My guess is that your source tree is inconsistently updated. This error can only occur when SIGNAL_POLLING_UNSUPPORTED is defined to 1 in MainLoop.cpp, and that can only occur if your copy of lib/clang/include/lldb/Host/Config.h is either out of date, corrupt, or empty. Can you check whether the following lines exist in your copy of lib/clang/include/lldb/Host/Config.h: #define HAVE_SYS_EVENT_H 1 #define HAVE_PPOLL 1 If not, it is best to delete your source tree and do a fresh checkout. > Trying "env WITHOUT_CLANG=YES WITH_GCC=YES make buildworld" also fails, > however in /usr/src/lib/libc/tests/ssp (as make says): > > cc -O2 -pipe -fstack-protector-all -Wstack-protector -fsanitize=bounds -g > -std=gnu99 -fstack-protector-strong -Wsystem-headers -Wall -Wno-format-y2k > -Wno-uninitialized -Wno-pointer-sign -Wno-empty-body -Wno-string-plus-int > -Wno-unused-const-variable -Wno-tautological-compare -Wno-unused-value > -Wno-parentheses-equality -Wno-unused-function -Wno-enum-conversion > -Wno-unused-local-typedef -Wno-address-of-packed-member -Wno-switch > -Wno-switch-enum -Wno-knr-promoted-parameter -Qunused-arguments -o > h_raw.full h_raw.o > /usr/obj/usr/src/tmp/usr/bin/ld: > /usr/obj/usr/src/tmp/usr/lib/clang/5.0.1/lib/freebsd/libclang_rt.ubsan_standalone-x86_64.a: > No such file: No such file or directory > cc: error: linker command failed with exit code 1 (use -v to see invocation) > > Again - as I did not see similar issues on the mailing list, I wonder what's > going on here.

In this case, I think you would also need WITHOUT_CLANG_BOOTSTRAP. Or alternatively, build using WITHOUT_TESTS. -Dimitry
