 Priority:  Normal                   |  Milestone:
Component:  ports                    |    Version:  2.2.1
 Keywords:  mavericks                |       Port:  x264
-------------------------------------+--------------------------------
 x264 @20140124_1
 OS X v10.9.2
 Xcode v5.1 (5B130a)
 Apple LLVM version 5.1 (clang-503.0.38)


 Install x264 fails with the following error in config.log:
 --
 clang: error: unknown argument: '-falign-loops=16' [-Wunused-command-line-
 argument-hard-error-in-future]
 clang: note: this will be a hard error (cannot be downgraded to a warning)
 in the future
 --

 It appears that the x264/Portfile:post-path method is not correctly
 detecting clang, so it is failing to remove the "-falgin-loops=16"
 configure option.

 The following workaround is not currently usable (downloading
 llvm-3.3-3.3_1.darwin_13.x86_64.tbz2 times out):
 --
 sudo port clean x264
 sudo port install apple-gcc42
 sudo port install x264 configure.compiler=apple-gcc-4.2
 --

 The following hack allows install to complete:
 --
 mkdir ~/ports/multimedia/x264
 cd ~/ports/multimedia/x264
 cp
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/multimedia/x264/Portfile
 .
 echo "#Fix error:" >> Portfile
 echo "#clang: error: unknown argument: '-falign-loops=16' [-Wunused-
 command-line-argument-hard-error-in-future]" >> Portfile
 echo "#clang: note: this will be a hard error (cannot be downgraded to a
 warning) in the future" >> Portfile
 echo "configure.cflags-append -Qunused-arguments" >> Portfile
 echo "configure.cppflags-append -Qunused-arguments" >> Portfile
 cd ~/ports
 portindex
 sudo port install x264

 HTH,
 Anthony.
