QWT doesnt show any windows

[Cal]

hey,
i am new to qwt and have the problem, that if i run a qwt example it just terminates and doesnt show any windows.
im using eclipse, qt4.3, qwt5.2 and mingw under winXP.

that is what i tried:
i compiled qwt and got the libgwt5.a and the qwt.dll. The i created a new eclipse project and just copy/pasted the simple_plot example from the qwt examples folder.
i added the qwt source folder
"C:\Develop\qwt-5.2.0\src"
in the projects include paths and added
INCLUDEPATH += C:\Develop\qwt-5.2.0\src
LIBS += C:\Develop\qwt-5.2.0\lib\libqwt5.a
to my .pro file.

it doesnt give me any compile errors, but it doesnt show any widget-windows either.

i guess im doing sth wrong here, maybe someonce can tell me how to setup a windows eclipse for qwt properly?

thanks for your help!

Sounds like the traditional debug vs. release libraries mix up problem. Make sure to compile involved projects in the same mode.

hey jpn,
it doesnt work sadly.. neither in debug or release mode. and the debug mode doesnt give any usefull information either. i guess my .pro file isnt set up right. i dont really know how to link qwt properly.

Is noone using eclipse and qwt under windows? i would be really happy about a step-by-step installation guide cause the qwt lib would really save me a lot of work! or is there maybe a precompiled win-qwt-package?

[Cal]

ah crap! it works now.. i had to link to the libqwt.a instead of the libqwt5.a.

thank you!

Hi Cal,

I am having the same problem... but I couldn't find the libqwt.a I only have libqwt5.a... Also my examples are compiling fine but does show any executable file..


I would appreciate your help.

Cheers,

hey,

sadly i dont remember how i did it. i remember there is an file called INSTALL in the package and i compiled it using the instructions for "C) Win32/MinGW Qt4". i think that did it for me.

i hope that helps you...
