mpd: error: no type named 'function' in namespace 'std'

Reported by: bnilsson11 Owned by: macports-tickets@…
Priority: Normal Milestone:
Component: ports Version: 2.2.1
Keywords: Cc:
Port: mpd

Description (last modified by ryandesign (Ryan Carsten Schmidt))

mpd does not build:

--->  Building mpd
Error: org.macports.build for port mpd returned: command execution failed
Please see the log file for port mpd for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_audio_mpd/mpd/main.log
In the log file, the first error is:
:info:build In file included from ./src/DatabaseHelpers.hxx:23:
:info:build ./src/DatabaseVisitor.hxx:30:14: error: no type named 'function' in namespace 'std'
:info:build typedef std::function<bool(const Directory &, Error &)> VisitDirectory;

Googling on "no type named 'function' in namespace 'std'" indicates a possible lack of C++11 support.

Replying to bnilsson11@…:

Yes, std::function is a C++11 feature requiring libc++, meaning it will probably only build on Mavericks and higher, if at all.

Confirmed that mpd currently only builds on Mavericks.

Agreed, this requires C++11. r153111
