"Go" iOS lame compile arm64 armv7s armv7 x86_64 i386 instruction set

From the 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 Libmp3lame.a static library used in the previous app also supports the 64-bit simulator (x86_64) and the 64-bit true machine (arm64) instruction set. Need to recompile

Review the following information, follow the steps below, and make some comments and changes

1.http://sourceforge.net/projects/lame/files/lame/3.99/download Lame The latest version of the extract into a folder such as lame, the full path is as follows/users/8wm/desktop/lame

2. Download build script, I use a foreign friend's share here

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

Get lame-build.sh Copy to folder after download/users/8wm/desktop/lame

3. Open the script with BBEdit or another editor and modify it according to the comments

4. Open Terminals,

Input

Cd/users/8wm/desktop/lame

chmod 777 lame-build.sh

sudo-s#

Enter the system password

./lame-build.sh

Start compiling, after compilation is complete. Generate Fat-lame directories and Thin-lame directories, storing static libraries that incorporate all instruction sets, and static libraries for each instruction set.

Copy lame.h and Libmp3lame.a, as requiredfile into project, you can use it normally.
