Guido van Rossum76be6ed1995-01-02 18:33:54 +00001Python release 1.2
2==================
Guido van Rossum627b2d71993-12-24 10:39:16 +00003
Guido van Rossum76be6ed1995-01-02 18:33:54 +00004==> This version provides new functionality as well as bug fixes.
5 Everyone should upgrade. For a description of what's changed, see
6 Misc/NEWS.
Guido van Rossum627b2d71993-12-24 10:39:16 +00007
Guido van Rossum433c8ad1994-08-01 12:07:07 +00008==> If you don't know yet what Python is: it's an interpreted,
9 extensible, embeddable, interactive, object-oriented programming
10 language. For a quick summary of what Python can mean for a
11 UNIX/C programmer, read Misc/BLURB.LUTZ.
Guido van Rossum627b2d71993-12-24 10:39:16 +000012
Guido van Rossumb85ae1a1994-10-06 16:15:09 +000013==> If you want to start compiling right away (on UNIX): just type
14 "./configure" in the current directory and when it finishes, type
15 "make". See the section Build Instructions below for more
16 details.
Guido van Rossum627b2d71993-12-24 10:39:16 +000017
Guido van Rossum433c8ad1994-08-01 12:07:07 +000018==> All documentation is in the subdirectory Doc in the form of LaTeX
19 files. In order of importance for new users: Tutorial (tut),
20 Library Reference (lib), Language Reference (ref), Extending
21 (ext). Note that especially the Library Reference is of immense
22 value since much of Python's power (including the built-in data
Guido van Rossumb85ae1a1994-10-06 16:15:09 +000023 types and functions!) is described there. [NB The ext document
Guido van Rossum433c8ad1994-08-01 12:07:07 +000024 has not been updated to reflect this release yet.]
Guido van Rossum627b2d71993-12-24 10:39:16 +000025
Guido van Rossum433c8ad1994-08-01 12:07:07 +000026==> Python is COPYRIGHTED but free to use for all. See the copyright
Guido van Rossumb85ae1a1994-10-06 16:15:09 +000027 notice at the end of this file. Moreover, the Python distribution
28 is not affected by the GNU Public Licence (GPL). There is support
29 for interfaces to some GNU code but this is entirely optional and
30 no GNU code is distributed with Python. For all these packages,
31 GPL-free public domain versions also exist.

Guido van Rossum433c8ad1994-08-01 12:07:07 +000034Build instructions
35------------------
Guido van Rossum627b2d71993-12-24 10:39:16 +000036
Guido van Rossum433c8ad1994-08-01 12:07:07 +000037Before you start building Python, you must first configure it. This
38entails (at least) running the script "./configure", which figures out
39your system configuration and creates several Makefiles. (This will
40take a minute or two -- please be patient!) When it is done, you are
41ready to run make. Typing "make" in the toplevel directory will
42recursively run make in each of the subdirectories Parser, Objects,
43Python and Modules, creating a library file in each one. The
44executable of the interpreter is built in the Modules subdirectory but
45moved up here when it is built. If you want or need to, you can also
46chdir into each subdirectory in turn and run make there manually
47(do the Modules subdirectory last!). If you run into trouble, first
48see the section Troubleshooting later in this file.
Guido van Rossum627b2d71993-12-24 10:39:16 +000049
Guido van Rossum433c8ad1994-08-01 12:07:07 +000050AIX users: read the file Misc/AIX-NOTES before trying to build.
Guido van Rossum627b2d71993-12-24 10:39:16 +000051
Guido van Rossum0a516c91994-09-12 10:58:40 +000052HP-UX users: read the file Misc/HPUX-NOTES if you want to be able to
53use shared libraries for dynamically loaded modules.
54
Guido van Rossum433c8ad1994-08-01 12:07:07 +000055Minix users: when using ack, use "CC=cc AR=aal RANLIB=: ./configure"!
Guido van Rossum627b2d71993-12-24 10:39:16 +000056
Guido van Rossum19e0c261995-01-17 16:36:34 +000057NeXT users: try running the configure script with the "--without-gcc"
58option. (The NeXT C compiler is based on gcc, but it is better
59matched to the set of header files provided by NeXT.)
60
Guido van Rossum433c8ad1994-08-01 12:07:07 +000061You can configure the interpreter to contain fewer or more built-in
62modules by editing the file Modules/Setup. This file is initially
63copied (when the toplevel Makefile makes Modules/Makefile for the
64first time) from Setup.in; if it does not exist yet, make a copy
65yourself. Never edit Setup.in -- always edit Setup. Read the
66comments in the file for information on what kind of edits you can
67make. When you have edited Setup, Makefile and config.c in Modules
68will automatically be rebuilt the next time you run make in the
Guido van Rossum9444ce01994-10-20 22:10:23 +000069toplevel directory.
Guido van Rossum627b2d71993-12-24 10:39:16 +000070
Guido van Rossum433c8ad1994-08-01 12:07:07 +000071If you want to change the optimization level of the build, assign to
72the OPT variable on the toplevel make command; e.g. "make OPT=-g" will
Guido van Rossumc561e5d1994-08-23 13:52:46 +000073build a debugging version of Python on most platforms. The default is
74OPT=-O; a value for OPT in the environment when the configure script
75is run overrides this default (likewise for CC; and the initial value
76for LIBS is used as the base set of libraries to link with).
Guido van Rossum433c8ad1994-08-01 12:07:07 +000077
78To test the interpreter that you have just built, type "make test".
79This runs the test set silently, twice (once with no compiled files,
80once with the compiled files left by the previous test run). Each
81test run should print "All tests OK." and nothing more. (The test set
82does not test the built-in modules, but will find most other problems
83with the interpreter.)
84
85To install the interpreter as /usr/local/bin/python, type "make
86install". To install the library as /usr/local/lib/python, type "make
87libinstall". To install the manual page as
88/usr/local/man/man1/python.1, type "make maninstall". To install the
89Emacs editing mode for python, manually copy the file
90Misc/python-mode.el to your local Emacs lisp directory. The directory
91/usr/local can be overridden at configuration time by passing
92--prefix=DIRECTORY to the configure script, or at make time by passing
93"prefix=DIRECTORY" to make. See below for more information on --prefix.
94
95If you plan to do development of extension modules or to embed Python
96in another application and don't want to reference the original source
97tree, you can type "make inclinstall" and "make libainstall" to
98install the include files and lib*.a files, respectively, as
99/usr/local/include/Py/*.h and /usr/local/lib/python/lib/lib*.a. The
100make libainstall target also installs copies of several other files
101used or produced during the build process which are needed to build
102extensions or to generate their Makefiles.
103
104To print the documentation, cd into the Doc subdirectory, type "make"
105(let's hope you have LaTeX installed!), and send the four resulting
106PostScript files (tut.ps, lib.ps, ref.ps, and ext.ps) to the printer.
107See the README file there; you can also build a texinfo version of the
108library manual and from that construct an Emacs info version (the
109hypertext format used by the Emacs "info" command) and an HTML version
110(the hypertext format used by the World Wide Web distributed
111information initiative). You don't need to have LaTeX installed for
112this. Note that the Python archive sites also carry the resulting
113PostScript files, in case you have a PostScript printer but not LaTeX.
114
115Some special cases are handled by passing environment variables or
116options to the configure script:
117
118- The configure script uses gcc (the GNU C compiler) if it finds it.
119If you don't want this, or if this compiler is installed but broken on
Guido van Rossumd626da81995-01-12 12:24:52 +0000120your platform, pass the option --without-gcc. You can also pass
121"CC=cc" (or whatever the name of the proper C compiler is) in the
122environment, but the advantage of using --without-gcc is that this
123option is remembered by the config.status script for its --recheck
124option.
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000125
Guido van Rossum76be6ed1995-01-02 18:33:54 +0000126- On SCO, a number of notes apply:
127
128 1) Everything works much better if you add -U__STDC__ to the
129 defs. This is because all the SCO header files are broken.
130 Anything that isn't mentioned in the C standard it's
131 conditionally excluded when __STDC__ is defined.
132
133 2) Due to the U.S. export restrictions, SCO broke the crypt
134 stuff out into a separate library, libcrypt_i.a so the LIBS
135 needed be set to:
136
137 LIBS=' -lsocket -lcrypt_i'
138
139
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000140- If you want to install the binaries and the Python library somewhere
141else than in /usr/local/{bin,lib}, you can pass the option
142--prefix=DIRECTORY; the interpreter binary will be installed as
143DIRECTORY/bin/python and the library files as DIRECTORY/lib/python/*.
144If you pass --exec-prefix=DIRECTORY (as well) this overrides the
145installation prefix for architecture-dependent files (like the
146interpreter binary). Note that --prefix=DIRECTORY also affects the
147default module search path (sys.path), when Modules/config.c is
148compiled. Passing make the option prefix=DIRECTORY (and/or
149exec_prefix=DIRECTORY) overrides the prefix set at configuration time;
150this may be more convenient than re-running the configure script if
151you change your mind about the install prefix...
152
Guido van Rossum03d8f741994-08-12 12:45:02 +0000153- You can use the GNU readline library to improve the interactive user
154interface: this gives you line editing and command history when
155calling python interactively. You need to configure build the GNU
156readline library before running the configure script. Its sources are
Guido van Rossumb85ae1a1994-10-06 16:15:09 +0000157not distributed with Python; you can ftp them from any GNU mirror
158site, or from its home site:
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000159<URL:ftp://slc2.ins.cwru.edu/pub/dist/readline-2.0.tar.gz> (or a
160higher version number -- using version 1.x is not recommended).
Guido van Rossumb85ae1a1994-10-06 16:15:09 +0000161
162A GPL-free version was posted to comp.sources.misc in volume 31 and is
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000163widely available from FTP archive sites, e.g.
164<URL:ftp://gatekeeper.dec.com/.b/usenet/comp.sources.misc/volume31/editline/part01.Z>
Guido van Rossumb85ae1a1994-10-06 16:15:09 +0000165
166Pass the Python configure script the option --with-readline=DIRECTORY
167where DIRECTORY is the absolute pathname of the directory where you've
168built the readline library. Some hints on building and using the
169readline library:
Guido van Rossum03d8f741994-08-12 12:45:02 +0000170
171 - On SGI IRIX 5, you may have to add the following
172 to rldefs.h:
173
174 #ifndef sigmask
175 #define sigmask(sig) (1L << ((sig)-1))
176 #endif
177
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000178 - On most systems, you will have to add #include "rldefs.h" to the
179 top of several source files, and if you use the VPATH feature, you
180 will have to add dependencies of the form foo.o: foo.c to the
181 Makefile for several values of foo.
182
Guido van Rossum03d8f741994-08-12 12:45:02 +0000183 - The readline library requires use of the termcap library. A
184 known problem with this is that it contains entry points which
185 cause conflicts with the STDWIN and SGI GL libraries. The stdwin
186 conflict can be solved (and will be, in the next release of
187 stdwin) by adding a line saying '#define werase w_erase' to the
188 stdwin.h file (in the stdwin distribution, subdirectory H). The
189 GL conflict has been solved in the Python configure script by a
190 hack that forces use of the static version of the termcap library.
191
192 - Check the newsgroup gnu.bash.bugs for specific problems with the
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000193 readline library (I don't get this group here but I've been told
194 that it is the place for readline bugs.)
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000195
196- On SGI IRIX, and on Sun SOLARIS 2, you can use multiple threads. To
197enable this, pass --with-thread. In the Modules/Setup file, enable
198the thread module. (Threads aren't enabled automatically because
199there are run-time penalties when support for them is compiled in even
200if you don't use them.)
201
202- On SGI IRIX, there are modules that interface to many SGI specific
203system libraries, e.g. the GL library and the audio hardware. To
204enable these modules, you must edit the Modules/Setup file (or copy the
205Setup.irix4 file to it).
206
207- On SGI IRIX 4, dynamic loading of extension modules is supported by
208the "dl" library by Jack Jansen, which is ftp'able from
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000209<URL:ftp://ftp.cwi.nl/pub/dynload/dl-1.6.tar.Z>. This is enabled
210(after you've ftp'ed and compiled the dl library!) by passing
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000211--with-sgi-dl=DIRECTORY where DIRECTORY is the absolute pathname of
212the dl library. (Don't bother on IRIX 5, it already has dynamic
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000213linking using SunOS style shared libraries.) Support for this feature
214is deprecated.
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000215
216- Dynamic loading of modules is rumoured to be supported on some other
217systems: VAX (Ultrix), Sun3 (SunOS 3.4), Sequent Symmetry (Dynix), and
218Atari ST. This is done using a combination of the GNU dynamic loading
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000219package (<URL:ftp://ftp.cwi.nl/pub/dynload/dl-dld-1.1.tar.Z>) and an
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000220emulation of the SGI dl library mentioned above (the emulation can be
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000221found at <URL:ftp://ftp.cwi.nl/pub/dynload/dld-3.2.3.tar.Z>). To enable
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000222this, ftp and compile both libraries, then call the configure passing
223it the option --with-dl-dld=DL_DIRECTORY,DLD_DIRECTORY where
224DL_DIRECTORY is the absolute pathname of the dl emulation library and
225DLD_DIRECTORY is the absolute pathname of the GNU dld library. (Don't
226bother on SunOS 4 or 5, they already have dynamic linking using shared
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000227libraries.) Support for this feature is deprecated.
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000228
229- It is possible to specify alternative versions for the Math library
230(default -lm) and the C library (default the empty string) using the
231options --with-libm=STRING and --with-libc=STRING, respectively. E.g.
232if your system requires that you pass -lc_s to the C compiler to use
233the shared C library, you can pass --with-libc=-lc_s. These libraries
234are passed after all other libraries, the C library last.
235
236You can also build an "extended" interpreter, using modules that are
237not contained in the Modules directory. Extensions are distributed as
238a separate tar file (currently extensions.tar.Z). See the README file
239there.
240
241
Guido van Rossumaf5b83e1995-01-04 19:02:35 +0000242The Tk extension
243----------------
244
245Tk (the user interface component of John Ousterhout's Tcl language) is
246also usable from Python. Since this requires that you first build and
247install Tcl/Tk, the Tk interface is not enabled by default. It
248requires Tcl 7.3 and Tk 3.6. For more info about Tk, including
249pointers to the source, see John Ousterhout's home page at
250<URL:http://playground.sun.com/~ouster/>.
251
252To enable the Python/Tk interface, once you've built and installed
253Tcl/Tk, all you need to do is edit two lines in Modules/Setup; search
254for the string "Tk". Un-comment one (normally the first) of the lines
255beginning with "#tkinter" and un-comment the line beginning with
256"#TKPATH". (If you have installed Tcl/Tk in unusual places you will
257have to edit the first line as well to fix the -I and -L options.)
258See the Build Instructions above for more details.
259
260There is little documentation. Begin with fetching the "Tk Lifesaver"
261document, e.g. <URL:ftp://ftp.cwi.nl/pub/python/tkinter-doc.tar.gz> (a
262gzipped tar file containing a PostScript file). There are demos in
263the Demo/tkinter directory, in the subdirectories guido, matt and www.
264
265Note that there's a Python module called "Tkinter" (capital T) which
266lives in Lib/tkinter/Tkinter.py, and a C module called "tkinter"
267(lower case t) which lives in Modules/tkintermodule.c. Demos and
268normal Tk applications only import the Python Tkinter module -- only
269the latter uses the C tkinter module directly. In order to find the C
270tkinter module, it must be compiled and linked into the Python
271interpreter -- the tkinter line in the Setup file does this. In order
272to find the Python Tkinter module, sys.path must be set correctly --
273the TKPATH assignment in the Setup file takes care of this, but only
274if you install Python properly ("make install libinstall"). (You can
275also use dynamic loading for the C tkinter module, in which case you
276must manually fix up sys.path or set $PYTHONPATH for the Python
277Tkinter module.)
278
279
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000280Building for multiple architectures (using the VPATH feature)
281-------------------------------------------------------------
282
283If your file system is shared between multiple architectures, it
284usually is not necessary to make copies of the sources for each
285architecture you want to support. If the make program supports the
286VPATH feature, you can create an empty build directory for each
287architecture, and in each directory run the configure script (on the
288appropriate machine with the appropriate options). This creates the
289necessary subdirectories and the Makefiles therein. The Makefiles
290contain a line VPATH=... which points to directory containing the
Guido van Rossum6b111b01994-10-11 15:03:34 +0000291actual sources. (On SGI systems, use "smake" instead of "make" if you
292use VPATH -- don't try gnumake.)
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000293
294For example, the following is all you need to build a minimal Python
295in /usr/tmp/python (assuming ~guido/src/python is the toplevel
296directory and you want to build in /usr/tmp/python):
297
298 $ mkdir /usr/tmp/python
299 $ cd /usr/tmp/python
300 $ ~guido/src/python/configure
301 [...]
302 $ make
303 [...]
304 $
305
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000306Note that Modules/Makefile copies the original Setup file to the build
307directory if it finds no Setup file there. This means that you can
308edit the Setup file for each architecture independently. For this
309reason, subsequent changes to the original Setup file are not tracked
310automatically, as they might overwrite local changes. To force a copy
311of a changed original Setup file, delete the target Setup file. (The
312makesetup script supports multiple input files, so if you want to be
313fancy you can change the rules to create an empty Setup.local if it
314doesn't exist and run it with arguments $(srcdir)/Setup Setup.local;
315however this assumes that you only need to add modules.)
316
317
318Troubleshooting
319---------------
320
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000321See section 3 of the FAQ (in subdirectory Misc of the distribution)
322for hints on what can go wrong, and how to fix it.
Guido van Rossum433c8ad1994-08-01 12:07:07 +0000323
324
325Building on non-UNIX systems
326----------------------------
327
328On non-UNIX systems, you will have to fake the effect of running the
329configure script manually. A good start is to copy the file
330config.h.in to config.h and edit the latter to reflect the actual
331configuration of your system. Most symbols must simply be defined as
3321 only if the corresponding feature is present and can be left alone
333otherwise; however RETSIGTYPE must always be defined, either as int or
334as void, and the *_t type symbols must be defined as some variant of
335int if they need to be defined at all. Then arrange that the symbol
336HAVE_CONFIG_H is defined during compilation (usually by passing an
337argument of the form `-DHAVE_CONFIG_H' to the compiler, but this is
338necessarily system-dependent).
339
Guido van Rossumc561e5d1994-08-23 13:52:46 +0000340I have tried to collect instructions, Makefiles and additional sources
341for various platforms in this release. The following directories
342exist:
343
344Mac/ Apple Macintosh, using THINK C 6.0 or MPW 3.2.
345Dos/ MS-DOS and Windows 3.1, using Microsoft C.
346Nt/ Windows NT, using Microsoft Visual C/C++.
347Os2/ OS/2.
348
349Most of these instructions were last tested with a previous Python
350release, so you may still experience occasional problems. If you have
351fixes or suggestions, please let me know and I'll try to incorporate
