    Hi
    I installed Qwt 6.1.2 with Qt 5.2.0.

    To get rid of the urge to search for the Qt dlls under cygwin, I added PATH to look at bin under Qt. I also changed the qwtconfig.pri with the following addition under win32:

    LIBS += -LC:/Qt/Qt5.2.0/5.2.0/mingw48_32/lib

    Compiled without an issue.

    But, Now, when I open any example (I tried CPUPLOT and EXAMPLES) and run it I get:
    Starting C:\qwt-6.1.2\examples\bin_debug\cpuplot.exe...

    in the Application output, but No corresponding GUI Is displayed!!!

    I have no idea what is happening.

    Thanks for any insight.

    This is a WIn XP machine and code I wrote without Qwt displays GUI without issues.

      All may not be OK with my compile, I just realised there is no exe created in my debug folder.

      Where should it be?

      QCustomPlot works fine.

        Hi,

        Do you have any error message ?

        It should be created exactly where you see it after "Starting C:\etc."

          no error messages at all! I had this happen once on a different machine - having 2 versions of mingw with code blocks ended up deleting the .exe whenever I ran any application developed via code blocks. Reinstalling everything and then running applications fixed it.

            No energy to redo all that in this old xp :( I do have 2 versions of mingw on this machine, one installed via Qt, old one from code blocks.

            Sorry for the double post, 5 year old running circles around me literally. Other code - ones I wrote, QCustomplot all continue to work normally.
