Hi, I was wondering how a autoconf configure script can determine if the kernel is built with a particular option. In this case the code I have can make use of the FreeBSD polling driver, which by default isn't built into a kernel. So I want my configure script to determine if the kernel supports it, if so sets a #define, otherwise doesn't.
In the past I have basically hacked my way though these configure scripts by looking at other examples. One such example I found was for Linux, which does something like this: AC_CACHE_CHECK(for device polling kernel extension, ac_cv_linux_poll_extension, [if grep polling `find_linuxpath include/linux/netdevice.h` >/dev/null 2>&1; then ac_cv_linux_poll_extension=yes else ac_cv_linux_poll_extension=no; fi]) if test $ac_cv_linux_poll_extension = yes; then AC_DEFINE(HAVE_LINUX_POLLING) fi So I simply want to figure out an equalavant check I can do on FreeBSD. thanks 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"
