pMath

Copyright © Peter Frentrup, 2005-2024

pMath is an experimental computer algebra system/programming language. Some concepts are similar to Mathematica (usage of pattern matching, everything is an expression, automatic data-binding with Dynamic), but with improved syntax. Development takes place on BitBucket.

Build

The Code::Blocks IDE is used for development. Supported compilers are Microsoft Visual C++ (Windows, recommended) and GCC (Windows, Unix).

Prerequisites

When opening pmath.workspace for the first time, Code::Blocks will ask for many Global Variables. These correspond to required prebuild libraries. The variable names are of the form name_32 or name_64 for 32 and 64 bit flavors, respectively. You may choose to either only set the 32 bit versions or only the 64 bit versions or both. The relevant variables for the core pMath library are:

• gmp_32/gmp_64 points to the MPIR (Multiple Precision Integers and Rationals) installation directory.

  Set include to the include directory (containing gmp.h).
  Set lib to the library directory (containing mpir.lib or libmpir.a).
  Set bin to the binary directory (containing mpir.dll).

• mpfr_32/mpfr_64 points to the MPFR (Multiple Precision Floating-point with correct Rounding) installation directory.

  Set include to the include directory (containing mpfr.h).
  Set lib to the library directory (containing mpfr.lib or libmpfr.a).
  Set bin to the binary directory (containing mpfr.dll).

• flint_32/flint_64 points to the FLINT (Fast Library for Number Theory) installation directory.

  Set include to the include directory (containing flint.h).
  Set lib to the library directory (containing dll_flint.lib or libflint.a).
  Set bin to the binary directory (containing dll_flint.dll).

• arb_32/arb_64 points to the Arb (Arbitrary-precision interval arithmetic using Real Balls) installation directory.

  Set include to the include directory (containing arb.h).
  Set lib to the library directory (containing arb.lib or libarb.a).
  Set bin to the binary directory (containing arb.dll).

• iconv_32/iconv_64 points to an iconv installation directory for character set conversion. On Windows, win_iconv is a good choice.

  Set include to the include directory (containing iconv.h).
  Set lib to the library directory (containing iconv.lib or libiconv.a).
  Set bin to the binary directory (containing iconv.dll). For Unix systems you can typically leave bin and lib empty because iconv is implemented by the standard library.

• pcre_32/pcre_64 points to the PCRE (Perl Compatible Regular Expressions) installation directory.

  Set include to the include directory (containing pcre.h).
  Set lib to the library directory (containing pcre16.lib or libpcre16.a).
  Set bin to the binary directory (containing pcre16.dll).

• zlib_32/zlib_64 points to the zlib installation directory for compression.

  Set include to the include directory (containing zlib.h).
  Set lib to the library directory (containing zlib.lib or libzlib.a).
  Set bin to the binary directory (containing zlib.dll).

The graphical front-end richmath uses the Cairo graphics library together with the Win32 API on Windows and Gtk on Linux.

Building the required libraries from source on Windows

It is recommended to use Visual C++ 2015 (MSVC for short) to build the libraries. For MPIR and MPFR there are MSVC projects available at http://www.github.com/BrianGladman/mpir and http://www.github.com/BrianGladman/mpfr, respectively.
