(I have seen some documentation that they are available in the imminently available FreeBSD 7 line.) Thus, the issue is almost certainly not with the gcc compiler but rather the configuration of the NTP distribution: it shouldn't have chosen to use timer_create but rather setitimer. In looking at the NTP distribution, it's not clear to me why this should fail. Are you sure that you started with a clean distribution tree? I recently compiled and installed ntp-4.2.4p4 on FreeBSD 6.3-RELEASE using the FreeBSD ports system (and the default gcc 3.4.6), and it compiled and now operates without any obvious errors. I note, however, that the FreeBSD people have provided two small patch files -- both associated with configuring the stock NTP distribution for use on the various release versions of FreeBSD. I just tried configuring that version of ntp using the supplied configuration tools (i.e., w/o the FreeBSD patch files), and it properly detected the lack of timer_create (i.e., it wrote "/* #undef HAVE_TIMER_CREATE */" in the top level config.h). It also compiled successfully using gcc 4.3.0 20071221. So, I really would suspect stale configuration files on your system. I'm not sure of the level of your programming experience as this "compiler error" should have been relatively simple to diagnose given access to the NTP source, the grep command, and the FreeBSD man pages; yet you appear to be running a version of FreeBSD from the source repository (rather than a released system). In any case, I would suggest strongly that you consider using the FreeBSD ports system as it drastically reduces the stress associated with maintaining third-party system software. You could start by reading the FreeBSD handbook and/or the "ports" man page, both of which are part of the standard FreeBSD installation. - dmw -- . Douglas Wells . Connection Technologies . .
