into Makefile.pre.in; the configure script will only determine the basename
of the file.
This fixes installation of a Python built using C++, reported by Greg
Wilson.
-shared does the following things:
- invoke the linker with -G -dy -z text (the latter only if
-mimpure-text was not given)
- drop crt1.o from the list of objects being linked
- drop -lc from the list of libraries being linked
OTOH, -G is just passed through to the linker.
The things that -shared does are necessary: crt1.o defines _start, and
requires main, so it should not be present in a shared library.
Likewise, -z text should be used to detect position-dependent code at
compile time.
Compile shared object files using -fPIC option when using GCC on Solaris (SF
patch #103865). Closes bug #132783. Move config.c generated by makesetup to
the Modules directory.
- Add CFLAGSFORSHARED variable. configure sets this to CCSHARED if LDLIBRARY
is a shared library.
- Remove -fPIC from OPT, it has no business there.
- Change CCSHARED option for Linux to -fPIC. It should probably be
-fPIC on a few other platforms as well.
- Don't create silly boot Makefile, create Setup files and run makesetup
instead.
- change EXE to EXTEXT, there is an autoconf macro for it
- use PROG_INSTALL macro rather than always using install-sh
- add option to disable signal module (simplifies the makefile)
- create subdirs for object files (when building out of src dir)
- don't generate subdir makefiles
- generate "boot" makefile
by weird and (hopefully) unnecessary SET_CXX and SET_DLLLIBRARY macros
that occurr at the start of Makefile.in files.
- Also removed the already-commented-out SET_CCC macro cruft.
builds during which he forgot to uncomment crucial library lines in
Setup, walks into Guido's East End nightclub with a tactical nuclear
weapon on his shoulder. Said nuclear weapon is promptly deployed
exactly where it will do the most good, right in the middle of
configure.in.
With this patch, the set of libraries autoconfigured in is extended to
include ndbm, gdbm, and crypt. This essentially eliminates any need to
tweak Setup for a normal Linux build.
"'E was a fair man. Cruel, but fair."
when configure detects the presence of termios.h; later we'll use this
for correct configuration of edline/readline.
Also, fix a bug in acconfig.h -- somebody forgot to add an undef to
cover the LIBNDBM configure symbol, which was preventing autoheader
from working properly.
of dbmmodule dynamically by default (otherwise it can pull in
dependencies with libdb that croak pybsddb3). This change moves the
Setup line for dbmmodule to Setup.config.in.
- when compiling with GCC on Solaris, use "$(CC) -shared" instead
of "$(CC) -G" to generate .so files
- when compiling with GCC on any platform, add "-fPIC" to OPT
(without this, "$(CC) -shared" dies horribly)
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.
-Wstrict-prototypes options. This will make it a lot easier to keep
warnings under control in the first place in the future.
There is one known warning at this time, caught by the -Wstrict-prototypes
option. In Modules/main.c, the declaration of getopt() without parameters
gets a complaint (rightly) that it is not a proper prototype. The lack of
a complete prototype information should be corrected when the right
portability conditions have been identified.
Approved by the Guido.
Tony Lownds: [ Patch #101816 ] Fixes shared modules on Mac OS X
1. Mac OS X is recognized by the Next-ish host recognition code as
"Darwin/1.2"
2. When specifying just --with-dyld, modules can compile as shared
3. --with-dyld and --with-next-framework, modules can compile as
shared
4. --with-suffix=.exe, and Lib/plat-darwin1.2 is being made, the regen
script invokes python as python.exe
[I had to reformat this patch a bit to make it work. Please test!]
Dan Wolfe: [ Patch #101823 ] Fix Darwin POSIX Thread redefinition
The patch below fixes the redefinition problem in Darwin with
_POSIX_THREADS. I'm not sure if this is the correct long term fix but
for now it fixes the problem and the fix is specific to Darwin.
Dan Wolfe: [ Patch #101824 ] On Darwin, remove unrecognized option
`-OPT:Olimit=0'
After many, many, many compiles, I finally got itchy of this warning
cluttering up the output... so I scratched (Darwin configs only) and
it's gone! :-)

Apparently, on SunOS 4.1.4_JL (and other?) OSes, -d on an empty string
always returns true. This closes SF bug #115392.
-D_HPUX_SOURCE and also turns on long long support.
Suggestion by stnor@sweden.hp.com (Stefan Norberg).
Please test this if you have access to HP-UX!!!
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.
Changes include:
- There's a --with-pth configure option.
- Instead of _GNU_PTH, we test for HAVE_PTH.
- Better signal handling.
- (The config.h.in file is regenerated in a slightly different order.)
This allows dbmmodule.c to use either without having to add additional
options to the Modules/Setup file or make source changes.
(At least some Linux systems use gdbm to emulate ndbm, but only install
the ndbm.h header as /usr/include/gdbm/ndbm.h.)
enable it), but db.h was not found, the WITH_LIBDB macros was still being
defined, resulting in compilation errors. Also added a short explain when
bsddb support wasn't enabled (because db.h wasn't found) when the user
explicitly used --with-libdb on the configure command line.
Update the build structures to automatically detect the presence of BSD db,
including the proper name of the header file to include. Has all the
expected niceties associated with yet-more-configure-options. ;)
This checkin includes changes for non-generated files only; subsequent
checkin will catch those.
This is part of SourceForge patch #101272.
- Fix bug in thread_pthread.h::PyThread_get_thread_ident() where
sizeof(pthread) < sizeof(long).
- Add 'configure' for:
- SIZEOF_PTHREAD is pthread_t can be included via <pthread.h>
- setting Monterey system name
- appropriate CC,LINKCC,LDSHARED,OPT, and CCSHARED for Monterey
- Add section in README for Monterey build
which I can cast void* to and back again without losing information".
In pyport.h, we typedef Py_uintptr_t to mean this thing, which if the
platform supports, will be uintptr_t (otherwise, other accomodations
are made).
- Don't call both AC_CHECK_FUNCS and AC_REPLACE_FUNC for 'hypot', as the
latter already does everything the former does (because it's implemented as
a call to the former.)
- Don't call AC_CHECK_FUNC() without any 'action' clauses or with an action
clause that just defines HAVE_<function>. Instead, call AC_CHECK_FUNCS,
which defines 'HAVE_<function>' of itself, possibly with aditional 'action'
clauses.
No checks are removed by this patch, only moved around, and some duplicates
are removed.
Patch by Thomas Wouters <thomas@xs4all.net> with small changes of mine
(in main(), use return instead of exit).
Closes patch #100832

disables it. The gc test is moved to just after the thread test, as
is the wctype-functions test.
Modules/Setup.config is generated instead of Modules/Setup.thread.
Applied SF patch #100684 (loewis) to fix help alignment bug.
64-bit readiness (the config values are needed for patches that I will
be submitting later today. The changes are as follows:
- add SIZEOF_OFF_T #define's to PC/config.h (it was already in configure.in)
- add SIZEOF_TIME_T #define to PC/config.h and configure
Needed for some buffer overflow checking because sizeof(time_t) is
different on Win64.
- add SIZEOF_FPOS_T #define
Needed for the Win64 large file support implementation.
- add SIZEOF_HKEY in PC/config.h only
Needed for proper Win32 vs. Win64 handling in PC/winreg.c
- #define HAVE_LARGEFILE_SUPPORT for Win64
- typedef long intptr_t; for all Windows except Win64 (which defines it
itself)
This is a new ANSI (I think) type that is useful (and used by me) for
proper handling in msvcrtmodule.c and posixmodule.c
- indent the nested #ifdef's and #defines in PC/config.h
This is *so* much more readable. There cannot be a compiler
compatibilty issue here can there? Perl uses indented #defines and it
compiles with everything.
threads use --without-threads. No extra tests of thread/compiler
combinations have been added.
--with(out)-thread and --with(out)-threads are completely
interchangeable.
--with-threads still supports the =DIRECTORY option for specifying
where to find thread libraries.
This patch adds the openpty() and forkpty() library calls to posixmodule.c,
when they are available on the target
system. (glibc-2.1-based Linux systems, FreeBSD and BSDI at least, probably
the other BSD-based systems as well.)
Lib/pty.py is also rewritten to use openpty when available, but falls
back to the old SGI method or the "manual" BSD open-a-pty
code. Openpty() is necessary to use the Unix98 ptys under Linux 2.2,
or when using non-standard tty names under (at least) BSDI, which is
why I needed it, myself ;-) forkpty() is included for symmetry.
create shared extensions rather than 'ld -G'. This ensures that shared
extensions link against libgcc.a, in case there are any functions in the
GCC runtime not already in the Python core.
Solaris 2 has stub implementations of the POSIX thread functions such as
pthread_detach in libc. This means that configure tries to use them without
-lpthread, then the test of pthread_create fails and the configuration
falls back to the Solaris thread library. This patch moves the test for
pthread_create in -lpthread ahead of the test for pthread_detach in libc.
The patch also ensures that -lpthread is at the start of the library list
when linking, to pick up POSIX thread semantics for fork (see below).
Justification.
Use of POSIX threads on Solaris ensures that the fork() call only runs the
thread that called fork() in the child. This is desirable to prevent (for
example) parent server or database threads running in the child. Sun's
-lthread library uses a traditional fork() which replicates all the
parent's threads in the child. I find this undesirable.
Digression.
The configure.in seems to always test for -lthread even if a POSIX library
is found. I'm not enough of a configure.in wizard to decide whether this is
desirable or how to fix it. It is also irrelevant to this patch - I just
spotted it while testing.
End of Digression.
least on Solaris (sometimes it's Unix98, sometimes it conforms to an
early draft).
Properly generate config.h.in using autoheader instead of editing it
manually; thanks, Guido!
Duzan, for AIX, to support C++ objects with static initializers, when
using the genuine IBM C++ compiler (namely xlC/xlC_r).
See accompanying patches to acconfig.h and importdl.c.
The following patches (relative to 1.5.2b1) enable Python dynamic
loading to work on NetBSD platforms that use ELF (presnetly mips and
alpha systems). They automaticly determine wether the system is ELF or
a.out rather than using astatic list of platforms so that when other
NetBSD platforms move to ELF, python will continue to work without
change.
Added AC_CHECK_SIZEOF(void *).
Added yet another test for pthreads (pthread_create may be in libc).
Added pthread_init to list of functions whose existence is checked.
(1) reorder the tests for -Olimit 1500 and -OPT:Olimit=0 so that the
latter test is performed first, and if it works, the former test is
skipped. This should get rid of the problem that the new SGI
compilers accept both but emit a warning about -Olimit 1500.
(2) The DGUX hack was somehow split in two by the Olimit tests,
probably as the result of a non-context diff. Moved this back
together again, after the Olimit tests.
it seems harmless for other platforms. It plays tricks with the name
of the library used to link with. Apparently DG/UX really wants a
shared library to link with if it wants shared modules to use symbols
from the library. I'm not sure why this wasn't an issue with 1.4;
DG/UX seems to be the only platform where moving to a single library
made things harder!
BTW This adds a target to create libpython$(VERSION).so; however this
target is *only* for DG/UX.
- add test for strptime (not used by the core but needed by Marc Lemburg's
Date object).
- Test for GNU ld on Solaris; need to add an extra linker option to
export symbols in that case.
enabled. This is done through a substitution in Modules/Setup.thread(.in).
Bill Janssen will be happy. The original idea was by Lele Gaifax (though
I changed the implementation to use a separate file).
from the main program to shared libraries. On mklinux, the old
'-rdynamic' doesn't work; the new '-Xlinker -export-dynamic' works
both there and on Intel Linux platforms.
Makefile.in: run config.status in "make recheck".
configure.in: add test for hypot().
config.h.in, configure: since configure.in changed.
rest: the usual boring stuff.
more trouble than it's worth at CWI and most other people seem to
install Python in the default (/usr/local) anway. Changed comment
