I don't care that *you* have nothing to do with src/sys, but libc (and other base libs and utilities) do care. >> Your libc is being built against an old set of includes, so >> it is up to you how to want to modify your build >> environment >> to account for this. >> > > I install FreeBSD includes from /usr/src/include and libs from > /usr/src/lib.

So that "Your libc is > being built against an old set of includes" is just pure nonsense, and > stupid statement made without knowing what people are doing. It's not nonsense, it is the truth. "old set of includes" includes /usr/include and everything under it (/usr/include/sys, /usr/include/machine, etc), with sys and machine notably being part of src/sys. The files in /usr/src/include are not the complete set of includes, and a 'make install' from there does not install all the includes. Depending on what you are doing and what you require, you need to at least setup an include directory that includes the files from /usr/src/include, /usr/src/sys/sys (as <sys/*.h> and /usr/src/sys/<arch>/include (as <machine/*.h>). You should do a 'ls -1F /usr/include | grep /' and see just what you are missing by only relying on /usr/src/include. -- DE
