Hi Stefan,
There are no build errors in the warnings module and _warnings.o is
generated.
However I looked at the make log and no _warnings.so is built by the
linker. Instead
_warnings.o is just archived into libpython3.0a.
Cannot find any error in config.log either. I tried to check how
_warnings.so was
built in previous Python versions (<=2.5) but apparently there is no
_warnings.so
in Python 2.5 and earlier, only warnings.py .
I tried to build a _warnings.so manually and then copy it to
lib-dynload folder.
First time it failed with an Import Error.
$gcc -pthread -shared /home/anand/projects/py3k/Python/_warnings.o
-L/usr/local/lib -o build/lib.linux-i686-3.0/_warnings.so
$sudo cp build/lib.linux-i686-3.0/_warnings.so
/usr/local/lib/python3.0/lib-dynload/
[EMAIL PROTECTED] ~]$ python3
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
File "/usr/local/lib/python3.0/io.py", line 63, in <module>
import warnings
File "/usr/local/lib/python3.0/warnings.py", line 268, in <module>
from _warnings import (filters, default_action, once_registry,
ImportError: /usr/local/lib/python3.0/lib-dynload/_warnings.so:
undefined symbol: Py_DisplaySourceLine
Aborted
I figured Py_DisplaySourceLine is present in traceback.o, so did this
(clearly a wrong
way, but just to see if it works...)
$ gcc -pthread -shared /home/anand/projects/py3k/Python/_warnings.o
/home/anand/projects/py3k/Python/traceback.o -L/usr/local/lib -o
build/lib.linux-i686-3.0/_warnings.so
$ sudo cp build/lib.linux-i686-3.0/_warnings.so
/usr/local/lib/python3.0/lib-dynload/
Now it produces this error.
[EMAIL PROTECTED] py3k]$ python3
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
File "/usr/local/lib/python3.0/io.py", line 63, in <module>
import warnings
File "/usr/local/lib/python3.0/warnings.py", line 268, in <module>
from _warnings import (filters, default_action, once_registry,
ImportError: dynamic module does not define init function (init_warnings)
Aborted
Basically, I am stumped at this point. Any help is appreciated.
Regards
