Simply take a look at ports that required /src or /sys to compile, eg. lsof or fusefs-kmod: lsof has: FREEBSD_SYS?= /usr/src/sys fusefs-kmod has: SRC_BASE?= /usr/src So neither of them use a predefined var. > Second, I need to invoke make includes (and a few other things), with > some slightly non-standard args. is there a stylied way to do this? > I'd like to avoid extracting everything into myport/work/FreeBSD :) Not quite sure on *when* you want to run make includes and if you want to run it for the port or for /usr/src? You could override the "pre-build:" target with stuff necessary pre build :) > Without solving these problems, the notion that we can use a ports > compiler to build FreeBSD becomes less viable... > > Comments?
