I am no socket expert, and any debugging advice would help. Your code has been wrong for 10 years, it should be if(bind(s, (struct sockaddr *)&sa, sizeof(sa)) < 0) { You were passing 0 as namelen parameter (since sizeof(sa) > 0). Not sure why this would work with gcc 3 and not with 4 though. Jonas _______________________________________________ Do not post admin requests to the list. They will be ignored.

I did this, built the project (deployment), copied the libsasl2.2.dylib and libsql.so files to the appropriate place and they work as expected without any bad side affects. I've also modified the postfix-144 project to use mysql, pcre and netinfo. Now if I could get CyrusIMAP to work with mysql, virtual users e-mail (without local accounts) would be a breeze and a reality. This email sent to site_archiver(a)lists.apple.com

The volfs filesystem does something like this, I think. Is it part of Darwin? Cheers, Chris _______________________________________________ Do not post admin requests to the list.

All access to the data starts at the top and proceeds downward throughout the levels of the hierarchy. Most all operating systems use hierarchical file systems to store data and programs. For example, in Windows, the top of the hierarchy is the drive letter, such as C: or D:, followed by folders and subfolders. darwin support UFS and HFS This email sent to site_archiver(a)lists.apple.com
