1.下载GCC编译工具 Xcode-Preferences-tools-Command Line Tools

2.下载最新的2.4.11下来

3.终端进入 freetype目录，然后输入命令

$ ./configure --prefix=/usr/local/iphone --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2  CFLAGS="-arch armv7 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=3.2 -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include/libxml2 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk" CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv7 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -miphoneos-version-min=3.2"$ make clean;make$ cp objs/.libs/libfreetype.a libfreetype-arm7.a

$ ./configure --prefix=/usr/local/iphone --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2  CFLAGS="-arch armv7 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=3.2 -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include/libxml2 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk" CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv7 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -miphoneos-version-min=3.2"$ make clean;make$ cp objs/.libs/libfreetype.a libfreetype-arm7.a

三个步骤编译完成之后 得到了.a文件。之后的如何计算宽高以及匹配字体正在研究中。

4.如果报错，就是SDK 不行

第一步骤改成

 ./configure --prefix=/usr/local/iphone --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc CFLAGS="-arch armv7 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=5.1 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/includebxml2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk" CPP=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/binvm-cpp-4.2 AR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=5.1"

即可。
