The problem seems to relate to the Mysql parts of vpopmail because it's returning with "undefined reference" and all the errors are pointing to Mysql. I used the same configure as you gave me Ken as the one where you didn't have any trouble, mainly because it seems if you point to files in different locations from default it can stuff things up :) ./configure --without-authuserdb --without-authpam \ --without-authpwd --without-authshadow --without-authldap \ --with-authvchkpw --enable-workarounds-for-imap-client-bugs The errors returned are: collect2: ld returned 1 exit status make[1]: *** [authvchkpw] Error 1 make[1]: Leaving directory '/usr/src/courier-imap-1.3.8.1/authlib' make: *** [all-recursive] Error 1 There were lots & lots of references to mysql i.e.: undefined reference to 'mysql_query' undefined reference to 'mysql_store_result' undefined reference to 'mysql_free_result' undefined reference to 'mysql_fetch_row' etc. etc............. Anyone know what configure item I need to correct the problem, or how else to fix it? I don't know enough about programming to change any of the files, unless I am just copying what someone else writes, and with directions on where to put it :) Any and all help will be appreciated Thanks in advance Regards Roger PS Sorry for sending another email to the list so soon Ken but I can't fix this one easily :) BTW everyone, Ken is the greatest and deserves many thanks from me, which I would like to do publicly :)
