ffmpeg was built successfully with --use-clang. 2336-10.7

[jankkhvej]

I have successfully built ffmpeg with --use-clang on the Mac OS 10.7.2 and Xcode Version 4.2.1. Thus filing a "bug" as requested by brew with this info:

2336-10.7

[pwoolcoc]

This also worked for me. brew upgrade ffmpeg --use-clang

[Abai]

Also works on Mac OS 10.6.8 Xcode Version 4.2 (4C199). 2336-10.6

[keithws]

Also worked for me on Mac OS X 10.7.2 with Xcode 4.2.1.

brew install ffmpeg does not work. brew install ffmpeg --use-gcc does not work (as there is no GCC) brew install ffmpeg --use-clang does work.

[adamv]

MacPorts has code in several ports that explicitly switches the compiler to clang if llvm-gcc-42 is detected (on the assumption that the Xcode w/ llvm-gcc-42 also provides clang, which it does).

We need to start doing something like that in these cases too.

I have the same system setup as keithws, and same findings as levinalex

[towynlin]

Hm. With OS X 10.7.2 and Xcode _4.1_ ffmpeg fails to build with all three of LLVM (build 2335), Clang (2.1-163.7.1), and GCC (4.2 build 5666). Downloading Xcode 4.2.1 now...

edit: not strictly true, macports conflicts, keep reading below...

@towynlin

FFmpeg definitely builds under XCode 4.1 if the --use-gcc flag is passed. You could be experiencing some other issue.

[towynlin]

@Sharpie

Thanks for the reality check. I'm gradually migrating from macports; in fact, this ffmpeg install was a choice to switch to homebrew rather than upgrade the port. In any case, --use-clang worked (still with Xcode 4.1) only after I completely moved macports out of the way. Default LLVM failed, but I'm guessing gcc would work too now that macports is out of the way.

As an intermediate step, I tried default, clang, and gcc with the system pkg-config (rather than the macports one) by moving macports to the end of my PATH, which still failed in all three cases. According to brew doctor, any of the following config scripts could have been the problem:

cppunit-config curl-config freetype-config gdlib-config icu-config libpng-config libpng14-config ncurses5-config ncursesw5-config nspr-config pcap-config pcre-config php-config pkg-config python-config python2.7-config rarian-sk-config scrollkeeper-config sdl-config xml2-config xslt-config

ffmpeg 0.8.7 successfully built on XCode 4.2.1, OS X 10.7.2 using --use-clang
did not work without the --use-clang flag

[gerrit]

Mac OSX 10.7.2, fresh install of Xcode 4.2, brew-installed gcc-4.6 symlinked to /usr/local/bin/gcc, fails with brew install ffmpeg, brew install ffmpeg --use-gcc and brew install ffmpeg --use-clang

[dkam]

This worked for me also: brew upgrade ffmpeg --use-clang

Result: 2335-10.7

[jcf]

Worked here with brew install ffmpeg --use-clang.

Result: 2336-10.7

[huwge]

Worked with --use-clang on 10.7.2

Result: 2335-10.7

[casallas]

Also worked here with --use-clang on OS X 10.6.8

Result: 2336-10.6

[tetherit]

Works here with --use-clang too on 10.7.2

[franciscoj]

+1 for --use-clang

[RSully]

verified, works with --use-clang today

2336-10.7

brew install ffmpeg --use-clang works now @ bb99486

[dickoff]

Failed with brew upgrade ffmpeg --use-clang on 10.7.2 and XCode 4.2.1
brew doctor doesn't come up with any errors.

Appears to be an upstream issue? The configure fails on ERROR: libx264 version must be >= 0.118. Looking in my /usr/local/lib I have
libx264.116.dylib libx264.dylib

[mistydemeo]

@mdickoff You need to brew upgrade x264. The most recent version in Homebrew is the version that ffmpeg is looking for.

[dickoff]

@mistydemeo , hmm, I had tried this, however, brew upgrade x264 wasn't doing the trick. I needed to do a brew uninstall x264 and then brew install x264 for it to upgrade the libs.

[reco]

brew upgrade ffmpeg --use-clang dint work for me 10.7.2 Xcode 4.2.1

[mistydemeo]

@reco Please open a new issue and gist the complete failure log.

[exiva]

@reco look up higher in the output, I think you may have run into the x264 issue @mdickoff pointed out. Just tried it with --use-clang and it worked perfectly.

[jredville]

Success: 2335-10.7

@mdickoff Thanks for the suggestion. --use-clang was failing for me, but once I did brew uninstall x264 it worked.

[dannyarcher]

--use-clang

worked

[olistik]

brew install ffmpeg --use-clang

worked for me.

[nilcolor]

2336-10.7

--use-clang option helps.

Huh. There is no libmp3lame formula at this time.

Just did a brew update at 201201061718 US/Central.

[jacknagel]

libmp3lame is part of the lame package.

[fguillen]

Doesn't work for me:

brew install ffmpeg
brew install ffmpeg --use-clang 
brew install ffmpeg --use-gcc

Neither with the trick:

brew remove --force x264
brew install x264

[mistydemeo]

@fguillen Can you please gist your brew --config and brew doctor output?

[fguillen]

@mistydemeo sure!:

• https://gist.github.com/1653583#gistcomment-77739

[mistydemeo]

It looks like you have Macports installed. Having both Macports and Homebrew active at the same time can cause problems. Try removing Macports from your path, then install ffmpeg again.

If that doesn't work, uninstall and reinstall pkg-config with Homebrew.

[egermano]

Hi, i got a same error here.

I post a question here: http://stackoverflow.com/questions/8965639/ffmpeg-install-fail-osx-10-7-2

Anyone can help me?

I really need instal this to test codes in sites...

Plzzz

[mistydemeo]

@egermano Did you read the message brew doctor gave you? Did you try following its advice?

[Sharpie]

@egermano

Looks like the error has to do with libmp3lame:

ERROR: libmp3lame >= 3.98.3 not found

This is also one of the unbrewed dylibs flagged by brew doctor.

[fguillen]

@mistydemeo: thanks for the suggestion, but even brew is an awesome tool I still depend on MacPorts for installing several tools that are not available in brew.

I tried to uninstall MacPorts just to make the test your asked me, but it ended with several errors and I was worry to compromise my system and in consequence my work productivity.

[egermano]

Hi everyone,

I read with more attention my brew doctor and fix all thing they that warn, but i could not install with success.

I found the article where the author build a script to install the ffmpeg and all dependency and thats works.

http://hunterford.me/compiling-ffmpeg-on-mac-os-x/

Pity that the brew did not work well in my environment.

Thank for all
