#43815: clisp @2.49: error: unknown argument: '-R/opt/local/lib' -----------------------------+------------------------ Reporter: wanghuan1406@… | Owner: easieste@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.0 Resolution: | Keywords: Port: clisp | -----------------------------+------------------------ Comment (by ryandesign@…): Reading the code in src/port1.0/portconfigure.tcl, it looks like compiler.fallback gets set to "cc" if $xcodeversion is "none" or "". I haven't looked where that variable is set, but indeed the first line of your log is: {{{ :warn:main Xcode does not appear to be installed; most ports will likely fail to build. }}} And that message should have been printed in your terminal as well. This suggests you have not installed Xcode. Please install it, then clean the port and try again. -- Ticket URL: <https://trac.macports.org/ticket/43815#comment:4> MacPorts <http://www.macports.org/> Ports system for OS X
