QT designer addtional plugin

hi,
I used QT 4 and
I have download QLed plugin and I would like to add it to QT designer for custum use.
I added the library file libqledplugin.so to /usr/lib/qt4/plugins/designer but I recieved the error The plugin uses incompatible QT library(4.5.3) release (same error on debug version)
Maybe some know how to fix it? :(

Thanks in advance,
Simabd

Build the plugin using the same version of Qt your Designer is built against (in release mode).

Please write me how could I upgrade QT designer to 4.5.3 as my QT creator. Or maybe how could I upgrade both to same version

Did you install Creator using your system's software package manager? Or did you download it separately in binary or source form?

hi wysota,
Many thanks for your help, I fixed now I could see QLed on QT designer.
I just modify the QT creator version to automatic version when I compile the QLed code and then copy this lib to designer lib and it's OK now.

Could you help me with wwWidget from my priviouse thread.

Thanks again amigo:D
