Has anyone been able to successfully compile the kernel using GCC as against CLANG the default compiler on most later versions of FreeBSD? I was able to successfully buildworld. After which I reboot and now /usr/bin/cc points to GCC as requested. However kernel fails to link Here is my src.conf: COPTFLAGS+= -O0 -pipe -Wno-attributes -Wno-redundant-decls WERROR="-Wno-error" WITHOUT_CLANG="yes" WITHOUT_CLANG_IS_CC="yes" WITHOUT_CLANG_BOOTSTRAP="yes" WITH_GCC_BOOTSTRAP="yes" WITH_GCC="yes" WITH_GNUCXX="yes" WITHOUT_JAIL="yes" WITHOUT_WIRELESS="yes" WITHOUT_WIRELESS_SUPPORT="yes" WITHOUT_WPA_SUPPLICANT_EAPOL="yes" WITHOUT_CDDL="yes" It fails here: >>> stage 3.1: building everything -------------------------------------------------------------- cd /usr/obj/usr/src/sys/AIJAZ-DEBUG; COMPILER_VERSION=40201 COMPILER_FEATURES= COMPILER_TYPE=gcc COMPILER_FREEBSD_VERSION=1200001 MAKEOBJDIRPREFIX=/usr/obj MACHINE_ARCH=amd64 MACHINE=amd64 CPUTYPE= CC="cc -isystem /usr/obj/usr/src/tmp/usr/include -L/usr/obj/usr/src/tmp/usr/lib -B/usr/obj/usr/src/tmp/usr/lib --sysroot=/usr/obj/usr/src/tmp -B/usr/obj/usr/src/tmp/usr/bin" CXX="c++ -isystem /usr/obj/usr/src/tmp/usr/include -L/usr/obj/usr/src/tmp/usr/lib -B/usr/obj/usr/src/tmp/usr/lib --sysroot=/usr/obj/usr/src/tmp -B/usr/obj/usr/src/tmp/usr/bin" CPP="cpp -isystem /usr/obj/usr/src/tmp/usr/include -L/usr/obj/usr/src/tmp/usr/lib -B/usr/obj/usr/src/tmp/usr/lib --sysroot=/usr/obj/usr/src/tmp -B/usr/obj/usr/src/tmp/usr/bin" AS="as" AR="ar" LD="ld" LLVM_LINK="" NM=nm OBJCOPY="objcopy" RANLIB=ranlib STRINGS= SIZE="size" INSTALL="sh /usr/src/tools/install.sh" PATH=/usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj/usr/src/tmp/legacy/bin:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/bin:/sbin:/bin:/usr/sbin:/usr/bin make -D KERNFAST -m /usr/src/share/mk KERNEL=kernel all -DNO_MODULES_OBJ linking kernel.full ck_array.o: In function `ck_cc_popcount': /usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: undefined reference to `__popcountdi2' ck_barrier_centralized.o: In function `ck_cc_popcount': /usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: undefined reference to `__popcountdi2' ck_barrier_combining.o: In function `ck_cc_popcount': /usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: undefined reference to `__popcountdi2' ck_barrier_dissemination.o: In function `ck_cc_popcount': /usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: undefined reference to `__popcountdi2' ck_barrier_mcs.o: In function `ck_cc_popcount': /usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: undefined reference to `__popcountdi2' ck_barrier_tournament.o:/usr/src/sys/contrib/ck/include/gcc/ck_cc.h:139: more undefined references to `__popcountdi2' follow *** Error code 1 Stop. make[2]: stopped in /usr/obj/usr/src/sys/AIJAZ-DEBUG *** Error code 1 Stop. make[1]: stopped in /usr/src *** Error code 1 Stop. make: stopped in /usr/src Is there something else I am missing?
