Hi, I have some problems in building py4s on Ubuntu Lucid Lynx LTS.
This is what I've done:

1. installed Cython with the command >>>sudo easy_install cython
2. copied the source code of 4store in the same folder where the folder py4s is
3. build py4s with the command >>>python install.py build

The building process fails and return this error:

cythoning _py4s.pyx to _py4s.c

Error converting Pyrex file to C:
------------------------------------------------------------
...
cdef class _Cursor:
    cdef py4s.fsp_link *_link
    cdef py4s.fs_query_state *_qs
    cdef py4s.fs_query *_qr
    cdef char *_query
    cdef bool _transaction
        ^
------------------------------------------------------------

'bool' is not a type identifier

Could you help me out?

No funciona la última versión

Here is what I get when trying to compile py4s :

Need adding a line "from cpython cimport bool" in _py4s.pyx.
See http://wiki.cython.org/FAQ#HowdoIdeclareanobjectoftypebool.3F

First had size_t issue mentioned here: http://www.rufuspollock.org/2010/02/08/howto-install-4store/

But then had:

It seems like some of the includes have been renamed (4s-datatypes.h, 4s-hash.h) and a couple of method signatures changed.
