Download + Install

Occay runs on Windows, Linux, and any other POSIX system (latter is untested).

You can download the source package and build it on your own. On Windows you may want to use the MinGW/MSYS development environment which works fine with the Makefile found in the source package. For all operation systems the FLTK GUI Toolkit Library (version 1.1.10) is required when building from source.
Alternatively, you may want to download the ready-to-run windows executable (recommended for Windows users). All necessary libraries are included.

The compiled software consists of a single file occay.exe which can be placed wherever you want to (so-called portable software).
If you want to "uninstall" Occay, just delete that occay.exe file.

About the project

Occay is written just for fun in the author's spare time and will updated from time to time.
It tries to pay homage to the ingenious HP Calculators, and not to serve as an emulation of any actual model.
