Supporting about compile with lame #54

Closed DickyT closed 8 years ago

DickyT commented 8 years ago

Hi, I was trying to build ffmpeg with --enable-libmp3lame, and I have no idea how to use your lame build script with this ffmpeg build script.

Thank you very much

kewlbear commented 8 years ago

Build lame first. When you use --enable-libXXX, you also need to provide paths to find the lib using -I and -L flags. See X264 in the script for example.

@kewlbear Hi, I just try it, and my CFLAGS is

-arch arm64 -mios-version-min=6.0 -fembed-bitcode -I /Users/KanzakiMirai/XcodeProjects/ffmpeg-objc/FFMP3/lame-ios-build/fat-lame/include

LDFLAGS is

-arch arm64 -mios-version-min=6.0 -fembed-bitcode -L /Users/KanzakiMirai/XcodeProjects/ffmpeg-objc/FFMP3/lame-ios-build/fat-lame/lib

but the compiler still throws an error that ERROR: libmp3lame >= 3.98.3 not found, any idea about this? Thank you very much!

I think it's related to bitcode. You should either remove -fembed-bitcode from this script or add it to lame script.

@kewlbear I got a new issue... While I am running on my simulator, XCode tells me. screen shot 2015-12-03 at 22 17 15

And I also tried disabling bitcode for both lame and ffmpeg, or enabing bitcode for them. Is this the problem that something goes wrong of lame? Thanks!!

Did you link lame to your app?

DickyT commented 8 years ago

Oh I even forget that, now I can run it on my simulator. Thank you very much!!!!
