# Universal Unix Makefile for Python extensions
|
||||
# =============================================
|
||||
|
||||
# Short Instructions
|
||||
# ------------------
|
||||
|
||||
# 1. Build and install Python (1.4 or newer).
|
||||
# 2. "make -f Makefile.pre.in boot"
|
||||
# 3. "make"
|
||||
# You should now have a shared library.
|
||||
|
||||
# Long Instructions
|
||||
# -----------------
|
||||
|
||||
# Build *and install* the basic Python 1.4 distribution. See the
|
||||
# Python README for instructions.
|
||||
|
||||
# Create a file Setup.in for your extension. This file follows the
|
||||
# format of the Modules/Setup.in file; see the instructions there.
|
||||
# For a simple module called "spam" on file "spammodule.c", it can
|
||||
# contain a single line:
|
||||
# spam spammodule.c
|
||||
# You can build as many modules as you want in the same directory --
|
||||
# just have a separate line for each of them in the Setup.in file.
|
||||
|
||||
# If you want to build your extension as a shared library, insert a
|
||||
# line containing just the string
|
||||
# *shared*
|
||||
# at the top of your Setup.in file.
|
||||
|
||||
# Note that the build process copies Setup.in to Setup, and then works
|
||||
# with Setup. It doesn't overwrite Setup when Setup.in is changed, so
|
||||
# while you're in the process of debugging your Setup.in file, you may
|
||||
# want to edit Setup instead, and copy it back to Setup.in later.
|
||||
# (All this is done so you can distribute your extension easily and
|
||||
# someone else can select the modules they actually want to build by
|
||||
# commenting out lines in the Setup file, without editing the
|
||||
# original. Editing Setup is also used to specify nonstandard
|
||||
# locations for include or library files.)
|
||||
|
||||
# Copy this file (Misc/Makefile.pre.in) to the directory containing
|
||||
# your extension.
|
||||
|
||||
# Run "make -f Makefile.pre.in boot". This creates Makefile
|
||||
# (producing Makefile.pre and sedscript as intermediate files) and
|
||||
# config.c, incorporating the values for sys.prefix, sys.exec_prefix
|
||||
# and sys.version from the installed Python binary. For this to work,
|
||||
# the python binary must be on your path. If this fails, try
|
||||
# make -f Makefile.pre.in Makefile VERSION=1.4 installdir=<prefix>
|
||||
# where <prefix> is the prefix used to install Python for installdir
|
||||
# (and possibly similar for exec_installdir=<exec_prefix>).
|
||||
|
||||
# If you are building your extension as a shared library (your
|
||||
# Setup.in file starts with *shared*), run "make" or "make sharedmods"
|
||||
# to build the shared library files. If you are building a statically
|
||||
# linked Python binary (the only solution of your platform doesn't
|
||||
# support shared libraries, and sometimes handy if you want to
|
||||
# distribute or install the resulting Python binary), run "make
|
||||
# python".
|
||||
|
||||
# Note: Each time you edit Makefile.pre.in or Setup, you must run
|
||||
# "make Makefile" before running "make".
|
||||
|
||||
# Hint: if you want to use VPATH, you can start in an empty
|
||||
# subdirectory and say (e.g.):
|
||||
# make -f ../Makefile.pre.in boot srcdir=.. VPATH=..

|
||||
exec_installdir=$(installdir)

||||

# Source directory and VPATH in case you want to use VPATH.

# automatic support as the Makefile is not generated by
|

# config.status.)
