About the Reference Implementation
- Problem with the subversion check-out: We are afraid the HTTPS certificate has just expired; however, you can trust it for a few days. In the meantime, here is the command to use:
$ svn co --username guest --password guest --no-auth-cache https://svn.comelec.enst.fr/dpacontest Error validating server certificate for 'https://svn.comelec.enst.fr:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! - The certificate has expired. Certificate information: - Hostname: *.comelec.enst.fr - Valid: from Thu, 23 Sep 2004 12:07:51 GMT until Mon, 22 Sep 2008 12:07:51 GMT - Issuer: CA, Ecole nationale superieure des telecommunications, Paris, Paris, FR - Fingerprint: e7:49:dc:9b:6c:0b:94:2d:ca:b7:e5:89:3a:d9:a3:a7:cd:34:1b:e4 (R)eject or accept (t)emporarily? tand everything goes fine.
- Build process (python setup.py build) failures:
-
We have been reported a platform-dependant bug in the header libpqmodule.h.
The lines 29 & 30 might need to be changed from:
#include <libpq-fe.h> #include <libpq/libpq-fs.h>
to:#include <postgresql/libpq-fe.h> #include <postgresql/libpq/libpq-fs.h>
- Local installation how-to:
-
Use the option --prefix=<DIR> after the command `python setup.py build' to install the package into <DIR>.
For more details about this syntax, you can type `python setup.py build --help'.
After that, you also need to say something like (syntax for sh-compliant shells):
export PYTHONPATH=${PYTHONPATH}:<DIR>/lib.linux-x86_64-2.4for python to be acquainted where to find the module.
