I use QGIS 2.12 in my standalone application. Now I want to upgrade my application to the lastest QGIS version (2.16). I use OSGeo4W installer to download all headers, libs and other files. I have three directories with QGIS after installation:
In every directory I can find
qgis_gui.dll. But all of them depends from release Qt libraries so I can't debug my application in Visual Studio?
It crashes with error
"Must construct QApplication before QPaintDevice".
When I use QGIS 2.12 I had debug and release versions of this libraries.
My question is where I can find debug versions to run my application in debug mode?
