Installing Qwt Using Qwt

Qwt (Qt Widgets for Technical Applications) is a 3rd party library of addon gui widgets for use with Qt. We use it mostly for display 2D graphs of simulation state in real time as a gui version of simulation is running.

This is the Qwt web web site.

Installing Qwt

Linux Install

For Ubuntu 12.04 (also works for Mint 12):

• sudo apt-get install libqwt-dev

For Ubuntu 10.04:

• sudo apt-get install libqwt5-qt4-dev
• Create the file /usr/share/qt4/mkspecs/features/qwt.prf with the following contents:
  • QwtVersion = 5.2.1
  • QwtBase = /usr
  • LIBS += -L$${QwtBase}/lib -lqwt-qt4
  • INCLUDEPATH += $${QwtBase}/include/qwt-qt4

For Fedora 16:

• sudo yum install qwt-devel
• Create the file /usr/share/qt4/mkspecs/features/qwt.prf with the following contents:
  • QwtVersion = 5.2.2
  • QwtBase = /usr
  • LIBS += -L$${QwtBase}/lib -lqwt
  • INCLUDEPATH += $${QwtBase}/include/qwt

Mac Install

Using macports:

• sudo port install qwt-dev
• sudo port activate qwt-devel @6.0.1_0

  Required because qwt (6.1.0-rc3) is too new for our code (we use depreciated functions).

If the above procedure doesn't work then try using the following (also using macports):

• sudo port install qwt-devel @6.0.1_0

Using either of the above macports based installs all libraries should be installed to /opt/local/lib and header files should be in /opt/local/include.

Windows Install

Windows 7

This assumes cygwin has already been installed.

• Open the cygwin terminal application (most likely on the desktop) and enter the following commands:
• svn co https://qwt.svn.sourceforge.net/svnroot/qwt/branches/qwt-6.0
• cd qwt-6.0
• cd qwt-6.0
• make && make install
• cp qwt.prf qwtconfig.pri /usr/share/qt4/mkspecs/features

Using Qwt

See the 2D lung model gui code for an example of how we use Qwt.
