I click the Icon, and it will flash but will not open. Qt Creator works, but I'm trying to use Python. I've tried remove and install a couple times, but still nothing. I have downloaded PyQt4, Ubuntu-SDK, Qt4 (Designer, Linguist and Assistant). I appreciate your help.

Tried designer-qt4 , Result:

designer-qt4: symbol lookup error: /usr/lib/x86_64-linux-gnu/qt4/plugins/designer/libqcscintillaplugin.so: undefined symbol: _ZN13QsciScintillaC1EP7QWidget

Try installing qt4-default:

sudo apt-get install qt4-default
user.dz

  • Didn't seem to help, Qt4 Designer still wont load – berrywhitex Jul 13 '14 at 06:19
  • @berrywhitex, I could not find any package that provides libqcscintillaplugin.so. Have you installed some thing related from a PPA? Could add output of dpkg -S /usr/lib/x86_64-linux-gnu/qt4/plugins/designer/libqcscintillaplugin.so – user.dz Jul 13 '14 at 06:46

I went to the location of the file libqcscintillaplugin.so, and removed the file.

Or through cleaner way, better to use APT:

sudo apt-get remove libqscintilla2-designer

Now Qt4 Designer opens without a problem.

  • You can accept your own answer, but do you know from where did you get this file. Have you installed scintilla editor or plugin before. – user.dz Jul 14 '14 at 23:42

    I'm pretty sure I got the file in an add-on that came with Qt4 Designer from the software center. The add-on is Qt4 Designer Plugin for QScintilla2 `libqscintilla2-designer'. P.S. I had to wait to accept my answer due to reputation. – berrywhitex Jul 15 '14 at 16:54
