I think make buildkernel may build this explicitly rather than depending on the Makefile to do it. > As a side question, why does the Makefile for dev/aic7xxx/aicasm have > -I/usr/include in CFLAGS instead of using some marcos to get to the > source tree I'm actually building from? Because it needs to be built on the host and run on the host. For a cross- build the source tree you are building from might very well be for a different architecture and can't be used to build a binary that will run on the host. -- John Baldwin
