1) HOW TO COMPILE

Home page:
http://www.kalkulon.de

Latest source code:
Desktop: https://bitbucket.org/jholetzeck/kalkulon
Android: https://bitbucket.org/jholetzeck/kalkulon-for-android

There are three versions of Kalkulon
a) Console version (kkc) which should be compilable on every platform with 
   standard-conforming C++ compiler; source code files "core/*" 
b) GUI version (Kalkulon) which should be compilable on every platform providing
   at least Qt 4.2 framework (see http://qt-project.org); source code files
   "core/*" AND "gui/*"
c) Android port, the Kalkulon core is the same as for the desktop but GUI is written with
   Android framework in Java
   

Kalkulon can be built with freely available tools. The easiest way for Windows
and Linux is to get QtCreator from Qt website which contains Qt SDK, IDE and gcc compiler. 
For Windows I provide the binaries compiled with the open source version of 
Qt 4.x and the windows port of gcc MINGW.
For Android you need Android SDK and Android NDK installed.


a) I tested the console version with 
- VC++ 2010 Express (Windows)
- gcc/g++ on Linux (supporting readline library) and Windows
(no longer supported but may also work: VC6, VC2008 Express (/clr:pure))


If you want to compile as pure C++ code without any dependencies to external
libraries/APIs check the files stdafx.h and Makefile.* and undefine all
USE_xxx macros!

Windows:
change to directory "core"
- VC2010 C++ (Express): load kkc.sln and compile
- MINGW: check Makefile and run "mingw32-make"

Linux:
change to directory "core"
- be sure to either have readline developer files or undefine USE_READLINE in 
Makefile
- run "make"

To quick check the executeable run "kkc runregtest.k" (be sure that both files 
are in same directory and that subdirectory "examples" is also there)


b) I tested the GUI version with
- MINGW/Qt 4.8.x on Windows XP
- g++/Qt 4.7.x on Ubuntu 12.04

To compile (all platforms):
- be sure to have Qt 4.2.x (or higher) framework and suitable C++ compiler
  installed
- run "qmake"
- run "make"

To quick check the executeable run "Kalkulon" (be sure that "runregtest.k" and 
subdirectory "examples" is also there) and type in Kalkulon:
Load("runregtest.k")


c) Android for Kalkulon
- install Eclipse
- install Android SDK and NDK (Android 2.2 or higher)
- NDK is needed to compile Kalkulon core written in C++
- compile project with Eclipse

On the Android device the example and help files are automatically copied into
"<SDCARD>/Kalkulon" folder on first start. This is also the working directory
for Kalkulon. To quick check the executable type:
Load("runregtest.k")

The Exec() command works a little bit different on Android:
If the command is ACTION_EDIT or ACTION_VIEW, e.g.
Exec("ACTION_EDIT", "runregtest.k")
an Android Intent is sent to start an external Activity.
For all other commands a normal system() call is executed, e.g.
Exec("echo 1 > xxx") writes "1" into file "xxx" in Kalkulon folder.
