ffmpeg install failed (Lion GM, clean install so no SL upgrade, Xcode 4.2 beta2 for Lion) #6278

Trying the new xcode 4.1 DP7 also released yesterday, maybe the 4.2 xcode is the issue.


Using vanilla gcc-4.2 from /Developer/usr/bin/gcc-4.2 solves the problem. Just compiled ffmpeg on Lion with success.


Strange, using gcc-4.2 doesn't work for me.


the same problem here, 4.2 doesn't help.


I just realised I have it up and running on Build 11A49a (prior to GM). Today I am going to install the update and will let you know if it's a GM specific issue or not.


I'm also having this same problem on the GM.


same here. :(

Looks like this error was fixed in FFmpeg/FFmpeg@f04d434 on the FFmpeg tree. Now I get this failure:


brew install --use-clang --HEAD ffmpeg

works for me on Lion


I can confirm d--j's command works.


confirmed as well, nice catch
