我使用 Xcode 和 Qt 完成了我的 mac 应用程序。现在我想准备将其部署到其他 Mac。为了做到这一点，我使用了 macdeployqt。
我刚刚使用 macdeployqt 创建了一个应用程序包。然而，一些图书馆不见了。我试图遵循 [this][1] 的答案。原来我需要将丢失的 dylib 从我的计算机复制到 .app，然后运行安装名称工具。我还没有使用 install-name 工具，因为我对使用-id或-change使用它感到困惑，尤其是在我目前的情况下。我什至需要使用它吗？这是我到目前为止所做的。
第 1 步：运行 macdeployqt - 这是 Qt 附带的程序，将 qt 的必要要求嵌入到应用程序中。
> /Users/Guest/Qt/5.5/clang_64/bin/macdeployqt project2.app
第 2 步：然后我决定在实际生成的应用程序二进制文件上运行 otool
> pwd
/Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS
> otool -L project2
project2:

第 3 步：但是我注意到我的 project2.app/Contents/Frameworks 里面没有这些库。所以我决定手动复制它们。
cp /usr/local/lib/libosg.141.dylib project2.app/Contents/Frameworks/libosg.141.dylib
cp /usr/local/lib/libosgDB.141.dylib project2.app/Contents/Frameworks/libosgDB.141.dylib
cp /usr/local/lib/libosgGA.141.dylib project2.app/Contents/Frameworks/libosgGA.141.dylib
cp /usr/local/lib/libosgUtil.141.dylib project2.app/Contents/Frameworks/libosgUtil.141.dylib
cp /usr/local/lib/libosgViewer.141.dylib project2.app/Contents/Frameworks/libosgViewer.141.dylib
cp /usr/local/lib/libosgManipulator.141.dylib project2.app/Contents/Frameworks/libosgManipulator.141.dylib
cp /usr/local/lib/libOpenThreads.20.dylib project2.app/Contents/Frameworks/libOpenThreads.20.dylib
你能告诉我复制这些文件后我的下一步应该是什么吗？
这是我尝试在另一台计算机上运行应用程序而不使用 install_name_tool 时得到的输出
Dyld Error Message:

更新：
经过一番挣扎后，我决定执行以下操作
install_name_tool -change libosg.141.dylib @executable_path/../Frameworks/libosg.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libosgDB.141.dylib @executable_path/../Frameworks/libosgDB.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2

install_name_tool -change libosgManipulator.141.dylib @executable_path/../Frameworks/libosgManipulator.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libOpenThreads.20.dylib @executable_path/../Frameworks/libOpenThreads.20.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
当我对我刚刚添加的一个库执行此操作时，这似乎并没有解决问题。
otool -L libosgDB.141.dylib

我仍然没有获得图书馆的路径，libOpenThreads.20.dylib , libosgUtil.141.dylib and libosg.141.dylib 任何建议都会受到欢迎。
