Need help installing Qwt

[mpita]

If you want to use the qwt designer plugin the esiest way is to copy the 'qwt_designer_plugin.dll' file inside 'plugins\designer' of your qt framework. It's not the right way but, it works in 2 seconds (and worked for me). Then via 'About Plugins' inside the Designer's Help menu you should see if the plugin is successfully been loaded.

If examples are already compiled, their binaries lay on C:\<path of your qwt sources>\examples\bin.

If your creator doesn't find any qwt header, try to set in yout project file

INCLUDEPATH += <qwt installation path>/include/

Then run qmake again. Try to add #include <qwt_curve_plot.h>

Ciao!

2 seconds of wasted time, because he already configured the path ( what also works in 2 seconds ) + a source for having problems in the future.

Instead the missing step should be to configure the environment ( PATH, LD_LIBRARY_PATH ... ), so that the Creator can find the Qwt library, when it is loading the plugin.

Of course Qwt plugin/library need to be compatible with the Creator - that doesn't need be compatible to the Qt version you are trying to build your application with.
So when Creator and Qt installation are incompatibel you need to build and install Qwt twice.
