I am using ccache. My /etc/make.conf contains the following: -------------------------8<------------------------- CPUTYPE?=native CFLAGS=-O3 -pipe COPTFLAGS=-O -fno-strict-aliasing -pipe MAKE_JOBS_NUMBER=4 CC=clang CXX=clang++ CPP=clang-cpp NO_WERROR= WERROR= MAKE_SHELL?=sh INSTALL=install -C # from ccache-howto-freebsd.txt .if (!empty(.CURDIR:M/usr/src*) || !empty(.CURDIR:M/usr/obj*)) .if !defined(NOCCACHE) CC:=${CC:C,^clang,/usr/local/libexec/ccache/world/clang,1} CXX:=${CXX:C,^clang\+\+,/usr/local/libexec/ccache/world/clang++,1} CCACHE_DIR:=/usr/sysccache .endif .endif .if ${CC:T} == "clang" CFLAGS+= -Qunused-arguments .endif -------------------------8<------------------------- The output from make is too long to post inline so you can find the relevant portion here: http://sprunge.us/BfWJ I suspect that the error is caused by -march=native, my CPU is an Intel Core i5. I'll admit that I did modify my make.conf right before building. It already *did* contain the CC/CXX/CPP lines for clang but the ccache portion was slightly different. It used to contain the literal contents of ccache-howto-freebsd.txt: CC:=${CC:C,^cc,/usr/local/libexec/ccache/world/cc,1} CXX:=${CXX:C,^c\+\+,/usr/local/libexec/ccache/world/c++,1} Today I re-read that howto and it states: "You can replace cc and c++ with the compilers of your choice. (remember that only GCC and Clang can build world and kernel)" So I updated those two lines and replaced cc/c++ with clang/clang++. I didn't get the make errors before. So I moved those two lines back, did rm -rf /usr/obj/* and started another make buildworld which is still running. I always thought that specifying 'CPUTYPE?=' in the Makefile is the right way to prevent issues like this. So did I do something wrong, or is this some kind of ccache issue, or is this a legitimate bug? Please shed some light on this, thanks.
