Third-party libraries

It uses the following libraries:

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)


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


CalcPi is built with CMake (, the multi-platform make tool. The Windows setups have been created with Unicode NSIS (

The GUI was designed with wxFormBuilder (
