Cantor

Cantor is a front-end for many mathematical software applications like Sage, Maxima, R and KAlgebra. Cantor belongs to The KDE Education Project and lets you use your favorite mathematical applications from within a nice KDE-integrated Worksheet Interface. It offers assistant dialogs for common tasks and allows you to share your worksheets with others.

Cantor's main features are:

Nice Worksheet view for evaluating expressions
View of plotting results inside the worksheet or in a separate window
Easy plugin based structure to add different Backends
GetHotNewStuff integration to upload/download example worksheets
Typesetting of mathematical formulas using LaTeX
Backend aware syntax highlighting
Plugin based assistant dialogs for common tasks (like integrating a function or entering a matrix)

Install Cantor

Cantor depends upon kdelibs, so in order to build Cantor, you must have kdelibs development files.

If you have a Linux box, then you can install the kdelibs-devel package from your distribution. If you have windows, then you can use The KDE on Windows Project, please note that there is already a Cantor.exe ported to windows, so is not necesary build the application. Otherwise, you can build and install kdelibs from sources.

The following steps can be used to build Cantor for a Linux distribution.

First obtain the sources

svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdeedu/cantor

Replace the the content of cantor/CMakeLists.txt with this

project(cantor)

    set( WITH_EPS Off )
  endif(LIBSPECTRE_FOUND)

add_subdirectory( src )
add_subdirectory( icons )
add_subdirectory( tests )

Type this 4 commands:

cd cantor
mkdir build
cd build
cmake ../

You can choose where to install with this param DCMAKE_INSTALL_PREFIX For example:

cmake -DCMAKE_INSTALL_PREFIX=/usr/ ../

1. Type this command

make install
