The following is a missing piece of documentation for adding new .pyx to the Sage library: See [http://www.sagemath.org/doc/html/prog/node40.html 5.2] of the [http://www.sagemath.org/doc/html/prog/prog.html Sage Programming Guide].


Writing Optimized Compiled Code with Sage


Creating .pyx Files in the Sage Library

Suppose you want a more permanent way of including your optimized Cython code in Sage. Perhaps you want to contribute to the Sage project? This guide will show you how to create a simple Cython module and then link it to the Sage library so that your code will appear in future versions of Sage.


Opentick provides free real-time and historical market data for trading systems and trading platforms. See www.opentick.com.

This package is used by the sage.finance module.

  • Bootstrap the autotool build system:
    •    $ autoreconf -i 
           configure.ac:8: installing `./missing' 
           configure.ac:8: installing `./install-sh' 
           Applications/HistCsv/Sources/Makefile.am: installing `./depcomp'
  • Configure, make, and install Opentick source in src/ to $SAGE_ROOT. Libraries are put into $SAGE_LOCAL/lib and headers into $SAGE_LOCAL/include:

    •    ./configure --prefix=$SAGE_LOCAL
         make install
  • Make and install C++ binary, otwrapper. Binary is copied to $SAGE_LOCAL/bin

    •    cd otwrapper
         make install
