This directory contains various scripts and code to build binaries installers for
windows.
It can:
- prepare a bootstrap environment to build binary in a self-contained
directory
- build binaries for different architectures using different site.cfg
- prepare a nsis-based installer which automatically detects the arch
on the computer where numpy is installed.
Example:
========
python doall.py
Should build the numpy 'super' installer for sse2, sse3 and nosse from scratch.
You have to run it in the win32build directory.
Dependencies:
=============
You need the following to use those scripts:
- python and mingw tools (gcc, make, g77 at least).
- the binaries for atlas/blas/lapack for the various archs supported
(see vendor in numpy repository root for tools to build those).
- python, nsis and subversion command line tools should be in your
PATH, e.g. running python, makensis and svn should work in a DOS
cmd.exe.
- the CpuCaps nsis plugin (see below on how to build it).
Components:
===========
cpuid
-----
cpuid: contains a mini C lib to detect SSE variants (SSE 1, 2 and 3 for now).
It relies on gcc ASM, but porting it to VS should be trivial (only a few lines
os ASM).
cpucaps:
--------
cpucaps: nsis plugin to add the ability to detect SSE for installers, uses
cpuid. To build it, you have two options:
- build it manually: build the CpuCaps.dll with sources cpucaps.c and
cpuid.c in cpuid directory.
- with scons: if you have scons, just do scons install. It will build
and put the CpuCaps.dll in the plugins directory of nsis (if you
install nsis in the default path).
- run build-cpucaps.py with a windows python, e.g.
wine "C:\Python27\python" build-cpucaps.py
build.py:
---------
Can build the binaries for each variant of arch in a bootstrap environment
prepare_bootstrap.py
--------------------
Script to prepare a bootstrap environment. A bootstrap environment depends on
the python version (2.5, 2.4, etc...).
It works by building a source distribution, unzipping it in a bootrap
directory, and putting everything (build.py, nsis script, etc...) in it.
