    Default [Qwt] Make problem with Qwt on QtCreator-Windows 7

    Hi !!

    I use QtCreator on Windows7. and everything just works fine !!
    I installed Qwt this morning, following exaclty the steps given in this post: http://www.qtcentre.org/threads/2617...or-on-Windows:

    This is how I setup:
    1. I unzip everything to C:\Qt\2009.04\qwt-5.2.0 folder (C:\Qt\2009.04 is my QT Creator install folder).
    2. I open C:\Qt\2009.04\qwt-5.2.0\qwtconfig.pri file with text editor
    3. enabled debug and release build (around line 50 to line 53)
    4. build static libraries instead of shared (around line 77 to line 79)
    5. save and close the file.
    6. open the C:\Qt\2009.04\qwt-5.2.0\qwt.pro file w/ QT and rebuild the whole thing
    7. open my own project file (<project_name>.pro)
    8. add the following lines to the end of the pro file:

    Qt Code: 
    1. Switch view 1.QWT_LOCATION = C:/Qt/2009.04/qwt-5.2.0 # Qwt location (must match exactly to where you unzip the files)2.INCLUDEPATH += $${QWT_LOCATION}/src3.LIBS = -L$${QWT_LOCATION}/lib \4.    -lqwt5. 6.# The following section is to select static lib base on debug or release build7.if(!debug_and_release|build_pass):CONFIG(debug, debug|release) { 8.    mac:LIBS = $$member(LIBS, 0) \9.        $$member(LIBS, 1)_debug10.    win32:LIBS = $$member(LIBS, 0) \11.        $$member(LIBS, 1)d12.}QWT_LOCATION = C:/Qt/2009.04/qwt-5.2.0 # Qwt location (must match exactly to where you unzip the files)
    2. INCLUDEPATH += $${QWT_LOCATION}/src
    3. LIBS = -L$${QWT_LOCATION}/lib \
    4.     -lqwt
    5.  
    6. # The following section is to select static lib base on debug or release build
    7. if(!debug_and_release|build_pass):CONFIG(debug, debug|release) { 
    8.     mac:LIBS = $$member(LIBS, 0) \
    9.         $$member(LIBS, 1)_debug
    10.     win32:LIBS = $$member(LIBS, 0) \
    11.         $$member(LIBS, 1)d
    12. }
    To copy to clipboard, switch view to plain text mode 
    9. to link to the qwt, use #include <lib_file>. (for example, u need #include <qwt_plot.h> for your code to be able to allocate QwtPlot object.
    10. build your application.

    The Qwt examples execute without any problems.
    But when I try to run a project of my own, I get these error messages related to the Make step:

    Qt Code: 
    1. Exécution des étapes de compilation pour le projet plotscroll...
    2. Configuration non modifiée, passe l'étape QMake.

    28. 	win.cpp \
    29.         main.cpp

    How can I fix this ?
    Thank you for your help !!

    Ok..I found my error :

    I enabled the release configuration instead of only the debug and build all in the qwt.pri:

    Qt Code: 
    1. #CONFIG          += release     # release/debug/debug_and_release
    2.         CONFIG           += debug_and_release
    3.         CONFIG           += build_all

    I'm also on Win7 and I'm stuck. Can't get the qwt-widgets to show in the Qt designer.
    I'm trying to do exactly as you are so just to be sure:
    "6. open the C:\Qt\2009.04\qwt-5.2.0\qwt.pro file w/ QT and rebuild the whole thing"
    Do you actually open the .pro-file and rebuild it from Qt Creator? Using (Build->rebuild project "qwt") from the menu?

    That is what I do and I don't get any errors but I also don't get any new widgets in my Qt Designer. (Of course I first tried the way(s) that the manual suggested but no luck there either.)

    What versions of Qt, Qt creator and qwt are you using?

    Help will be very much appreciated!

    Thanks!
