Summary: Missing Library Modules

Initial Comment:
downloaded python-2.4.2 under redhat Linux 9

python


>>> import time
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named time
>>> import math
Traceback (most recent call last):

Haven't checked many more  modules

didn't notice any errors in ./config, make, or make
install.

ran strace and the source was staring at me in two
uncorrelated places;

1)
PYTHONPATH 
.:/usr/local/lib/python2.4/:/usr/local/lib/python2.4/site-packages/
2)
[root at localhost Python-2.4.2]# find / -name 'time.so'
/usr/local/lib/python2.4/lib-dynload/time.so

appending '/usr/local/lib/python2.4/lib-dynload' resolved
the problem

thanks for the hint

The files (time.so, math.so) look like they are installed
where they should be.  What is your LD_LIBRARY_PATH?  Does
it work as a normal user (not root)?  ls -l
/usr/local/lib/python2.4/lib-dynload/math.so ?

Finally, this is the most likely to help you resolve the
problem, run strace.  strace will show where python is
trying to load math.so and should indicate what error is
occurring.  Hopefully, that will point out the real problem.

I did a make clean, ./configure, make, and make install with
no improvements. 

Here is the contnts of  the file previously attached.  I
think it answers the questions.

.:/usr/local/lib/python2.4/:/usr/local/lib/python2.4/site-packages/
PYTHON PATH seems OK

[root at localhost Python-2.4.2]# echo $PYTHONPATH
.:/usr/local/lib/python2.4/:/usr/local/lib/python2.4/site-packages/
[root at localhost Python-2.4.2]#



There were some warning during make:

[root at localhost Python-2.4.2]# make >makeInfo

Can you re-run make and see if there are errors?  Is there
anything in your PYTHONPATH environment variable?  We will
need more information in order to attempt to debug this.

Do the .so files exist under build/lib*2.4/ ?
