I'm using the LAME MP3 encoder to convert the caf formatted file to MP3 format. I downloaded LAME and compile and build all architecture like arm64, armv7, armv7s, armv6, i386, i686, x86_64 successfully. I followed this link to create the libraries.

But I'm trying to create lipo for armv7, arm64, x86_64 which support to my project. But I'm getting fatal error.

Here is the error that I'm getting.

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: build/libmp3lame-arm64.a and build/libmp3lame-armv7.a have the same architectures (x86_64) and can't be in the same fat output file.

I tried the all combination which two architectures can create fat file, except single only creating. I need it for ios 8.1 and above (please mention which architectures should I put in the fat file for iPhone 4s and above)

It looks like something went wrong with your build: libmp3lame-arm64.a, libmp3lame-armv7.a should have been device builds but they seem to have come out as simulator builds.

You can confirm this by running file on them:

file build/libmp3lame-arm64.a build/libmp3lame-armv7.a

I don't know why it happened, nor which of many answers you used in the question you linked to.

Can you give more information on how you configured and built lame?

  • Thanks for the fast reply i already checked indivisual libmp3lame-i386.a with my project its working good. I think i386 is only for simulator!! i'm trying to combine all the library file into one FAT file – svs Apr 18 '15 at 11:29
