Xcode 不断在错误的路径中搜索 dylib
这是我的错误：
dyld: Library not loaded: /usr/local/lib/libofa.0.dylib
Referenced from: /sers/david/Projekte/Test/build/Debug/Test.app/Contents/MacOS/Test
Reason: image not found
我已经做了一些研究并使用 install_name_tool 更改了 dylib 内的路径：
davids-macbook:Test david$ otool -L libofa.0.0.0.dylib
libofa.0.0.0.dylib:
@executable_path/../Frameworks/libofa.0.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)

/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
但是 Xcode 一直在 /usr/lib/ 中搜索它：
build/Debug/Test.app/Contents/MacOS/Test:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 15.0.0)

有没有办法在 Xcode 中设置它？？？谢谢
编辑：该库不是 Xcode 项目。它使用 ./configure 构建；制作
Thats my error:
dyld: Library not loaded: /usr/local/lib/libofa.0.dylib

I've done some research and changed the path inside the dylib with install_name_tool:
davids-macbook:Test david$ otool -L libofa.0.0.0.dylib
libofa.0.0.0.dylib:
@executable_path/../Frameworks/libofa.0.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.1)
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate (compatibility version 1.0.0, current version 4.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
But Xcode keeps searching for it in /usr/lib/:
build/Debug/Test.app/Contents/MacOS/Test:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 15.0.0)
/System/Library/Frameworks/AudioToolbox.framework/Versions/A/AudioToolbox (compatibility version 1.0.0, current version 1.0.0)
/opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
@executable_path/../Frameworks/TagLib.framework/Versions/A/TagLib (compatibility version 1.0.0, current version 1.0.0)
/System/Library/Frameworks/QTKit.framework/Versions/A/QTKit (compatibility version 1.0.0, current version 1.0.0)
/opt/local/lib/libexpat.1.dylib (compatibility version 7.0.0, current version 7.2.0)
/System/Library/Frameworks/Quartz.framework/Versions/A/Quartz (compatibility version 1.0.0, current version 1.0.0)

/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 1038.32.0)
Is there a way to set this in Xcode??? Thanks
Edit: The library is not a Xcode project. Its build with ./configure; make

通常我会这样做：
@rpath。这会将安装名称设置为@rpath/libofa.0.0.0.dylib。如果您自己构建库，则可以在 Xcode 中进行设置；否则，请使用install_name_tool进行更改。@executable_path/../Frameworks（或@loader_path/../Frameworks）。这篇博文和这个了解更多细节。
Normally what I do is this:
@rpath. This will set the install name to@rpath/libofa.0.0.0.dylib. If you're building the library yourself, you can set this in Xcode; otherwise, useinstall_name_toolto change it.@executable_path/../Frameworks(or@loader_path/../Frameworks).This blog post and this one go into more detail.
确保从developer.apple.com 安装命令行工具，然后将库添加到您的项目中。在 Xcode 中运行以下脚本：目标 » 构建阶段 » 运行脚本并执行：
注意：dylib 名称前不需要 ' 或 ""
Make sure to install the command line tools from developer.apple.com and then add the library in your project. Run the following script in your Xcode: Targets » Build Phases » Run Script and just execute:
Note: NO ' or "" required before dylib name
在寻求解决方案之前，您应该了解 MAC 中的依赖库“dylib”与 Windows 中的依赖库“dll”相比有何新功能。
dylib 与 dll 的主要区别在于“安装名称”。安装名称是嵌入到动态库中的路径，表示运行时在哪里可以找到该库。无论您将 dylib 复制到哪里，它都将始终指向旧路径（除非不更改安装名称）。
您可以使用如下命令
otool -L a.dylib了解原始搜索路径（安装名称） （只需拖动dylib代替a.dylib）
有关安装名称的更多详细信息，请参阅此链接。
现在，更改 dylib("install name") 新位置的解决方案只需使用
install_name_tool如下install_name_tool -change *old path of dylb* *new path of dylib*您可以通过上面描述的
otool -L命令获取旧路径。（旧路径即原始路径）install_name_tool -change也可以更改dylib和可执行文件的搜索路径。您可以通过在项目中的
Run script文件中写入来在 Xcode 中使用它。Before going for solution, you should know what is new with dependent library "dylib" in MAC as compare to dependent library "dll" in windows.
The major difference in dylib vs dll is "install name". The install name is a path baked into the dynamic library that says where to find the library at runtime. It does not matter where you copy your dylibs, It will always point to old path(except without changing install name).
You can know original search path(install name) by using command as below
otool -L a.dylib(just drag dylib in place of a.dylib)
For more detail about install name, refer this link.
Now, solution for changing the new location for dylib("install name") is just use
install_name_toolas belowinstall_name_tool -change *old path of dylb* *new path of dylib*you can get old path by
otool -Lcommand described above already.(old path i.e. original path)install_name_tool -changecan change search path of dylib and executable as well.You can use this in Xcode by writing in
Run scriptfile in your project.
