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

    Hi!

    (Original question in SO: http://stackoverflow.com/questions/3...lar-in-windows)

    I'm trying to install QwtPolar 1.1.1 in Windows over Qwt 6.1.2.

    I managed so far to successfully install Qwt and I can see the .prf and 2 .pri in the features folder. Then I go to the QwtPolar folder, call for qmake -set QMAKEFEATURES C:\Qt\Qwt-6.1.2 and check if it was added with qmake -query, which returns positive. Then I call qmake qwtpolar.pro with no problems, but when mingw32-make is called, I always get the same error: it wasn't possible to find some Qwt headers.

    Judging Uwe's final answer in this thread, I suppose qmake is failing to do it's job with the .prf since I can't see, in the error message, the moment where the qwt header files are supposed to be included:

    Well I ran out of options. What should I do?
    May the Lord be with you. Always.

    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.
