The embedded 40250 script layer needs its own interpreter on five platforms. 2.7 is end-of-life, so nothing can be fetched from the target SDKs and the source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for step 3's python27.zip). cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly the 133 objects the reference libpython2.7.a contains, off by default behind -DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table (config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is not, so each platform keeps its own under config/<platform>/, regenerated by tools/py_embed/gen_pyconfig.sh and checked against the shared table. Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac learn arm64 on macOS, and posixmodule.c undefines the process-control calls it hard-defines past pyconfig.h when building for iOS. macOS (ctest python.embed: every builtin imports, codecs and pickle work off the vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and Windows needs a MinGW-vs-MSVC decision; both are noted for step 4. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Python for BeOS R5
|
|
|
|
In Python-2.1, the standard version of the new setup.py program
|
|
will not build the full complement of modules on BeOS. Instead,
|
|
please replace it with the special BeOS version in Misc/BeOS-setup.py.
|
|
|
|
To build,
|
|
|
|
1) cp Misc/BeOS-setup.py setup.py
|
|
2) ./configure --prefix=/boot/home/config
|
|
3) make
|
|
|
|
The modules will all build, except termios which assumes some flags
|
|
we don't have. Put a libreadline.a in /boot/home/config/lib to get
|
|
a readline.so for your interactive editing convenience; NB, not
|
|
libreadline.so, you want to link a static readline library into the
|
|
dynamically loaded Python module.
|
|
|
|
Test:
|
|
|
|
make test
|
|
|
|
The BeOS is Not UNIX category:
|
|
- test_select crashed -- select.error : (-2147459072, 'Bad file descriptor')
|
|
- test_socket crashed -- exceptions.AttributeError : SOCK_RAW
|
|
- test_fcntl crashed -- exceptions.IOError: [Errno -2147483643] Invalid argument
|
|
|
|
This one is funny! BeOS does support large files, and that's why
|
|
we get this error: the file is too big for my filesystem!
|
|
- test_largefile crashed -- exceptions.IOError: [Errno -2147459065]
|
|
No space left on device
|
|
|
|
- test_pickle crashed. This is apparently a serious problem, "complex"
|
|
number objects reconstructed from a pickle don't compare equal to
|
|
their ancestors. But it happens on BeOS PPC only, not Intel.
|

Install:
|
|
|
|
make install
|

Maintainer: None (please volunteer if you would like to see this port continue
|
|
to exist!)
