[Octave-bug-tracker] [bug #49712] Cannot unload oct file from a SWIG generated wrapper

[anonymous]

Follow-up Comment #2, bug #49712 (project octave):

Hi Mike,

Thanks a lot for the fast feedback. Interesting results; most likely is seems
bound to my setup.

I attached a simple test case:
- swig_test.hpp / swig_test.cpp are the files to be wrapped
- swig_test.i is the swig interface file
- wrapper.cpp is the wrapper generated by swig (3.0.10) through the command:
swig -c++ -octave -o wrapper.cpp swig_test.i
- To generate the oct file I ran:
mkoctfile -std=c++11 --no-gnu-unique -o swig_test.oct swig_test.cpp
wrapper.cpp

Then, in Octave, it followed these steps:
> swig_test
2 swig_ref objects ('cvar' and 'swig_test') appeared in the workspace.
> test
> test
> test
Printed 0, then 1, then 2.
> clear all
Then the workspace was cleared.
> test
And here I got a 3 in the output while I expected the command not to be found.
It shows that the library was still loaded.

This is fully repeatable on my setup.

The only way I could get it working is if I create a symlink 'test.oct'
pointing to 'swig_test.oct'. Then calling 'test' from  Octave and performing a
'clear all' works as expected. But I don't see how I can extend this if C++
classes are involved.


Am I missing something obvious? If you need more details, please feel free to
ask.
