Designer, plugins, Qt 4.8.3 and MinGW 4.6

**Sparhawk** · 7th November 2012, 20:00

Hi,

I'm not sure if Qt 4.8.3 is not compatible with MinGW 4.6.X or I'm doing something bad (last one, sure). I'm trying to compile Qt 4.8.3 on Windows 7 using MinGW 4.6.X (32 bits). I use:

configure -qt-style-windowsxp -qt-style-windowsvista -rtti -nomake demos -nomake samples.

Well, this is the .qmake.cache

Qt Code:

After that, all compile without any problems. But, my surprise is that I can't execute Qt Designer. If I remove all the .dll files on /plugins/designer, Qt Designer runs well. But if there are a dll-plugin, it crash (without any message). Dependency Walker show that Qt Designer has access to all DLL needed. Also the plugin DLL.

My application use own plugin (script, designer)... And crashes create the first QObject, on "new QObjectPrivate".

I think it is a problem on linkage and related with dll. Some clue?

Thanks a lot.
