QT EWO

[kkembel]

Hello All,

Trying to build the basic EWO template and keep getting undefined reference errors (11 total... the following is just one of those):

C:\\Siemens\\Automation\\WinCC_OA\\3.13\\api\\mine\\mine.cxx error: undefined reference to `_imp___ZN16BaseExternWidget6signalERK7QStringRK8QVariant'

Using MinGW QT editor on Windows 7 Pro... QT version is 5.3.2 OA is v3.13p8 ..the BaseExternWidget class is not recognized

I have set the following environment system variables:

variable name:
API_ROOT

variable value:
C:\\Siemens\\Automation\\WinCC_OA\\3.13\\api

AND

variable name:
PLATFORM

variable value:
%API_ROOT%\\platform

Appreciate your time:
Kurk

MinGW compiler is not supported (I'm not sure but it probably uses a different ABI than the Visual Studio compiler).
