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 at Ubuntu Karmic

For ubuntu karmic you just 3 commands in a terminal:

sudo add-apt-repository ppa:kubuntu-ppa/beta sudo apt-get update sudo apt-get install cantor

It will update all the KDE-packages to version 4.4, but this is useful for having no troubles with cantor.

Build and 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)

# search packages used by KDE
find_package(KDE4 4.3.80 REQUIRED)
if(WIN32)
  find_package(KDEWIN32 REQUIRED)
  # detect oxygen icon dir at configure time based on KDEDIRS - there may be different package installation locations
  execute_process(COMMAND "${KDE4_KDECONFIG_EXECUTABLE}" --path icon OUTPUT_VARIABLE _dir ERROR_QUIET OUTPUT_STRIP_TRAILING_WHITESPACE)
  file(TO_CMAKE_PATH "${_dir}" __dir)
  find_path(KDE4_ICON_DIR oxygen PATHS
      ${__dir}
  )
  message(STATUS "using oxygen application icons from ${KDE4_ICON_DIR}")
else(WIN32)
    set (KDE4_ICON_DIR  ${CMAKE_INSTALL_PREFIX}/share/icons)
endif(WIN32)

include(KDE4Defaults)
include(MacroLibrary)

if(NOT WIN32)
  macro_optional_find_package(LibSpectre)
  macro_log_feature(LIBSPECTRE_FOUND "libspectre" "A PostScript rendering library" "http://libspectre.freedesktop.org/wiki/" FALSE "${LIBSPECTRE_MINIMUM_VERSION}" "Support for rendering EPS files in Cantor.")

  if(LIBSPECTRE_FOUND)
    set( WITH_EPS On )
  else(LIBSPECTRE_FOUND)
    set( WITH_EPS Off )
  endif(LIBSPECTRE_FOUND)
else(NOT WIN32)
  set( WITH_EPS Off )
endif(NOT WIN32)

include_directories( ${KDE4_INCLUDES} ${QT_INCLUDES} )

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/ ../

Type this command

make install
