在Mac OS X上链接库的默认搜索目录是什么？ [英] What are the default search directories to link a library on Mac OS X

问题描述

我已经在Mac OS X上使用CMake构建了 Google Test ，并获得了两个共享库：libgtest.dylib 和 libgtest_main.dylib 。现在我需要安装它们。我知道Linux上有一些默认的搜索目录，例如 / usr / lib ， / usr / local / lib 等。但是我不熟悉Mac OS X并且不知道放置那些图书馆的位置。

在 Mac OS X目录结构，我发现有三个目录库：〜/ Library ， / Library 和 / usr / lib 。我试图将gtest库分别放在这些目录中，只发现 / usr / lib 的作品。

我想知道什么对于 Mac OS X ，默认搜索目录有一些规则，就像在Linux和Windows上一样。

解决方案

查看 dyld 链接器：

< blockquote>

DYLD_FALLBACK_LIBRARY_PATH

    ...

默认情况下，它设置为
$（HOME）/ lib：/ usr / local / lib：/ lib：/ usr / lib

I've build the Google Test with CMake on Mac OS X and get two shared libraries: libgtest.dylib and libgtest_main.dylib. And now I need install both them. I know there are some default search directories on Linux, such as /usr/lib, /usr/local/lib, etc.. But I am unfamiliar with Mac OS X and don't know where to place those libraries.

In Mac OS X Directory Structure, I find there are three directories of libraries: ~/Library, /Library and /usr/lib. And I've tried to place gtest libraries into these directories respectively and found out only /usr/lib works.

What I want to know is wether there are some rules about the default search directories on Mac OS X just like on Linux and Windows.

解决方案

Take a look at the default values for environment variables used by the dyld linker:

DYLD_FALLBACK_LIBRARY_PATH
   ...
By default, it is set to $(HOME)/lib:/usr/local/lib:/lib:/usr/lib
