- # 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.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=1.5 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") ===
-
- # The prefix used by "make inclinstall libainstall" of core python
- 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.)
- srcdir= .
- VPATH= .
-
- # === Variables that you may want to customize (rarely) ===
-
- # (Static) build target
- TARGET= python
-
- # Installed python binary (used only by boot target)
- PYTHON= python
-
- # Add more -I and -D options here
- CFLAGS= $(OPT) -I$(INCLUDEPY) -I$(EXECINCLUDEPY) $(DEFS)

- # These two variables can be set in Setup to merge extensions.
- # See example[23].
