[Switch] iOS lame compilation arm64 armv7s armv7 x86_64 i386 instruction set, arm64armv7s

Original to http://blog.csdn.net/vieri_ch/article/details/40650467

Recently upgraded the system to Mac OS X 10.10 and updated XCode6.1 and iOS 8.1.

The libmp 3lame. a static library used by the app also supports 64-bit simulators (x86_64) and 64-bit real machine (arm64) instruction sets. Need to be re-compiled

After reading the following documents, follow these steps and make some comments and changes.

1. http://sourceforge.net/projects/lame/files/lame/3.99/ to download the latest version of lame decompress to a folder such as lame, the full path is as follows/Users/8wm/Desktop/lame

2. Download the build script, which is shared by a foreign friend.

Https://github.com/kewlbear/lame-ios-build

Download and get the lame-build.sh copy to the folder/Users/8wm/Desktop/lame

3. Use bbedit or another editor to open the script and modify it according to the comment.

4. Enable Terminals,

Input

Cd/Users/8wm/Desktop/lame

Chmod 777 lame-build.sh

Sudo-s #

Enter the system password

/Lame-build.sh

Start compilation. Generate the fat-lame directory and the thin-lame directory, respectively store the static libraries that merge all instruction sets and the static libraries of each instruction set.

Copy the lame. h and libmp 3lame. a files to the project as required.

You can use the command line to view the instruction sets supported by another database.

Lipo-info libmp 3lame.

Ubuntures in the fat file: libmp 3lame. a are: armv7 armv7s i386 x86_64 arm64

The following is a build script. Note the yellow words and comments.
