I tried your suggestions but it leads to the same error message (using g++
-shared foo.cpp -o foo.so -I /usr/include/python2.6 -lpython2.6
-lboost_python).
Could there be something wrong with the installation?
In the meantime I tried it on an OSX machine, installed boost 1.45 by hand
(using bjam --with-python). The error is exactly the same.
I suppose the code should be fine as its from the docs. Am I missing an
important step?
