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.
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
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.
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.
