OpenRiichi','vala','c')

# We use subdir instead of subproject so we don't have to recompile everything when we change something in libengine
subdir('Engine')

dataDir = get_option('prefix') / get_option('datadir') / 'OpenRiichi'

dependencies = [
    valac.find_library('os',dirs: meson.current_source_dir() + '/vapi',required: false)

includes = [include_directories('include'),engine_includes]

executable('OpenRiichi',sources,dependencies: dependencies,include_directories: includes,gui_app: true,install: true
)
install_subdir('bin/Data',install_dir: dataDir)

我会调查相关问题，并自己做一些更多的挖掘，但现在它不再在黑暗中摸索了，所以谢谢。

编辑 2 6/7/21：

查看 meson.build 我看到了这一行，

if target_machine.system() == 'windows'
    engine_dependencies += cc.find_library('opengl32')
    engine_dependencies += valac.find_library('gl',dirs: engine_vapi_dir)
else
    engine_dependencies += dependency('gl')
endif

这可能是罪魁祸首，因为我记得在某处读到 OpenGl 作为对 MacOS 的依赖不是“GL”而是“OpenGL”，或者后者带有一些版本号。我会沿着这条路走下去，看看它会把我引向何方。
