Third-party libraries

It uses the following libraries:

• wxWidgets, the multiplatform GUI library (http://www.wxwidgets.org/)
• boost (http://www.boost.org/)
• GMP or MPIR (http://gmplib.org/ or http://www.mpir.org/) for arbitrary precision calculation
• MPFR (http://www.mpfr.org/) for arbitrary precision floats
• Eigen (http://eigen.tuxfamily.org/index.php?title=Main_Page) for linear algebra (estimating the time and memory consumption)

Since all of these libraries are multi-platform, the source code should compile on almost any desktop OS. I have tested the following platforms:

• Windows, from XP to 8, 32 and 64 bits. It is possible to use either Visual C++ compiler or MinGW32/MinGW64
• Linux (I tested with Ubuntu x64 and Raspbian, a Debian version for Raspberry Pi)
• OS X (I'm not a OS X expert, and I don't own a Mac myself, therefore I don't provide OS X binaries)

Algorithms

CalcPi contains several algorithms for calculating Pi and e (base of natural logarithm). These algorithms were implemented by others:

• GMP-Chudnovsky (http://gmplib.org/pi-with-gmp.html)
• Parallel GMP-Chudnovsky (http://gmplib.org/list-archives/gmp-discuss/2008-November/003444.html)
• MPFR (http://www.mpfr.org/)

Build-system

CalcPi is built with CMake (http://www.cmake.org/), the multi-platform make tool. The Windows setups have been created with Unicode NSIS (http://www.scratchpaper.com/).

The GUI was designed with wxFormBuilder (http://wxformbuilder.org/).
