iOS 移植 openssl

1:到  openssl 官网(https://www.openssl.org/source/)下载源码.注:不用解压.

Tarballs

The table below lists the latest releases for every branch. Old releases can be found at https://www.openssl.org/source/old.

Alternatively, you can find all distribution tarballs in our FTP area, ftp://ftp.openssl.org/source/. A list of FTP mirror sites can be found here.

Development snapshots can be found at ftp://ftp.openssl.org/snapshot/.

We also maintain a clone at GitHub, https://github.com/openssl/openssl.

红色为最新的源码.

2:将build_openssl.sh与openssl源码放在同一目录下.

3:修改内容:

LIB_NAME="openssl-1.0.0r"

将 LIB_NAME修改为下载的源码的文件名,注:不带后缀.

如下载的最新的源码:

LIB_NAME="openssl-1.0.2a"

build_openssl.sh源码:

其中:ARCHS 与 ADKS为一一对应的,如取ARCHS[1],使用的SDK为SDKS[1]

ARCHS=("arm64" "armv7s" "armv7" "i386")
SDKS=("iphoneos" "iphoneos" "iphoneos" "iphoneos")

以上为大牛的脚本.自己做个记录.
