Hello Jim, I really appreciate your feedback. I did what you mention, and I did it downloading manually the boost library, compiling, etc, etc. Then, I thought, ok, maybe I did something wrong and I downloaded the already compiled boost packages using the synaptic tool in Ubuntu and then I compiled the source code against the Ubuntu boost isntalled packages. The compilation works fine, no errors but I get the same error.
What I do not know is whether the problem is the compilation of the shared library or python. I spent the whole day on this, agrrrrrrrrrrrrrrrrrrrrrrrrr this guy : http://www.mentby.com/vivek-60/ had a similar problem. But, this command: $ nm /usr/local/lib/libboost_python3.so.1.46.1 | c++filt | grep init_module show no symbols for me. Any other idea? 2011/11/25 Jim Bosch <tallji...@gmail.com> > On 11/25/2011 06:54 AM, Edgardo C. wrote: > >> 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.
