Hello everybody,
I am having problems with importing a .so shared library I just compiled
following the example giving in the book:
API Design for C++ : www.apibook.com <http://www.apibook.com> (Chapter 11)
I downloaded the Boost library and I compiled it (fullw) into a
subdirectory called /compilation, where I get the /include and /lib
directories. No error during the compilation (Ubuntu 11.10).
Then I downloaded the code from the book examples and I compiled it
without errors and I get the phonebook.so in the same directory as where
I launch python interpreter, but the import in python trigger this error:
ImportError: /home/pablo/phonebook/phonebook.so: undefined symbol:
_ZN5boost6python6detail11init_moduleEPKcPFvvE
what I think is because python does not find the library.
I try to play around with the LD_LIBRARY_PATH variable, ldconfig, I
copied the phonebook.so library into /usr/lib and /usr/local/lib, and
nothing ... I get the same error.
Can anybody explain me what is the problem? thanks a lot in advance,
I think you just need to link your library against the boost_python
library, and make sure that's also somewhere on your dynamic library
path. With gcc, that means adding a "-lboost_python" to the command
line options.
