qt mac osx 10.8 dyld：库未加载...未找到图像

Question

我有一个应用程序，我正在使用Qt 4.7.4在osx雪豹下构建并运行良好，但该macbook已经死了。我现在正在建立一个运行山狮（10.8.2）和Qt 4.8.3的新macbook。我可以构建我的应用程序，但是当我尝试在Qt Creator 2.6.0中运行它时，我得到此运行时错误：

dyld: Library not loaded: ../lib/libicudata.46.1.dylib
  Referenced from: /Users/david/dev/svn/map_creator/karte-build-Desktop-Debug/debug/MapCreator.app/Contents/MacOS/MapCreator
  Reason: image not found
The program has unexpectedly finished.

我从Finder运行它时遇到类似的错误。

otool给了我：

    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 744.12.0)

是什么东西从雪豹到山狮，或从Qt 4.7.4到4.8.3，这导致了这个问题？或者也许我错过了在我的新Macbook上设置所有内容的步骤？我还在学习 - 真的只是Qt和Mac的新手，试图在主要开发人员离开后维护这个项目。

谢谢，大卫

在Qt项目设置中，在运行时设置下，您必须添加已编译的ICU库的路径。有一个网格，您可以在其中设置环境变量等。您需要的是DYLD_LIBRARY_PATH，并设置（或追加）ICU库的路径。

这将使Qt能够将../lib/libicudata.46.1.dylib解析为实际的库文件。

Answer 2

Qt 5.2.0脱机安装程序中存在一个错误，导致可执行文件在根路径中搜索Qt库而不是安装位置。

示例错误：

dyld: Library not loaded: /usr/local/Qt-5.2.0/lib/QtGui.framework/Versions/5/QtGui
Referenced from: /Users/JRP/Dropbox/STANFORD/CS106B/HW1/build-Life-Desktop_Qt_5_2_0_clang_64bit-Debug/Life.app/Contents/MacOS/Life
Reason: image not found
The program has unexpectedly finished.

固定：

给定Qt安装路径，您应该运行：

sudo ln -s /Users/$USER/Qt5.2.0/5.2.0/clang_64/ /usr/local/Qt-5.2.0

要么

sudo ln -s /Users/ito/Qt/5.2.0/clang_64/ /usr/local/Qt-5.2.0

你想到了我的想法。它只是创建一个从qt安装位置到它正在寻找的位置的链接。

在Qt 5.11.3上，我重新启动了QtCreator，问题得到了解决！
