            Bug ID: 18709
           Summary: Compilation fails on Darwin 11.4.2 in darwin-nat.c
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: jkordani at lsa2 dot com
  Target Milestone: ---

Created attachment 8451
  --> https://sourceware.org/bugzilla/attachment.cgi?id=8451&action=edit
changes per compiler warnings.

cc1: warnings being treated as errors
darwin-nat.c: In function ‘darwin_ptrace’:
darwin-nat.c:259: warning: format ‘%x’ expects type ‘unsigned int’, but
argument 5 has type ‘caddr_t’
darwin-nat.c: In function ‘darwin_resume’:
darwin-nat.c:839: warning: format ‘%x’ expects type ‘unsigned int’, but
argument 4 has type ‘long int’
darwin-nat.c: In function ‘cancel_breakpoint’:
darwin-nat.c:1065: warning: format ‘%x’ expects type ‘unsigned int’, but
argument 3 has type ‘long int’
darwin-nat.c: In function ‘_initialize_darwin_inferior’:
darwin-nat.c:2174: warning: format ‘%lx’ expects type ‘long unsigned int’, but
argument 3 has type ‘mach_port_t’

patch attached, although I don't know if the change for line 259 and 2174 are
the right approach.

ptrace may be done without sudo, it depends on the ptrace_scope kernel
