Looks like clang had been updated and a new error warning:
core.c:2410:14: error: logical not is only applied to the left hand side of
this comparison
[-Werror,-Wlogical-not-parentheses]
else if (!strcmp(cmd->path, "/") == 0)
^ ~~
core.c:2410:14: note: add parentheses after the '!' to evaluate the comparison
first
else if (!strcmp(cmd->path, "/") == 0)
^
( )
core.c:2410:14: note: add parentheses around left hand side expression to
silence this warning
else if (!strcmp(cmd->path, "/") == 0)
^
( )
