Description
Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.
Instructions for Windows
MinGW
- Download QT 4.5 Framework only for MinGW
- Run the exe and install QT 4.5. Depending on your MinGW version the installer may complain about a wrong w32api.h header file - proceed still.
- set environment variables (for MinGW and Visual C++) and add the bin directory to PATH
set QTDIR=C:\QT\4.5.0 set PATH=%SQTDIR%\bin;%PATH%
If you can run 'qmake' then everything is set up for CMake to find Qt.
Instructions for Linux
Using the system version of Qt
Make sure the binary version of the development package for libqt4 and all its dependencies have been installed for your distribution, and our CMake-based build system should do the rest. The libqt4 development package name varies from distribution to distribution, but on Debian it is called libqt4-dev, and on Fedora 10 it is called qt-devel-4.4.3-2.fc10.x86_64.rpm
Using a downloaded version of Qt
For convenience most Linux users will want to use the system version of Qt (see above), which for many distributions at this time of writing (2009-03) is version 4.4. However, we have noticed that Qt-4.5 has some bug fixes (e.g., better text placement results for SVG output) and new features (e.g., a viewBox capability for SVG output files). You can download a binary + source version of Qt-4.5 for either 32-bit Linux systems or 64-bit Linux systems. Once downloaded, change permissions on the installer to executable, and execute it to install the Qt4 software development kit at a location that you specify in answer to a question from the installer. Suppose, for example, that location prefix is /home/software/qtsdk-2009.01/. Then make the PLplot CMake-based build system aware of that location by putting qmake from that version on your path, for example, using
PATH='/home/software/qtsdk-2009.01/qt/bin:'$PATH
Then the PLplot CMake-based build system should do the rest.
Instructions for Mac OS X
- Download Qt for Open Source C++ development on Mac OS X (Carbon 32-bit). The Cocoa package should also work.
- Open the dmg-file and run the Qt.mpkg file which installs the Qt SDK.
- If you can run 'qmake' in a terminal then everything is set up for CMake to find Qt.
