I looked at the compilation messages, and added the missing parts;
it was not that difficult, after all :-)
The module should now compile, provided you apply the attached patch to
psycopg.
(I suggested the PyDateTime_DELTA_GET_DAYS macros to CPython:
http://bugs.python.org/issue13727 )
The resulting module works a little... at least it yielded a meaningful
error message:
$ ./pypy-c -c "import psycopg2; conn = psycopg2.connect('dbname=test')"
OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
