There is a strange error building clang with this use case: cd /usr/src make -j10 makeworld which produces this error output: ===> lib/clang/libclang (all) error: unable to rename temporary 'Sema/SemaTemplate-12ad7e30.o.tmp' to output file 'Sema/SemaTemplate.o': 'No such file or directory' 1 error generated. --- Sema/SemaTemplate.o --- *** [Sema/SemaTemplate.o] Error code 1 make[6]: stopped in /usr/src/lib/clang/libclang .ERROR_TARGET='Sema/SemaTemplate.o' .ERROR_META_FILE='/usr/obj/usr/src/amd64.amd64/lib/clang/libclang/Sema_SemaTemplate.o.meta' .MAKE.LEVEL='6' MAKEFILE='' .MAKE.MODE='meta missing-filemon=yes missing-meta=yes silent=yes' _ERROR_CMD='c++ -target x86_64-unknown-freebsd12.0 --sysroot=/usr/obj/usr/src/amd64.amd64/tmp -B/usr/obj/usr/src/amd64.amd64/tmp/usr/bin -O2 -pipe -DNO_MALLOC_EXTRAS -I/usr/obj/usr/src/amd64.amd64/lib/clang/libclang -I/usr/obj/usr/src/amd64.amd64/lib/clang/libllvm -I/usr/src/contrib/llvm/tools/clang/lib/Basic -I/usr/src/contrib/llvm/tools/clang/lib/Driver -I/usr/src/contrib/llvm/tools/clang/include -DCLANG_ENABLE_ARCMT -DCLANG_ENABLE_STATIC_ANALYZER -I/usr/src/lib/clang/include -I/usr/src/contrib/llvm/include -DLLVM_BUILD_GLOBAL_ISEL -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -DLLVM_DEFAULT_TARGET_TRIPLE=\"x86_64-unknown-freebsd12.0\" -DLLVM_HOST_TRIPLE=\"x86_64-unknown-freebsd12.0\" -DDEFAULT_SYSROOT=\"\" -DLLVM_TARGET_ENABLE_X86 -DLLVM_NATIVE_ASMPARSER=LLVMInitializeX86AsmParser -DLLVM_NATIVE_ASMPRINTER=LLVMInitializeX86AsmPrinter -DLLVM_NATIVE_DISASSEMBLER=LLVMInitializeX86Disassembler -DLLVM_NATIVE_TARGET=LLVMInitializeX86Target -DLLVM_NATIVE_TARGETINFO=LLVMInitializeX86Tar getInfo -DLLVM_NATIVE_TARGETMC=LLVMInitializeX86TargetMC -ffunction-sections -fdata-sections -Qunused-arguments -DNO_MALLOC_EXTRAS -std=c++11 -fno-exceptions -fno-rtti -stdlib=libc++ -Wno-c++11-extensions -c /usr/src/contrib/llvm/tools/clang/lib/Sema/SemaTemplate.cpp -o Sema/SemaTemplate.o;' .CURDIR='/usr/src/lib/clang/libclang' .MAKE='make' .OBJDIR='/usr/obj/usr/src/amd64.amd64/lib/clang/libclang' .TARGETS='all' DESTDIR='/usr/obj/usr/src/amd64.amd64/tmp' LD_LIBRARY_PATH='' MACHINE='amd64' MACHINE_ARCH='amd64' MAKEOBJDIRPREFIX='' MAKESYSPATH='/usr/src/share/mk' MAKE_VERSION='20180512' PATH='/usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin:/usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/bin:/usr/obj/usr/src/amd64.amd64/tmp/legacy/bin:/usr/obj/usr/src/amd64.amd64/tmp/usr/sbin:/usr/obj/usr/src/amd64.amd64/tmp/usr/bin:/sbin:/bin:/usr/sbin:/usr/bin' SRCTOP='/usr/src' OBJTOP='/usr/obj/usr/src/amd64.amd64' .MAKE.MAKEFILES='/usr/src/share/mk/sys.mk /usr/src/share/mk/local.sys.env.mk /usr/src/share/mk/src.sys.env.mk /etc/src-env.conf /usr/src/share/mk/bsd.mkopt.mk /usr/src/share/mk/src.sys.obj.mk /usr/src/share/mk/auto.obj.mk /usr/src/share/mk/bsd.suffixes.mk /etc/make.conf /usr/src/share/mk/local.sys.mk /usr/src/share/mk/src.sys.mk /etc/src.conf /usr/src/lib/clang/libclang/Makefile /usr/src/share/mk/src.opts.mk /usr/src/share/mk/bsd.own.mk /usr/src/share/mk/bsd.opts.mk /usr/src/share/mk/bsd.cpu.mk /usr/src/share/mk/bsd.compiler.mk /usr/src/share/mk/bsd.linker.mk /usr/src/lib/clang/clang.pre.mk /usr/src/lib/clang/llvm.pre.mk /usr/src/lib/clang/clang.build.mk /usr/src/lib/clang/llvm.build.mk /usr/src/share/mk/bsd.lib.mk /usr/src/share/mk/bsd.init.mk /usr/src/share/mk/local.init.mk /usr/src/share/mk/src.init.mk /usr/src/lib/clang/libclang/../Makefile.inc /usr/src/share/mk/bsd.libnames.mk /usr/src/share/mk/src.libnames.mk /usr/src/share/mk/bsd.symver.mk /usr/src/share/mk/bsd.nls.mk /usr/src /share/mk/bsd.files.mk /usr/src/share/mk/bsd.incs.mk /usr/src/share/mk/bsd.confs.mk /usr/src/share/mk/bsd.links.mk /usr/src/share/mk/bsd.dep.mk /usr/src/share/mk/bsd.clang-analyze.mk /usr/src/share/mk/bsd.obj.mk /usr/src/share/mk/bsd.subdir.mk /usr/src/share/mk/bsd.sys.mk' .PATH='. /usr/src/lib/clang/libclang /usr/src/contrib/llvm/tools/clang/lib' 1 error However, if I do this cd /usr/src/lib/clang/libclang make -j10 depend all it succeeds.
