[Swig-user] Attribute Error for python module

[Diptanshu Jamgade]

Hello,
My name is Diptanshu. I am presently working with CCExtractor on a project
of developing python extension module and I am enrolled in GSOC 2017.
For generating the python modules, I tried to take up SWIG but I am
presently having trouble. You can find my interface file at
https://github.com/Diptanshu8/ccextractor/blob/gsoc_work_bento_16_library/linux/ccextractorapi.i
. The corresponding C code is available at
https://github.com/Diptanshu8/ccextractor/blob/gsoc_work_bento_16_library/src/ccextractorapi.c
and the respective header file at
https://github.com/Diptanshu8/ccextractor/blob/gsoc_work_bento_16_library/src/ccextractorapi.h
. Now the generated wrapper code has been generated using the command `swig
-python ccextractorapi.i` and the wrapper could be found at
https://github.com/Diptanshu8/ccextractor/blob/gsoc_work_bento_16_library/linux/ccextractorapi_wrap.c
. Now when I am generating a .so file with this and trying to import the
module in python 2.7, I am getting the following error:





*Traceback (most recent call last): File "<stdin>", line 1, in <module>
File "ccextractorapi.py", line 98, in <module> VERSION =
_ccextractorapi.VERSIONAttributeError: 'module' object has no attribute
'VERSION'*
Tracing back to the ccextractorapi.py file, I am unable to understand how I
am getting this attribute error as this attribute doesn't exist in entire
codebase. Kindly let me know about how to get rid of this error.
I am presently working on Ubuntu 16.04 LTS vagrant box.
Thank you.

Hello,
It seems that I have a line called #define VERSION "0.85" in my codebase
and the corresponding header file is also included in the SWIG interface
file. But still I am getting




*Traceback (most recent call last): File "<stdin>", line 1, in <module>
File "ccextractorapi.py", line 98, in <module> VERSION =
_ccextractorapi.VERSIONAttributeError: 'module' object has no attribute
'VERSION'*
Please let me know where am I going wrong.

Hey there,

I'm guessing it's a linking issue?

Try "ldd <name of .so file>" to verify that you have all of the appropriate
libraries linked. Also, try "nm <name of .so file>" and look for undefined
symbols. I'm hoping this gives you some insight into what sources are
missing.
