- build libfreetype:
下载 freetype：http://www.freetype.org/，解压
运行
./configure --prefix=/usr/local/iphone --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 CFLAGS="-pipe

-Wl,-dead_strip -miphoneos-version-min=2.0"
如果有任何错误检查config.log文件
configure完成然后运行
make
- 下载相应代码，同样的方法来build libjpg，libpng，libproj。
- build libtiff
下载libtiff source，http://www.libtiff.org/
