Qt creator windows sdk install#
I found the right combination of the above mentioned items to make it possible for Qt to import Qgis libraries and build the app: I'm actually porting a PyQgis app I've made two years ago and as I'm fairly new to Qt Creator I'm stuck at he beginning. Then it fails to build/compile whith this error: main.cpp:20: error: undefined reference to `QgsApplication::QgsApplication(int&, char**, bool, QString const&, QString const&)' QgsApplication::setPrefixPath("C:/OSGeo4W64/apps/qgis-dev", true) #DEFINES += GUI_EXPORT=_declspec(dllimport) CORE_EXPORT=_declspec(dllimport) LIBS += -L"C:/OSGeo4W64/apps/qgis-rel-dev/lib" -lqgis_core -lqgis_gui INCLUDEPATH += "C:/OSGeo4W64/apps/qgis-rel-dev/include" GreaterThan(QT_MAJOR_VERSION, 4): QT += widgets The following is just a test I can't get working. Qt works Ok in every case with it's own libraries, but when I try to import QGIS libraries it gives an 'undefined reference' error when building, even though intellisense works fine as it recognizes QgsApplication as a member of qgsapplication.h.
Qt creator windows sdk windows 10#
Windows version: I'm using Windows 10 64bit. I've tried to compile QGIS from source using MinGW with no success (again, versions compatibility issues). QGIS compile: I only use the regular OSGeo4w installer and AFAIK QGIS is compiled with Qt4 and MSVC. Qt compiler: tried MinGW, VS2008 Express (Qt 4.8.6) and VS Community 2017 (Qt 5.9).
What I need is an overall guideline about the compatibility of the following items that help me find the right combination: The information is mostly outdated and I havent't found a solution. I've read several topicts at gis.stackexchange and from other sources. I'm trying to develop a QT C++ application that uses QGIS API and I can't manage Qt Creator to compile the code.
