Do you really need i386? Are you building it for iOS?

Do you really need i386? Are you building it for iOS?

Actually I used your lame script then I got this. I also added the flags mentioned here. Can you please help me with this. After compiling the lame script, It ends here while compiling ffmpeg-ios

You have to add something like above for lame.

[Vetagiri-Hrushikesh]

I got it. But While building the lame script Iam unable to build for i386 architecture. Iam always ending with this. I guess ffmpeg-ios will build if this issue(while building i386 in lame) is resolved. Can you help me to build the lame properly.

Thank you

[kewlbear]

Did you install command line tools? Can you share config.log?

[Vetagiri-Hrushikesh]

Did you install command line tools? Can you share config.log?

Yeah sure, This is my config.log while building i386 ( for lame script ), Others(arm64 armv7s x86_64 armv7) are running fine.

config.log

[kewlbear]

I can reproduce it. Do you really need i386? If not, I think you'd better remove i386 from both lame and ffmpeg build scripts.

Yeah for now I did removed 1386 and compiled both the libraries and it is working fine. Thank you.
