Hi,
As of r212979, you should now be able to build world and kernel on i386
and amd64 with clang, without any additional patches!
To do so, make sure you have updated your installed world to at least
r212904 (which has the most recently imported clang/llvm snapshot), and
put the following in /etc/src.conf:
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
Just tried it. World has been builded without any problems, but stge
kernel module failed to compile:
