I'm trying to deploy a Qt application on OS X using macdeployqt:

macdeployqt MyApplication.app -dmg

The application uses the Qwt library, which is being included in the PRO file as follows:

macx: QWT_ROOT = /usr/local/qwt-6.1.0 include ( $${QWT_ROOT}/features/qwt.prf )

When I run the macdeployqt command I get the following error message:

ERROR: no file at "/Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/qwt"

I'm not sure but it seems the deployment step is looking for the Qwt library on the wrong path, for example:

"/Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/qwt"

When it should be:

"/Library/Frameworks/qwt.framework/Versions/6/qwt"

How can I solve it?

  • As a workaround it is possible to create the directory `sudo mkdir -p /Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/` and make a symply bridge as virtual link `ln -s /usr/local/qwt-6.1.3/lib/qwt.framework/Versions/Current/qwt /Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/qwt` as explained [here](https://forum.qt.io/topic/83121/error-deploying-qt-application-on-os-x/13). Note: I'm not sure if it solves the problem because I had other issues, but that error message disappeared. – KelvinS Sep 11 '17 at 13:03

I have uninstalled other qt versions using brew list, brew remove qt and brew remove qt5. I also noted that I had pyqt installed (and I was not using it), so I also remove it using brew remove pyqt.

Then, I have reinstalled Qt 5.3.2 and had other issues:

Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild.

Which was solved changing the isEmpty($$list($$system("/usr/bin/xcrun -find xcrun 2>/dev/null"))) command from the Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf file to isEmpty($$list($$system("/usr/bin/xcrun -find xcodebuild 2>/dev/null"))), as explained here: Qt Creator - Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild

and

Could not resolve SDK path for 'macosx10.8'

That was solved by changing the QtPath/5.3/clang_64/mkspecs/qdevice.pri from !host_build:QMAKE_MAC_SDK = macosx10.8 to !host_build:QMAKE_MAC_SDK = macosx10.12, as explained here: Error: Could not resolve SDK path for 'macosx10.8'

So, I run the command from my Qt directory:

/Users/kuser/Qt5.3.2/5.3/clang_64/bin/macdeployqt MyApplication.app -dmg

and it worked.

I found these solutions in comments from the following question:

Qt5 cannot find platform plugins Mac OS X

Note: this does not solve the macdeployqt error directly, but as it is part of the Qt installation, reinstalling it solved my problem.
