Error finding qwt include files when trying to install qwtpolar in Windows

[Uwe]

Check your files in "C:\Qt\Qwt-6.1.2\features". If everything looks o.k. you could try to modify "qwtpolarbuild.pri" and replace "CONFIG += qwt" by "include ( C:\Qt\Qwt-6.1.2\features/qwt.prf )".

If this works you know, that you have a problem with setting QMAKEFEATURES. If not you probably have an invalid Qwt installation and you need to reinstall Qwt like being described in the Install advices.

Hi, Uwe!

Thanks for the help; the change worked.

If you want, you may put the same answer in SO and I'll accept it.

Well it is more a workaround, than a solution, but it showed, that your installation is fine and your problem is simply a bad setting of QMAKEFEATURES. Setting the path in a correct syntax should also not be that hard.
