That is the problem, if polling is enabled there are some symbols which are required which are unavailable if running on a GENERIC kernel. By turning off polling, different #defines are used in the code, removing any calls to the kernel polling functions. So as much as I was like to make this a runtime option, I don't think I can. > > * A configure-time flag to set the 'default' and > > * A runtime option to explicitly specify the current preference when > the program runs. > > This seems a bit more flexible, and does not require an expensive ``go > back to your vendor, and ask for a special build-time option'' cycle to > test different setups when a field installation is done. > Thanks to everyone that has replied. I think I'm just going to make this a configure flag, and if the target system doesn't have a suitable kernel then the software (or kernel) will have to be rebuilt. thanks for your wisdom Andrew _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
