Unsupported systems
|
||||
-------------------
|
||||
|
||||
A number of features are not supported in Python 2.3 anymore. Some
|
||||
support code is still present, but will be removed in Python 2.4.
|
||||
If you still need to use current Python versions on these systems,
|
||||
please send a message to python-dev@python.org indicating that you
|
||||
volunteer to support this system.
|
||||
|
||||
More specifically, the following systems are not supported any
|
||||
longer:
|
||||
- SunOS 4
|
||||
- DYNIX
|
||||
- dgux
|
||||
- Minix
|
||||
- Irix 4 and --with-sgi-dl
|
||||
- Linux 1
|
||||
- Systems defining __d6_pthread_create (configure.in)
|
||||
- Systems defining PY_PTHREAD_D4, PY_PTHREAD_D6,
|
||||
or PY_PTHREAD_D7 in thread_pthread.h
|
||||
- Systems using --with-dl-dld
