Hi,

I am trying to link an application using QGIS API. Everything works on Linux but in Windows (QT 4.8.1 + Visual Studio Express 2010) I get:

Qt Code: 
  1. 1>maptoolselect.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsVectorLayer::staticMetaObject" (?staticMetaObject@QgsVectorLayer@@2UQMetaObject@@B)
  2. 1>mapwidget.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsVectorLayer::staticMetaObject" (?staticMetaObject@QgsVectorLayer@@2UQMetaObject@@B)
  3. 1>mapwidget.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsRasterLayer::staticMetaObject" (?staticMetaObject@QgsRasterLayer@@2UQMetaObject@@B)
  4. 1>debug\\nile.exe : fatal error LNK1120: 2 unresolved externals
To copy to clipboard, switch view to plain text mode 

my pro file is defined as:

Qt Code: 
  1. QT       += core gui sql xml
  2.  
  3. TARGET = nile
  4. TEMPLATE = app
  5.

I tried to generate a Visual Studio project with
Qt Code: 
  1. qmake -tp vc
To copy to clipboard, switch view to plain text mode 

but I get the same error.

Any help is much appreciated!.
