Guido van Rossum1631cbe1996-09-10 18:19:23 +00001# Universal Unix Makefile for Python extensions
2# =============================================

4# Short Instructions
5# ------------------
6
Guido van Rossumbef03ae1997-07-19 22:52:43 +00007# 1. Build and install Python (1.5 or newer).
Guido van Rossum1631cbe1996-09-10 18:19:23 +00008# 2. "make -f Makefile.pre.in boot"
9# 3. "make"
10# You should now have a shared library.

12# Long Instructions
13# -----------------
14
Guido van Rossumbef03ae1997-07-19 22:52:43 +000015# Build *and install* the basic Python 1.5 distribution. See the
16# Python README for instructions. (This version of Makefile.pre.in
17# only withs with Python 1.5, alpha 3 or newer.)
Guido van Rossum1631cbe1996-09-10 18:19:23 +000018
19# Create a file Setup.in for your extension. This file follows the
20# format of the Modules/Setup.in file; see the instructions there.
21# For a simple module called "spam" on file "spammodule.c", it can
22# contain a single line:
23# spam spammodule.c
24# You can build as many modules as you want in the same directory --
25# just have a separate line for each of them in the Setup.in file.
26
27# If you want to build your extension as a shared library, insert a
28# line containing just the string
29# *shared*
30# at the top of your Setup.in file.
31
32# Note that the build process copies Setup.in to Setup, and then works
33# with Setup. It doesn't overwrite Setup when Setup.in is changed, so
34# while you're in the process of debugging your Setup.in file, you may
35# want to edit Setup instead, and copy it back to Setup.in later.
36# (All this is done so you can distribute your extension easily and
37# someone else can select the modules they actually want to build by
38# commenting out lines in the Setup file, without editing the
39# original. Editing Setup is also used to specify nonstandard
40# locations for include or library files.)
41
42# Copy this file (Misc/Makefile.pre.in) to the directory containing
43# your extension.
44
45# Run "make -f Makefile.pre.in boot". This creates Makefile
46# (producing Makefile.pre and sedscript as intermediate files) and
47# config.c, incorporating the values for sys.prefix, sys.exec_prefix
48# and sys.version from the installed Python binary. For this to work,
49# the python binary must be on your path. If this fails, try
Guido van Rossumbef03ae1997-07-19 22:52:43 +000050# make -f Makefile.pre.in Makefile VERSION=1.5 installdir=<prefix>
Guido van Rossum1631cbe1996-09-10 18:19:23 +000051# where <prefix> is the prefix used to install Python for installdir
52# (and possibly similar for exec_installdir=<exec_prefix>).
53
Guido van Rossumbec74841996-11-27 19:38:53 +000054# Note: "make boot" implies "make clobber" -- it assumes that when you
55# bootstrap you may have changed platforms so it removes all previous
56# output files.
57
Guido van Rossum1631cbe1996-09-10 18:19:23 +000058# If you are building your extension as a shared library (your
59# Setup.in file starts with *shared*), run "make" or "make sharedmods"
60# to build the shared library files. If you are building a statically
61# linked Python binary (the only solution of your platform doesn't
62# support shared libraries, and sometimes handy if you want to
63# distribute or install the resulting Python binary), run "make
64# python".
65
66# Note: Each time you edit Makefile.pre.in or Setup, you must run
67# "make Makefile" before running "make".
68
69# Hint: if you want to use VPATH, you can start in an empty
70# subdirectory and say (e.g.):
71# make -f ../Makefile.pre.in boot srcdir=.. VPATH=..
72

77installdir= /usr/local
78
79# The exec_prefix used by the same
80exec_installdir=$(installdir)
81
82# Source directory and VPATH in case you want to use VPATH.

84# automatic support as the Makefile is not generated by
85# config.status.)
