[mbasecalc Release 1.2]

Last Updated: Jan-07-2007

Table of Contents

mbasecalc is a clone of basecalc that comes with Xlib Programming Manual from O'Reilly as an example of X library programming. I work on Windows and Macs as well where X is not always available. So I wrote this one. I hope you'll find it useful too.

How it is written
A free cross platform toolkit (written in C++) called FLTK (Fast Light ToolKit) is used in order to make mbasecalc run in Linux/Unix, Mac OS X and Windows. You can get it from http://fltk.org/. I play with almost all freely available cross platform toolkits, I find fltk is the cleanest (and very fast) of all. And most of all, lots of fun to code with. I'm not a fan of GUI builders but FLTK has a gui builder called FLUID (Fast Light User Interface Design) which I actually can use. Please visit my fluid_hack page.

You need to download source if you you are on Linux/Unix (as well as the fltk). You can download and use the compiled binary for Mac OS X (on Intel) and Windows.

  • Download compiled binary for Windows:

In Linux/Unix, Mac OS X:

  • Download and install fltk first.
  • Download mbasecalc source.
  • At the shell prompt type:

$ gunzip < mbasecalc1.2.tar.gz | tar xvf -
$ cd mbasecalc1.2
$ sh ./configure
$ make clean
$ make

In Windows:
You can use the supplied binary mbasecalc.exe without compiling. But if you need to compile for some reason, download and compile the fltk library first. Download the gzip'd, tar'd mbasecalc source, extract the source, open a command shell and type:

cd mbasecalc
nmake -f Makefile.wnt

Note: you must have MS Visual C++ installed. It can be compiled without MS Visual C++ too, but you've to do it yourself (read fltk docs on that).

Keyboard Shortcuts
You can use mouse to do everything, but I like to use the keyboard shortcuts. Click right mouse button and select Keyboard Shortcuts for help. The keyboard shortcuts are shown below:

Keyboard Shortcuts Key in mbasecalc Description
Shift+h HEX Hexadecimal mode
Shift+d DEC Decimal mode (default)
Shift+o OCT Octal mode
Shift+b BIN Binary mode
Shift+u U Unsigned mode (default)
Shift+s S Signed mode
Ctrl+d CD Delete (same as Backspace)
Ctrl+e CE Erase All (from screen)
Ctrl+A CA Clear All
+-*/ +-*Add, substract and divide respectively
% % Modulus
|| Bitwise OR
&& Bitwise AND
^^ Bitwise XOR
~~ Bitwise NOT (One's complement)
>>> Right Shift
<<< Left Shift
=EnterCommit the operation

If you find the program useful, please let me know. Bug reports, suggestions are always welcome.

Thanks to Adrian Nye for writing basecalc in Xlib Programming Manual. I borrowed lots of code from basecalc.


  • Added configure script to Generate Makefile.
  • Compiled with fltk 1.1.7.
  • Colors on 2 buttons were not correct.
  • Compiled on my Intel MacBook running Mac OS X 10.4.8.

  • Thanks to Frank Jennings for providing binary for Mac OS X PowerPC.

  • version 1.1 released.
