无法在mac上安装qwt designer插件

问题描述：

我无法在我的Mac上安装qwt designer插件。 我已经下载了v 6.1.3，并且成功完成了qmake，make和sudo make install。无法在mac上安装qwt designer插件

问题是，在/usr/local/qwt-6.1.3/lib下我只有文件qwt.framework，而不是类似libqwt.5.dylib，如安装指南所述。由于这个原因，我不能按照指导......

答

首先Qwt 6现在使用一个框架。这意味着不再有qwt.dylib文件。如果你要链接到它，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安装文件夹。

原则上你可以简单地设置一个环境变量，例如

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

但是，无论出于何种原因，这并不适用于我。

伤了一些头发，但这里是我如何通过自制软件工作。

1）brew install qt5 qwt

2）brew cask install qt-creator

3）插件dylib复制到您的Qt Creator的插件文件夹：

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（递归）复制到应用程序的框架文件夹：

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

5）尝试运行Qt Creator并在尝试打开表单设计器时发现它崩溃。嘘。

6）运行的插件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/local/Cellar/qwt/6.1.3_1/lib/qwt.framework/Versions/6/qwt (compatibility version 6.1.0, current version 6.1.3)

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

在这一点上，你可以比较实际工作的插件，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，所以我们需要链接到Qt的本地版本。你需要小心寻找每一个Qt框架的参考。在这种情况下，有两个地方：

1）在插件dylib

2）在框架库

这是我跑：

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，有对QtOpenGL的引用。然而，这个框架没有包含在我的Qt Creator版本中，所以我把它指向了/usr/local/opt/ ...。似乎没有什么区别。

最后我otool结果是：

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)

然后当你打开Qt Creator中你应该看到这一点：
