C++ Question

install-name-tool does not add path to library when viewed through otool?

I finished my mac app using Xcode and Qt. Now I would like to prepare it for deployment to other macs. Inorder to do that I utilized macdeployqt.

I just created an app bundle with macdeployqt. However some of the libraries are missing. I attempted to follow [this][1] answer. Turns out I need to copy the missing dylib from my computer to the .app and then run install name tool. I have not gotten to the install-name tool yet as I am confused as to use

-id
or
-change
with it especially in my current scenario. Do I even need to use it ? Here is what I did so far.

Step 1: Running macdeployqt - this is a program that comes with Qt and embeds the necessary requirements of qt into the app.

> /Users/Guest/Qt/5.5/clang_64/bin/macdeployqt project2.app


Step 2: I then decided to run otool on the actual generated app binary

/Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS
> otool -L project2

Step 3:
However I noticed that my project2.app/Contents/Frameworks does not have those libraries inside them. So I decided to copy them manually.

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


Could you tell me what my next steps should be after copying those files ?

This is the output that I get when I attempt to run the app on another computer without using install_name_tool

Dyld Error Message:

Update:

After some struggling I decided to do the following

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 libosgGA.141.dylib @executable_path/../Frameworks/libosgGA.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libosgUtil.141.dylib @executable_path/../Frameworks/libosgUtil.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libosgViewer.141.dylib @executable_path/../Frameworks/libosgViewer.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


That did not seem to solve the problem as when I did this to one of the libraries that I just had added.

otool -L libosgDB.141.dylib
libosgDB.141.dylib:
@executable_path/../Frameworks/libosgDB.141.dylib (compatibility version 141.0.0, current version 3.5.1)

/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)


I am still not getting paths for the libraries
libOpenThreads.20.dylib , libosgUtil.141.dylib and libosg.141.dylib
any suggestions would be more than welcome.

Answer

libosg.141.dylib is a dylib that you're including in your built app.

You should actually look in your app's binary... that is:

otool -L /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2

As for resetting the path of the library to point to "@executable_path/../Frameworks/libosg.141.dylib" instead of the dylib in "/usr/local/lib", try doing this:

install_name_tool -change libosg.141.dylib @executable_path/../Frameworks/libosg.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
