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
|
|
|

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.

Install:
|
|
|
|
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!
