無法在mac上安裝qwt designer插件

Question

我無法在我的Mac上安裝qwt designer插件。 我已經下載了v 6.1.3，並且成功完成了qmake，make和sudo make install。

問題是，在/usr/local/qwt-6.1.3/lib下我只有文件qwt.framework，而不是類似libqwt.5.dylib，如安裝指南所述。由於這個原因，我不能按照指導......

Answer 1

首先Qwt 6現在使用一個框架。這意味着不再有qwt.dylib文件。如果你要鏈接到它，你只需添加到您的.pro文件：

include (/usr/local/opt/qwt/features/qwt.prf) 
CONFIG += qwt 

或任何你QWT安裝文件夾。

原則上你可以簡單地設置一個環境變量，例如

QT_PLUGIN_PATH="/usr/local/opt/qwt/lib/qt5/plugins:$QT_PLUGIN_PATH" 
export QT_PLUGIN_PATH 

但是，無論出於何種原因，這並不適用於我。

傷了一些頭髮，但這裏是我如何通過自制軟件工作。

1）brew install qt5 qwt

2）brew cask install qt-creator

3）插件dylib複製到您的Qt Creator的插件文件夾：

sudo cp /usr/local/opt/qwt/lib/qt5/plugins/designer/libqwt_designer_plugin.dylib /Applications/Qt Creator.app/Contents/PlugIns/designerlibqwt_designer_plugin.dylib 

4）的框架（遞歸）複製到應用程序的框架文件夾：

sudo cp -R /usr/local/Cellar/qwt/6.1.3_1/lib/qwt.framework /Applications/Qt\ Creator.app/Contents/Frameworks/ 

5）嘗試運行Qt Creator並在嘗試打開表單設計器時發現它崩潰。噓。

6）運行的插件dylib otool -L：

> otool -L libqwt_designer_plugin.dylib 

/usr/local/opt/qwt/lib/qt5/plugins/designer/libqwt_designer_plugin.dylib (compatibility version 0.0.0, current version 0.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0) 

在這一點上，你可以比較實際工作的插件，qtquick：

libqquickwidget.dylib (compatibility version 0.0.0, current version 0.0.0) 
@rpath/QtDesigner.framework/Versions/5/QtDesigner (compatibility version 5.7.0, current version 5.7.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1) 

好了，所以我們需要鏈接到Qt的本地版本。你需要小心尋找每一個Qt框架的參考。在這種情況下，有兩個地方：

1）在插件dylib

2）在框架庫

這是我跑：

sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtGui.framework/Versions/5/QtGui" "@rpath/Frameworks/QtGui.framework/Versions/5/QtGui" libqwt_designer_plugin.dylib 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtCore.framework/Versions/5/QtCore" "@rpath/Frameworks/QtCore.framework/Versions/5/QtCore" libqwt_designer_plugin.dylib 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtWidgets.framework/Versions/5/QtWidgets" "@rpath/Frameworks/QtWidgets.framework/Versions/5/QtWidgets" libqwt_designer_plugin.dylib 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtDesigner.framework/Versions/5/QtDesigner" "@rpath/Frameworks/QtDesigner.framework/Versions/5/QtDesigner" libqwt_designer_plugin.dylib 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtXml.framework/Versions/5/QtXml" "@rpath/Frameworks/QtXml.framework/Versions/5/QtXml" libqwt_designer_plugin.dylib 
sudo install_name_tool -change "/usr/local/Cellar/qwt/6.1.3_1/lib/qwt.framework/Versions/6/qwt" "@rpath/Frameworks/qwt.framework/Versions/6/qwt" libqwt_designer_plugin.dylib 


sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtPrintSupport.framework/Versions/5/QtPrintSupport" "@rpath/Frameworks/QtPrintSupport.framework/Versions/5/QtPrintSupport" qwt 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtWidgets.framework/Versions/5/QtWidgets" "@rpath/Frameworks/QtWidgets.framework/Versions/5/QtWidgets" qwt 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtCore.framework/Versions/5/QtCore" "@rpath/Frameworks/QtCore.framework/Versions/5/QtCore" qwt 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtGui.framework/Versions/5/QtGui" "@rpath/Frameworks/QtGui.framework/Versions/5/QtGui" qwt 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtSvg.framework/Versions/5/QtSvg" "@rpath/Frameworks/QtSvg.framework/Versions/5/QtSvg" qwt 
sudo install_name_tool -change "/usr/local/opt/qt5/lib/QtConcurrent.framework/Versions/5/QtConcurrent" "@rpath/Frameworks/QtConcurrent.framework/Versions/5/QtConcurrent" qwt 

注意，在QWT，有對QtOpenGL的引用。然而，這個框架沒有包含在我的Qt Creator版本中，所以我把它指向了/usr/local/opt/ ...。似乎沒有什麼區別。

最後我otool結果是：

otool -L qwt 
qwt: 
    /usr/local/opt/qwt/lib/qwt.framework/Versions/6/qwt (compatibility version 6.1.0, current version 6.1.3) 
    @rpath/Frameworks/QtPrintSupport.framework/Versions/5/QtPrintSupport (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtWidgets.framework/Versions/5/QtWidgets (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtGui.framework/Versions/5/QtGui (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtCore.framework/Versions/5/QtCore (compatibility version 5.7.0, current version 5.7.0) 
    /System/Library/Frameworks/DiskArbitration.framework/Versions/A/DiskArbitration (compatibility version 1.0.0, current version 1.0.0) 
    /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0) 
    @rpath/Frameworks/QtSvg.framework/Versions/5/QtSvg (compatibility version 5.7.0, current version 5.7.0) 
    /usr/local/opt/qt5/lib/QtOpenGL.framework/Versions/5/QtOpenGL (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtConcurrent.framework/Versions/5/QtConcurrent (compatibility version 5.7.0, current version 5.7.0) 
    /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0) 
    /System/Library/Frameworks/AGL.framework/Versions/A/AGL (compatibility version 1.0.0, current version 1.0.0) 
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.4.0) 
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0) 

和：

otool -L libqwt_designer_plugin.dylib 
libqwt_designer_plugin.dylib: 
    /usr/local/opt/qwt/lib/qt5/plugins/designer/libqwt_designer_plugin.dylib (compatibility version 0.0.0, current version 0.0.0) 
    @rpath/Frameworks/qwt.framework/Versions/6/qwt (compatibility version 6.1.0, current version 6.1.3) 
    @rpath/Frameworks/QtDesigner.framework/Versions/5/QtDesigner (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtWidgets.framework/Versions/5/QtWidgets (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtGui.framework/Versions/5/QtGui (compatibility version 5.7.0, current version 5.7.0) 
    @rpath/Frameworks/QtCore.framework/Versions/5/QtCore (compatibility version 5.7.0, current version 5.7.0) 
    /System/Library/Frameworks/DiskArbitration.framework/Versions/A/DiskArbitration (compatibility version 1.0.0, current version 1.0.0) 
    /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0) 
    @rpath/Frameworks/QtXml.framework/Versions/5/QtXml (compatibility version 5.7.0, current version 5.7.0) 
    /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0) 
    /System/Library/Frameworks/AGL.framework/Versions/A/AGL (compatibility version 1.0.0, current version 1.0.0) 
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.4.0) 
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0) 

然後當你打開Qt Creator中你應該看到這一點：
