dyld:未加载库...原因:未找到图像 [英] dyld: Library not loaded ... Reason: Image not found

问题描述

在尝试运行我在Mac OS X中发送的可执行文件时，出现以下错误

When trying to run an executable I've been sent in Mac OS X, I get the following error

dyld: Library not loaded: libboost_atomic.dylib
  Referenced from: /Users/"Directory my executable is in"
  Reason: image not found
Trace/BPT trap:5

我已经安装了boost库，它们位于/opt/local/lib中.我认为问题仅与可执行文件有关，因为当我在其中粘贴"libboost_atomic.dylib"时，就不再关心它了.不幸的是，然后它抱怨找不到下一个增强库.

I have installed the boost libraries and they are located in /opt/local/lib. I think the problem has something to do with the executable only looking in the directory it is in as when I paste the 'libboost_atomic.dylib' in there, it doesn't mind about it anymore. Unfortunately then it complains it can't find the next boost library.

有一种简单的方法可以解决此问题吗?

Is there an easy way to fix this?

推荐答案

查找所有增强库:

$ otool -L exefile
exefile:
        @executable_path/libboost_something.dylib (compatibility version 0.7.0, current version 0.7.0)
        /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 65.1.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

，然后对每个libboost_xxx.dylib执行:

$ install_name_tool -change @executable_path/libboost_something.dylib /opt/local/lib/libboost_something.dylib exefile

，最后再次使用otool进行验证:

and finally verify using otool again:

$ otool -L exefile
exefile:
        /opt/local/lib/libboost_something.dylib (compatibility version 0.7.0, current version 0.7.0)
        /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 65.1.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

编辑前一段时间，我编写了python脚本(copy_dylibs.py)，以便在构建应用程序时自动计算所有这些内容.它将把/usr/local或/opt/local中的所有库打包到应用程序捆绑包中，并修复对这些库的引用以使用@rpath.这意味着您可以使用Homebrew轻松安装第三方库并打包它们.

EDIT A while back I wrote a python script (copy_dylibs.py) to work out all this stuff automatically when building an app. It will package up all libraries from /usr/local or /opt/local into the app bundle and fix references to those libraries to use @rpath. This means you can easily install third-party library using Homebrew and package them just as easily.

我现在已经在 github 上将此脚本公开.

I have now made this script public on github.
