/usr/bin/clang++"  -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -gdwarf-2 -fexceptions -arch x86_64  -DBOOST_ALL_NO_LIB=1 -DBOOST_FILESYSTEM_STATIC_LINK=1 -DBOOST_SYSTEM_STATIC_LINK=1 -DNDEBUG  -I"." -c -o "bin.v2/libs/filesystem/build/darwin-4.2.1/release/address-model-64/architecture-x86/link-static/threading-multi/operations.o" "libs/filesystem/src/operations.cpp"  libs/filesystem/src/operations.cpp:321:8: warning: unused function 'error' [-Wunused-function]   bool error(bool was_error, const error_code& result,        ^

Where is the file ? in the kernel ?
