[pypy-dev] Problems in connecting C++ and python with cppyy

I think I find the problem.
The linux distro I am using is Ubuntu. In the distro, the default
library search path is not controlled by LD_LIBRARY_PATH, but
/etc/ld.so.conf file! Mad.
So, I can load the librarys in /usr/lib with just a name, but have to
give a path to the library in my home.
Apologize for disturbing you, Thank you all!
