 Python for BeOS R5

! To build,

! 1) ./configure --prefix=/boot/home/config

! 2) edit Modules/Setup
! comment out grp and mmap, and pwd on 4.5 or earlier
! uncomment any modules you want to include in python
! (you can also add them later as shared libraries.)
 3) make

 Test:

 make test

! [Chris Herborth writes:]
! test_popen2 will probably hang; it's deadlocked on a semaphore. I should
! probably disable popen2 support... it uses fork(), and fork() doesn't mix
! with threads on BeOS. In *THEORY* you could use it in a single-threaded
! program, but I haven't tried.
! 
! If test_popen2 does hang, you can find the semaphore it's hung on via the
! "ps" command. Look for python and you'll find something like this:
! 
! ./python -tt ../src/Lib/test/regrtest.py (team 26922) (uid 0) (gid 0)
! 39472 python sem 10 3785 1500 piperd(360526)
! ./python -tt ../src/Lib/test/regrtest.py (team 26923) (uid 0) (gid 0)
! 39477 python sem 10 25 4 python lock (1)(360022)
! ^^^^^^
! That last number is the semaphore the fork()'d python is stuck on
! (see how it's helpfully called "python lock (1)"? :-). You can unblock
! that semaphore to let the tests continue using the "release" command
! with that semaphore number. Be _very_ careful with "release" though,
! releasing the wrong semaphore can be hazardous.
! 
! Expect the following errors:
! 
! test * skipped -- an optional feature could not be imported (you'll see
! quite a few of these, based on what optional modules
! you've included)
! 
! test test_fork1 skipped -- can't mix os.fork with threads on BeOS
! 
! test test_select crashed -- select.error : (-2147459072, 'Bad file
! descriptor')
! 
! test test_socket crashed -- exceptions.AttributeError : SOCK_RAW
! 
! These are all due to either partial support for certain things (like
! sockets), or valid differences between systems.
! 
! test 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.

 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.

 make install

- 
- Using GNU readline:
- 
- The Python interpreter is much nicer to work with interactively if
- you've got readline installed. Highly recommended.
- 
- You can get the original GNU readline 2.2 source code from your
- favourite GNU software repository, such as
- ftp://prep.ai.mit.edu/pub/gnu/.
- 
- You can get the only-slightly-modified-for-BeOS version of GNU
- readline 2.2 from the GeekGadgets repository;
- ftp://ftp.ninemoons.com/pub/geekgadgets/.
- 
- 
- Building libreadline for BeOS hosts:
- 
- Note that we don't build a shared library version of libreadline and
- libhistory. That's left as an exercise for the reader.
- 
- You won't be able to link against libreadline.a using the limited
- linker.
- 
- 1) If you're on a PowerPC system, install the POSIX ar from 
- http://www.qnx.com/~chrish/Be/software/index.html#programming
- (note that it's currently packaged with Python, in the BeOS/ar-1.1
- directory).
- 
- If you're on an x86 system, you can leave out the "AR=ar-posix"
- part of the following instructions. In fact, you'll have to...
- 
- 2) For PowerPC, configure with:
- 
- CC=mwcc CFLAGS="-O7 -i- -I." AR=ar-posix RANLIB=: ./configure --verbose \
- --without-gcc --prefix=/boot/home/config powerpc-*-beos
- 
- For x86, configure with:
- 
- CC=mwcc CFLAGS="-O2 -i- -I." RANLIB=: ./configure --verbose \
- --without-gcc --prefix=/boot/home/config x86-*-beos
- 
- Don't worry about the warnings/errors configure spews for
- powerpc-*-beos or x86-*-beos; readline doesn't actually use this host 
- information for anything, although configure will die if you don't 
- specify it.
- 
- 3) Edit config.h to comment out "#define HAVE_SELECT 1"; select() on
- BeOS doesn't work on file descriptors (such as stdin).
- 
- 4) For PowerPC, make with:
- 
- make AR=ar-posix 
- 
- For x86, make with:
- 
- make
- 
- 5) Install with:
- 
- make install
- 
- Enjoy!
