Problem with GCC-Plugin combination

[Ratzz]

I just tested Custom widget Plugin example in the release mode which generated the .SO file for me .
I think there is a problem with my gcc
About QtCreator says

Qt Creator 3.4.2 (opensource)
Based on Qt 5.5.0 (GCC 4.9.2 20150212 (Red Hat 4.9.2-6), 32 bit)

But installed gcc is -> gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4
Will that work??
I copied the .so file to the /opt/Qt5.5.0/Tools/QtCreator/lib/qtcreator/plugins/( path which is the libWelcome.so) still i could not see plugin in the QtCreator.

Hi,

Which version of Qt are you using to build the plugin ?

@SGaist
Thanks for the reply .
I am using 5.5.0

Silly question but are you building the plugin in 32bit ?

[Ratzz]

@SGaist
Yes , 32 Bit

Then you should start Qt Creator from the command line with QT_DEBUG_PLUGINS=1 set to see what is happening. Beware of the size of the output, Qt Creator is a plugin based application.
