New submission from Jean Brouwers <[EMAIL PROTECTED]>:
The multiprocessing module fails to build on Solaris 10 when using the
Sun C compiler. The failure is due to one missing symbol
SEM_VALUE_MAX.
Defining that symbol (e.g. as _POSIX_SEM_VALUE_MAX) builds the
_multiprocessing module for both 32- and 64-bit.
However, for 32-bit, 5 tests from test_multiprocessing fail due to the
missing _ctypes module. For 64-bit, the first 3 tests fail (like for
32-bit) but the 4th test hangs. Here is a log:
./python Lib/test/test_multiprocessing.py
test_array (__main__.WithProcessesTestArray) ... ERROR
test_getobj_getlock_obj (__main__.WithProcessesTestArray) ... ERROR
test_rawarray (__main__.WithProcessesTestArray) ... ERROR
