#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@…): Turns out dtrace isn't actually used to trace anything, but to generate a header file from rts/RtsProbes.d to allow better tracing of Haskell programs. However, my call of dtrace does actually not fail: {{{ "/usr/sbin/dtrace" -Iincludes -Iincludes/dist -Iincludes/dist- derivedconstants/header -Iincludes/dist-ghcconstants/header -Irts -Irts/dist/build -C -x cpppath=/usr/bin/clang -h -o rts/dist/build/RtsProbes.h -s rts/RtsProbes.d }}} Did you try running this command manually? What happens if you run the command itself under `dtruss(1)`? Does Console.app contain any useful information on the problem? -- Ticket URL: <https://trac.macports.org/ticket/48612#comment:5> MacPorts <https://www.macports.org/> Ports system for OS X
