I've never seen that. Actually, installworld, not installkernel. >> Without the 2nd hunk, the lint program would call "cc", which does not exist (ie., there is no /usr/bin/cc, but there is a ${CC}). > > This sounds like a bug. Well, now, with a CC environment variable, the hunk is no longer required for me. But then again, the lint program calls "cc" if there is no CC environment variable, such as when CC is set only in make.conf. According to <https://wiki.freebsd.org/ExternalToolchain>: > To use XCC, you must not set any of the variables that can be overridden by X* variables in /etc/make.conf or /etc/src.conf as Makefile.inc1 will be unable to change them. Why? In my case, CC should always be /path/to/clang (however, CFLAGS should contain --sysroot=/usr/obj/<...>, when appropriate).Received on Wed Jun 05 2013 - 20:16:44 UTC
