在 Xcode C++ 项目中链接外部库 [英] Link External Library in Xcode C++ Project

问题描述

我已经找到了这个问题的答案，但它们对我不起作用.我正在尝试在 Xcode 中构建一个 C++ 项目，该项目使用来自 ffmpeg 和 openCV 的外部库，但我不知道如何链接它们.按照建议，我转到构建阶段"屏幕，那里有一个将二进制文件与库链接"的位置.我需要链接的库之一位于/usr/local/lib/libavutil.a.当我尝试添加库时，会弹出一个列表框，显示两个文件夹:OS X 10.11"和Developer Frameworks".我需要的库不在这两个文件夹中.我尝试单击添加其他"并出现一个文件选择器对话框，但是如果我在搜索框中键入/usr/local/lib/libavutil.a"，该对话框不接受它.

I've found answers to this question, but they don't work for me. I'm trying to build a C++ project in Xcode that uses external libraries from ffmpeg and openCV, and I can't figure out how to link them. As recommended, I go the "Build Phases" screen, and there's a place for "Link Binary with Libraries." One of the libraries I need to link with is at /usr/local/lib/libavutil.a. When I try to add a library, a list box pops up showing two folders: "OS X 10.11" and "Developer Frameworks". The library I need is not in either of these folders. I tried clicking on "Add Other" and a file chooser dialog comes up, but if I type "/usr/local/lib/libavutil.a" in the search box, the dialog doesn't accept it.

我发现在Build Settings"中的Other linker flags"行输入-lswcale -lavcodec -lavdecice"等是有效的，但这不是我所希望的.我希望得到一个文件选择器对话框，我可以在其中简单地单击我想要使用的库.

I've found that typing '-lswcale -lavcodec -lavdecice' etc. on the "Other linker flags" line in "Build Settings" works, but it's not what I hoped for. I was hoping to get a file chooser dialog, where I could simply click on the libraries I want to use.

有没有办法实现我想要的?

Is there a way to accomplish what I want?

推荐答案

如果我理解您的要求，您只是想在正确的位置设置"文件选择器对话框，对吗?

If I understand correctly what you are asking, you simply want to "set" the file chooser dialog at the right place, right?

如果是这样，您只需在进入文件选择器对话框后按 Cmd + Alt + G，然后单击链接二进制文件与库"中的添加其他..."菜单.将出现转到文件夹:"对话框，您可以在其中键入文件或要查找的文件夹的完整路径.

If so, you just have to press Cmd + Alt + G once you are in the file chooser dialog, after clicking on "Add Other..." in the "Link Binary with Libraries" menu. A "Go to the folder:" dialog comes up, and there you can type the fullpath to the file or the folder you are looking for.
