• problem compiling ffmpeg for iFrameExtractor

  11 septembre 2012, par Robin Rye

  I'm trying to compile the ffmpeg by using the make and build files in iFrameExtractor example. firstly i tried to follow the readme file on the github, which only says to run the ./build_universal in ffmpeg folder. it did not work

  i then tried to follow the info in INSTALL without success. i then tried doing the stuff in INSTALL followed by the ./build_universal which didn't work. All the *.a files that are imported to the project exists until the end of the build sequence. when the lipo commands in build_universal are run, which i guess concat the .a files for the different architectures(?). anyhow these leave the following errors :

  lipo: specifed architecture type (armv6) for file (armv6/libavcodec.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
  
  lipo: specifed architecture type (armv6) for file (armv6/libavdevice.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
  
  lipo: specifed architecture type (armv6) for file (armv6/libavformat.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
  
  lipo: specifed architecture type (armv6) for file (armv6/libavutil.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
  
  lipo: specifed architecture type (armv6) for file (armv6/libswscale.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))

  i can get the project to compile for simulator if i only use ./build_armv7 but if i run the universal the .a files are removed in the end. and only using doesn't work to build for iphone 4 .

• building MobileVLC -> armc7 + ffmpeg issue

  28 septembre 2012, par Shamil

  I'm trying to build MobileVLC on OS X Lion, against iOS SDK 5.0. So far, no dice.

  Followed the given instructions, however, build stops and fails here :
  [info] Building contrib for iOS in '/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-builddir-ios-i686-apple-darwin10

  Current log :
  ./buildMobileVLC.sh -s
  [info] Preparing build dirs
  [info] Building
  [info] Building vlc
  [info] Building libvlc for the iOS
  [info] Using i386 with SDK version 4.2
  [info] Building contrib for iOS in '/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-builddir-ios-i686-apple-darwin10'

  The error is given as follows :

  make[1]: *** [.ffmpeg] Error 1
  
  make: *** [using-src] Error 2

  /ImportedSources/vlc/contrib-builddir-ios-arm-apple-darwin10/build-src/ffmpeg/config.log tells me :

  ld: warning: directory not found for option 'L/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-ios-arm-apple-darwin10/lib'
  
  ld: warning: directory not found for option '-L/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-ios-arm-apple-darwin10/lib'
  
  **ld: in /usr/lib/system/libcache.dylib, missing required architecture armv7 in file for architecture armv7**
  
  collect2: ld returned 1 exit status
  
  C compiler test failed.

  I've bolded the one which I think is causing it to fail. Now - how do I fix THIS error ?
