#48612: ghc build failed on dtrace -------------------------+---------------------------- Reporter: J.Gilbey@… | Owner: kitchen.andy@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Resolution: | Keywords: Port: ghc | -------------------------+---------------------------- Comment (by cal@…): I'm surprised the build actually uses dtrace, especially since it's useless without root privileges on OS X, and we do builds as unprivileged user. Is your dtrace a standard installation? What's the output of `ls -lash /usr/bin/dtrace`? And here's to random guessing: Did you by any chance put a SUID bit on dtrace? MacPorts' builds are sandboxed, and SUID binaries cannot be run in sandboxed environments. They fail with this exact error message. Console.app would also contain a message about this. You can temporarily disable the use of sandboxing by putting `enable_sandbox no` into `macports.conf`, but please don't keep it as the default. -- Ticket URL: <https://trac.macports.org/ticket/48612#comment:3> MacPorts <https://www.macports.org/> Ports system for OS X
