Has anyone been able to get src/ciphertest to run (and actually
list algorithms/modes) with the current version (2.4.10) of the
security/libmcrypt port? I've cooked up a horrendous hack (see
attached patch) that makes it work for me, but I'm wondering how
it could ever work the way it stands for anyone using any OS.
From lib/mcrypt_extras.c:
_version = lt_dlsym(_handle, "_mcrypt_algorithm_version");
Basically when listing the available modules it looks for this
symbol to see if it is a valid module. The problem is this though
from modules/algorithms/xtea.c:
#define _mcrypt_algorithm_version xtea_LTX__mcrypt_algorithm_version
Unless I'm missing the totally obvious the first simple above will
never be in the resultant object file because it is being defined
as something else. Sure enough if I "remove" these defines (see
attached patch) everything works as expected.
Unless someone has a better way of fixing this I'll commit this
shortly so I won't have to keep installing version 2.2.7 of this
port and hacking up the mod_php4 port everytime I want mcrypt
support that works.
Anyone care to explain how this could ever work, for anyone?
Thanks.
-steve
