#48942: Compiler error trying to install Astropy -----------------------------+-------------------------------- Reporter: shj.wallstrom@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Keywords: | Port: -----------------------------+-------------------------------- I've been trying to install py27-astropy for days now, to no avail, despite frantic googling. I get the following error: "Error: org.macports.build for port py27-astropy returned: command execution failed Please see the log file for port py27-astropy for details: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports .org_release_tarballs_ports_python_py-astropy/py27-astropy/main.log" Checking the log file tells me (eventually): ":info:build Compiler specified by CC environment variable :info:build (/usr/bin/llvm-gcc-4.2:i686-apple-darwin11 -llvm-gcc-4.2 (GCC) 4.2.1 (Based on App$ :info:build Copyright (C) 2007 Free Software Foundation, Inc. :info:build This is free software; see the source for copying conditions.

I did not appear to have this, so I installed it via macports and now have "clang-3.4 @3.4.2_9+analyzer+arm_runtime (active)" but the error persists. So how do I tell macports to use a different compiler in this case? -- Ticket URL: <https://trac.macports.org/ticket/48942> MacPorts <https://www.macports.org/> Ports system for OS X
