Hi,
I'm a newbie about Windows but started to try to compile my QtC
plugin under a Windows7 VM, I did the following steps:
1. Installed Qt + QtCreator (checked some MSVC runtime libraries
too).
2. Cloned QtC and checked it to version 3.6.1.
3. Cloned my plugin[1] and checked it to branch qtc-3.6.
4. Did open the plugin project (.pro) into QtCreator.
5. Added QTC_SOURCE and QTC_BUILD variables to the qmake call.
Triggered the compilation and everything went fine until... link
time, on Windows my plugin is looking for some dependencies unknow
to me, here the linker output.

To me it looks like you tried to build your plugin in Release
against a Qt Creator in Debug, so it tries to find e.g.
Aggregation.dll where there is only Aggregationd.dll etc (note the
additional ‘d’ at the end).
Hm, actually it looks like you built against the release build of
Qt Creator that comes with the Qt package
C:\Qt\Tools\QtCreator\lib\qtcreator\plugins
The Qt Creator packages are built with MSVC2013. You cannot link a
MinGW compiled plugin against that.
And I should add:
On Windows the Qt Creator packages do not contain all the necessary
files (*.lib) to develop against it anyhow.
You need to do your own build of Qt Creator and link against that,
even when using MSVC2013.
This was exactly what happened, I compiled it against the QtC
installed, not a custom build, so just a final question:
Will the plugin compiled with MinGW, linked against a QtC built with
MinGW, load on the original QtC binary distribution?
I'm asking this because my final target is just to create a small
installer for the plugin that works with some original QtC binary
windows distribution.
Thanks everyone for the help.
