How to use CTelephony API with Qt Symbian

I want to use CTelephony API in Qt Symbian project but after including etel3rdparty.h and etel3rdparty.lib as library and header in .pro file like this:

LIBS += C:/NokiaQtSDK/Symbian/SDK/epoc32/release/armv5/lib/etel3rdparty.lib
INCLUDEPATH += C:/NokiaQtSDK/Symbian开发者_如何学Python/SDK/epoc32/include

I am getting a lot of compilation errors.

Please share if someone faced and find the solution of this problem.

You are not supposed to include each library with the complete path in the .pro file. You need only the name of the lib, without the extension, prefixed with -l, i.e. in your case

LIBS += -letel3rdparty

Also, you would normally not need to add epoc32\include to the include path, as it's added by default.
