Guido van Rossum	91cb9d2	1995-04-10 11:47:38	[diff] [blame]	52	What is Python anyway?
				53	----------------------
				54
Guido van Rossum	4f40c2d	2000-09-05 16:46:22	[diff] [blame]	55	Python is an interpreted object-oriented programming language suitable
				56	(amongst other uses) for distributed application development,
				57	scripting, numeric computing and system testing. Python is often
				58	compared to Tcl, Perl, Java, JavaScript, Visual Basic or Scheme. To
				59	find out more about what Python can do for you, point your browser to
Guido van Rossum	67345eb	2001-01-18 14:51:12	[diff] [blame]	60	http://www.python.org/.

Guido van Rossum	627b2d7	1993-12-24 10:39:16	[diff] [blame]	154
Guido van Rossum	59b0b60	2002-02-08 22:22:35	[diff] [blame]	155	Before you can build Python, you must first configure it.
				156	Fortunately, the configuration and build process has been automated
				157	for Unix and Linux installations, so all you usually have to do is
				158	type a few commands and sit back. There are some platforms where
				159	things are not quite as smooth; see the platform specific notes below.
				160	If you want to build for multiple platforms sharing the same source
				161	tree, see the section on VPATH below.
Guido van Rossum	627b2d7	1993-12-24 10:39:16	[diff] [blame]	162
Guido van Rossum	59b0b60	2002-02-08 22:22:35	[diff] [blame]	163	Start by running the script "./configure", which determines your
				164	system configuration and creates the Makefile. (It takes a minute or
				165	two -- please be patient!) You may want to pass options to the
				166	configure script -- see the section below on configuration options and
				167	variables. When it's done, you are ready to run make.
Guido van Rossum	6d9cc80	1996-08-01 17:31:22	[diff] [blame]	168
Guido van Rossum	59b0b60	2002-02-08 22:22:35	[diff] [blame]	169	To build Python, you normally type "make" in the toplevel directory.
				170	If you have changed the configuration, the Makefile may have to be
				171	rebuilt. In this case you may have to run make again to correctly
				172	build your desired target. The interpreter executable is built in the
				173	top level directory.
Guido van Rossum	6d9cc80	1996-08-01 17:31:22	[diff] [blame]	174
Guido van Rossum	4f40c2d	2000-09-05 16:46:22	[diff] [blame]	175	Once you have built a Python interpreter, see the subsections below on
Guido van Rossum	59b0b60	2002-02-08 22:22:35	[diff] [blame]	176	testing and installation. If you run into trouble, see the next
				177	section.
				178
				179	Previous versions of Python used a manual configuration process that
				180	involved editing the file Modules/Setup. While this file still exists
				181	and manual configuration is still supported, it is rarely needed any
				182	more: almost all modules are automatically built as appropriate under
				183	guidance of the setup.py script, which is run by Make after the
				184	interpreter has been built.

Guido van Rossum	4952369	1997-08-15 18:30:14	[diff] [blame]	194	http://www.python.org/doc/FAQ.html) for hints on what can go wrong,
				195	and how to fix it.
Guido van Rossum	91cb9d2	1995-04-10 11:47:38	[diff] [blame]	196
Guido van Rossum	6d9cc80	1996-08-01 17:31:22	[diff] [blame]	197	If you rerun the configure script with different options, remove all
				198	object files by running "make clean" before rebuilding. Believe it or
				199	not, "make clean" sometimes helps to clean up other inexplicable
				200	problems as well. Try it before sending in a bug report!
				201
Guido van Rossum	d0fe845	1996-08-26 03:02:37	[diff] [blame]	202	If the configure script fails or doesn't seem to find things that
Guido van Rossum	c0be2f5	1997-10-08 05:05:28	[diff] [blame]	203	should be there, inspect the config.log file. When you fix a
				204	configure problem, be sure to remove config.cache!
				205
				206	If you get a warning for every file about the -Olimit option being no
				207	longer supported, you can ignore it. There's no foolproof way to know
Guido van Rossum	4f40c2d	2000-09-05 16:46:22	[diff] [blame]	208	whether this option is needed; all we can do is test whether it is
Guido van Rossum	c0be2f5	1997-10-08 05:05:28	[diff] [blame]	209	accepted without error. On some systems, e.g. older SGI compilers, it
				210	is essential for performance (specifically when compiling ceval.c,
				211	which has more basic blocks than the default limit of 1000). If the
				212	warning bothers you, edit the Makefile to remove "-Olimit 1500" from
				213	the OPT variable.
Guido van Rossum	d0fe845	1996-08-26 03:02:37	[diff] [blame]	214
Guido van Rossum	7ac1153	2000-08-29 21:36:40	[diff] [blame]	215	If you get failures in test_long, or sys.maxint gets set to -1, you
				216	are probably experiencing compiler bugs, usually related to
Martin v. Löwis	9cea5f5	2002-11-15 07:28:05	[diff] [blame]	217	optimization. This is a common problem with some versions of gcc, and
				218	some vendor-supplied compilers, which can sometimes be worked around
				219	by turning off optimization. Consider switching to stable versions
Anthony Baxter	e9d719b	2004-11-30 01:49:18	[diff] [blame]	220	(gcc 2.95.2, gcc 3.x, or contact your vendor.)
Guido van Rossum	7ac1153	2000-08-29 21:36:40	[diff] [blame]	221
				222	From Python 2.0 onward, all Python C code is ANSI C. Compiling using
				223	old K&R-C-only compilers is no longer possible. ANSI C compilers are
				224	available for all modern systems, either in the form of updated
Martin v. Löwis	9cea5f5	2002-11-15 07:28:05	[diff] [blame]	225	compilers from the vendor, or one of the free compilers (gcc).

				485	there are a few bugs and gotchas. For more information see a
				486	thread on comp.lang.python in May 2002 entitled "Building
				487	Python on Cray T3E".
				488
				489	1) Use Cray's cc and not gcc. The latter was reported not to

				495	MACHDEP=unicosmk
				496
				497	2) Run configure with option "--enable-unicode=ucs4".
				498
				499	3) The Cray T3E does not support dynamic linking, so extension
				500	modules have to be built by adding (or uncommenting) lines
				501	in Modules/Setup. The minimum set of modules is
				502

				505	On NIWA's vanilla T3E system the following have also been

				511	regex, rotor, select, struct, strop, syslog, termios
				512	time, timing, xreadlines
				513
				514	4) Once the python executable and library have been built, make
				515	will execute setup.py, which will attempt to build remaining
				516	extensions and link them dynamically. Each of these attempts
				517	will fail but should not halt the make process. This is
				518	normal.
				519
				520	5) Running "make test" uses a lot of resources and causes
				521	problems on our system. You might want to try running tests

				653
				654	Before building:
				655
				656	Make sure you have shared versions of the libraries you
				657	want to use with Python. You will have to compile them
				658	yourself, or download precompiled packages.
				659
				660	Recommended libraries:
				661
				662	ncurses-4.2
				663	readline-4.2a
				664	zlib-1.1.4
				665
				666	Build:
				667
				668	$ ./configure --prefix=/usr/python
				669	$ make
				670
				671	Python is always built as a shared library, otherwise
				672	dynamic loading would not work.
				673
				674	Testing:
				675
				676	$ make test
				677
				678	Install:
				679
				680	# make install
				681	# pkgmanager -a /usr/python
				682
				683
				684	AtheOS issues:
				685
				686	- large file support: due to a stdio bug in glibc/libio,
				687	access to large files may not work correctly. fseeko()
				688	tries to seek to a negative offset. ftello() returns a
				689	negative offset, it looks like a 32->64bit
				690	sign-extension issue. The lowlevel functions (open,
				691	lseek, etc) are OK.
				692	- sockets: AF_UNIX is defined in the C library and in
				693	Python, but not implemented in the system.
				694	- select: poll is available in the C library, but does not
				695	work (It does not return POLLNVAL for bad fds and
				696	hangs).
				697	- posix: statvfs and fstatvfs always return ENOSYS.
				698	- disabled modules:
				699	- mmap: not yet implemented in AtheOS
				700	- nis: broken (on an unconfigured system
				701	yp_get_default_domain() returns junk instead of
				702	error)
				703	- dl: dynamic loading doesn't work via dlopen()
				704	- resource: getrimit and setrlimit are not yet
				705	implemented
				706
				707	- if you are getting segmentation faults, you probably are
				708	low on memory. AtheOS doesn't handle very well an
				709	out-of-memory condition and simply SEGVs the process.
				710
				711	Tested on:
				712
				713	AtheOS-0.3.7
				714	gcc-2.95
				715	binutils-2.10
				716	make-3.78

				723	<http://pybsddb.sf.net/> was adopted into Python as the bsddb package,

				726	Sleepycat's libraries provide the necessary API, so older versions
				727	aren't supported through this interface. The old bsddb module has
				728	been retained as bsddb185, though it is not built by default. Users
				729	wishing to use it will have to tweak Modules/Setup to build it. The
				730	dbm module will still be built against the Sleepycat libraries if
				731	other preferred alternatives (ndbm, gdbm) are not found, though
				732	versions of the Sleepycat library prior to 3.1 are not considered.

Andrew M. Kuchling	ebe3045	2001-02-27 03:24:24	[diff] [blame]	812	Starting with Python 2.1, the setup.py script at the top of the source
				813	distribution attempts to detect which modules can be built and
				814	automatically compiles them. Autodetection doesn't always work, so
Guido van Rossum	59b0b60	2002-02-08 22:22:35	[diff] [blame]	815	you can still customize the configuration by editing the Modules/Setup
				816	file; but this should be considered a last resort. The rest of this
				817	section only applies if you decide to edit the Modules/Setup file.
				818	You also need this to enable static linking of certain modules (which
				819	is needed to enable profiling on some systems).
				820
Andrew M. Kuchling	ebe3045	2001-02-27 03:24:24	[diff] [blame]	821	This file is initially copied from Setup.dist by the configure script;
				822	if it does not exist yet, create it by copying Modules/Setup.dist
				823	yourself (configure will never overwrite it). Never edit Setup.dist
				824	-- always edit Setup or Setup.local (see below). Read the comments in
				825	the file for information on what kind of edits are allowed. When you
				826	have edited Setup in the Modules directory, the interpreter will
Guido van Rossum	ef67ded	2001-10-05 17:04:42	[diff] [blame]	827	automatically be rebuilt the next time you run make (in the toplevel

Andrew M. Kuchling	ebe3045	2001-02-27 03:24:24	[diff] [blame]	830	Many useful modules can be built on any Unix system, but some optional
				831	modules can't be reliably autodetected. Often the quickest way to
				832	determine whether a particular module works or not is to see if it
				833	will build: enable it in Setup, then if you get compilation or link
Fred Drake	6caae14	2000-10-25 17:51:02	[diff] [blame]	834	errors, disable it -- you're either missing support or need to adjust

				850
Guido van Rossum	6d9cc80	1996-08-01 17:31:22	[diff] [blame]	851	If you want or need to change the optimization/debugging options for
				852	the C compiler, assign to the OPT variable on the toplevel make
				853	command; e.g. "make OPT=-g" will build a debugging version of Python
				854	on most platforms. The default is OPT=-O; a value for OPT in the
				855	environment when the configure script is run overrides this default
				856	(likewise for CC; and the initial value for LIBS is used as the base
				857	set of libraries to link with).

				867	---------
				868
				869	If you want C profiling turned on, the easiest way is to run configure
				870	with the CC environment variable to the necessary compiler
				871	invocation. For example, on Linux, this works for profiling using
				872	gprof(1):
				873
				874	CC="gcc -pg" ./configure
				875
				876	Note that on Linux, gprof apparently does not work for shared
				877	libraries. The Makefile/Setup mechanism can be used to compile and

Guido van Rossum	433c8ad	1994-08-01 12:07:07	[diff] [blame]	1060	Building for multiple architectures (using the VPATH feature)
				1061	-------------------------------------------------------------
				1062
				1063	If your file system is shared between multiple architectures, it
				1064	usually is not necessary to make copies of the sources for each
				1065	architecture you want to support. If the make program supports the
				1066	VPATH feature, you can create an empty build directory for each
				1067	architecture, and in each directory run the configure script (on the
				1068	appropriate machine with the appropriate options). This creates the
				1069	necessary subdirectories and the Makefiles therein. The Makefiles
Guido van Rossum	4f40c2d	2000-09-05 16:46:22	[diff] [blame]	1070	contain a line VPATH=... which points to a directory containing the
Guido van Rossum	d0fe845	1996-08-26 03:02:37	[diff] [blame]	1071	actual sources. (On SGI systems, use "smake -J1" instead of "make" if
				1072	you use VPATH -- don't try gnumake.)
Guido van Rossum	433c8ad	1994-08-01 12:07:07	[diff] [blame]	1073
				1074	For example, the following is all you need to build a minimal Python
				1075	in /usr/tmp/python (assuming ~guido/src/python is the toplevel
				1076	directory and you want to build in /usr/tmp/python):
				1077
				1078	$ mkdir /usr/tmp/python
				1079	$ cd /usr/tmp/python
				1080	$ ~guido/src/python/configure
				1081	[...]
				1082	$ make
				1083	[...]
				1084	$
				1085
Neil Schemenauer	73f8ab2	2001-01-26 22:18:55	[diff] [blame]	1086	Note that configure copies the original Setup file to the build
Guido van Rossum	433c8ad	1994-08-01 12:07:07	[diff] [blame]	1087	directory if it finds no Setup file there. This means that you can
				1088	edit the Setup file for each architecture independently. For this
				1089	reason, subsequent changes to the original Setup file are not tracked
				1090	automatically, as they might overwrite local changes. To force a copy
				1091	of a changed original Setup file, delete the target Setup file. (The
				1092	makesetup script supports multiple input files, so if you want to be
				1093	fancy you can change the rules to create an empty Setup.local if it
				1094	doesn't exist and run it with arguments $(srcdir)/Setup Setup.local;
				1095	however this assumes that you only need to add modules.)

				1113
				1114	Of course, there are also binary distributions available for these

				1117	To port Python to a new non-UNIX system, you will have to fake the
				1118	effect of running the configure script manually (for Mac and PC, this
				1119	has already been done for you). A good start is to copy the file
Michael W. Hudson	be6e0f4	2002-06-23 16:29:36	[diff] [blame]	1120	pyconfig.h.in to pyconfig.h and edit the latter to reflect the actual
Guido van Rossum	433c8ad	1994-08-01 12:07:07	[diff] [blame]	1121	configuration of your system. Most symbols must simply be defined as
				1122	1 only if the corresponding feature is present and can be left alone
Michael W. Hudson	be6e0f4	2002-06-23 16:29:36	[diff] [blame]	1123	otherwise; however the *_t type symbols must be defined as some
				1124	variant of int if they need to be defined at all.

				1171	module. In order to find the C _tkinter module, it must be compiled
				1172	and linked into the Python interpreter -- the setup.py script does
				1173	this. In order to find the Python Tkinter module, sys.path must be
				1174	set correctly -- normal installation takes care of this.
