#42291: llvm-3.4: error: invalid version number in '-mmacosx-version-min=' -------------------------------+------------------------ Reporter: david.w.watson@… | Owner: jeremyhu@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Resolution: | Keywords: Port: llvm-3.4 | -------------------------------+------------------------ Comment (by ryandesign@…): Ah yes. The log shows: {{{ :info:configure checking for sed... /opt/macports/bin/sed }}} What is this? I assume this is GNU sed, but MacPorts gsed port deliberately installs the binary as gsed, not sed; did you manually create a sed symlink to gsed? If so, that's a problem, and would explain the first error shown in the log: {{{ :info:build sed: invalid option -- E }}} `-E` is an option that only works with BSD sed (which is what OS X ships with; GNU sed would require the `-r` option instead). -- Ticket URL: <https://trac.macports.org/ticket/42291#comment:4> MacPorts <http://www.macports.org/> Ports system for OS X
