Misc/Makefile.pre.in

# Universal Unix Makefile for Python extensions
# =============================================

# Short Instructions
# ------------------

# 1. Build and install Python (1.5 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 1.5 distribution.  See the
# Python README for instructions.  (This version of Makefile.pre.in
# only withs with Python 1.5, alpha 3 or newer.)

# Create a file Setup.in for your extension.  This file follows the
# format of the Modules/Setup.dist 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=1.5 installdir=<prefix>
# where <prefix> is the prefix used to install Python for installdir
# (and possibly similar for exec_installdir=<exec_prefix>).

# Note: "make boot" implies "make clobber" -- it assumes that when you
# bootstrap you may have changed platforms so it removes all previous
# output files.

# 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=..


# === Bootstrap variables (edited through "make boot") ===

installdir=	/usr/local

# The exec_prefix used by the same
exec_installdir=$(installdir)

# Source directory and VPATH in case you want to use VPATH.
# (You will have to edit these two lines yourself -- there is no
# automatic support as the Makefile is not generated by
# config.status.)
