x264 @20140124_1 Build failure vs Xcode v5.1 (5B130a)

[scdeimos+macports.org@…]

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.

Will take a look.
