I am trying to rebuild everything in a development machine with clang
to test for production, and ran into a problem on the buildworld
process. This machine was already rebuilt from source using gcc, here
are the options I have set in make.conf and src.conf. The lines I added
to enable clang, and the steps I took to compile.
Options in /etc/src.conf
WITHOUT_BIND_DNSSEC="YES"
WITHOUT_BIND_LIBS_LWRES="YES"
WITHOUT_BIND_NAMED="YES"
WITHOUT_BIND_UTILS="YES"
WITHOUT_NTP="YES"
WITHOUT_PROFILE="YES"
Options already in /etc/make.conf
WITH_OPENSSL_PORT=yes
WITHOUT_X11=yes
CFLAGS= -O -pipe
PERL_VERSION=5.12.4
Added to /etc/make.conf
.if !defined(USE_GCC)
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
.if !defined(CPP) || ${CPP} == "cpp"
CPP=clang-cpp
.endif
.endif
Did the cleanup process from previous build and currently installed
setup.
chflags -R noschg /usr/obj/usr
rm -rf /usr/obj/usr
cd /usr/src
make cleandir
make cleandir
Then ran make buildworld, it died on libc with the following output:
===> lib/libc (obj,depend,all,install)
clang -O -pipe -I/usr/src/lib/libc/include

Anyone have any idea where I went wrong?
