Which version of libvpx are you trying to install? I don’t see this problem on Mavericks with libvpx @1.3.0_1.

[posita (Matt Bogosian)]

Oops! I meant to include that in the title. Yes, it's @1.3.0_1. It started showing up with that package version (as far as I know).

I just solved similar problem. Some intrinsics functions like _mm256_set1_epi16 were missing until I install the latest Command Line Tools (for OS X Lion, in my case) from Apple Developer Downloads.

clang -v ::

Before:

Apple clang version 3.1 (tags/Apple/clang-318.0.61) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

After:

Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

I hope this will help…

Replying to neverlunch@…:

I was having the same issue with libvpx, and your suggestion helped. I am on OS X Lion 10.7.5 with Xcode 4.6.3, and installing Command Line Tools (OS X Lion) for Xcode - April 2013 resolved this issue for me.

FWIW, my before/after version info is identical to yours.

Thank you!

Replying to neverlunch@…:

Thanks for your feedback. I am also on OS X Lion 10.7.5, with Xcode 4.6.3 and Apple clang version 3.1. Instead of updating Command Line Tools, the following commands did the trick for me. It didn't configured and compiled libvpx, but it seemed to download a binary.

sudo port clean --all libvpx
sudo port install clang-3.4
sudo port install libvpx configure.compiler=macports-clang-3.4

After doing this, in order to verify if it was overkilling, I removed clang and it's leaves (viz. llvm-3.4), and libvpx. Then, a normal installation worked without the "configure.compiler=macports-clang-3.4":

sudo port uninstall clang-3.4
sudo port uninstall llvm-3.4
sudo port -f uninstall libvpx
sudo port clean --all libvpx
sudo port install libvpx

So, maybe it was just a matter of doing a forced remove, cleaning and reinstalling... but it is strange that I think it was the first thing I tried when this bug showed up, and it didn't worked. Did anyone fix the port to work with the old Command Line Tools?

[neverlunch@…]

IMHO, nobody won't be able to fix anything as failures are due to missing intrinsics functions (aka "functions inside compiler"). Nevermind and upgrade your CLT.

[alessanderbotti@…]

The issue just reappeared on an update of ffmpeg and it was not just a matter of doing a forced remove, cleaning and reinstalling. In the last time, the command

sudo port install libvpx configure.compiler=macports-clang-3.4

just downloaded and installed a binary, and I didn't noticed that I needed the +universal variant, for which there is no binary. So, I really had to install clang and compile libvpx +universal with macports-clang-3.4:

sudo port clean --all libvpx
sudo port install clang-3.4
sudo port install libvpx +universal configure.compiler=macports-clang-3.4

I don't want to update CLT because the lab I study provided me a Mac but not a personal Apple ID, what is required to download CLT as an Apple Developer. If I can, I'll avoid asking my lab for an Apple ID...

Fixed in r122008 by blacklisting old clangs that have this problem. Guessing somewhat on the versions of Xcode clang to blacklist; that part may need further refinement.
