如何链接到/usr/local/lib上的libc ++? [英] How to link to libc++ on /usr/local/lib?

问题描述

我尝试提供-L /usr/local/lib，尝试-nostdinc++，尝试设置DYLD_LIBRARY_PATH和DYLD_FALLBACK_LIBRARY_PATH，但是otool离开给了我:

I've tried to provide -L /usr/local/lib, tried -nostdinc++, tried to set DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH but otool aways gives me:

otool -L sample
sample:
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

如何链接到我在OS X上自定义编译的/usr/local/lib/libc++.dylib?

How to link to my custom compiled /usr/local/lib/libc++.dylib on OS X?

编译的变化基于基本的clang++ -std=c++11 -stdlib=libc++.

Variations of compilation were upon basic clang++ -std=c++11 -stdlib=libc++.

推荐答案

正如您所指出的，带有-L的oTool告诉您正在/usr/lib中使用libc ++.1.dylib.

As you've pointed out, oTool with -L is telling you that the libc++.1.dylib is being used from /usr/lib.

OSX开发为您提供了* install_name_tool *命令，该命令使您可以设置所需路径的位置.

OSX development provides you with the command *install_name_tool*, which allows you to set the location of the required paths.

作为示例，您将使用如下所示的内容:-

As an example, you'd use it something like this: -

install_name_tool -change /usr/lib/libc++.1.dylib /usr/local/lib/libc++.dylib <target file>

第一个路径是当前路径，第二个是您要将其更改为的路径，第三个是您要为其更改路径的文件.

where the first path is the current path, the second is the one you want to change it to and the third is the file you're changing the paths for.
