编译ios版openssl(2013/01/28)

2015/9/24 更新：

昨天试图在Xcode7上编译最新版本openssl，发现已经有了更简单的方案：

https://github.com/x2on/OpenSSL-for-iPhone

下载下来直接跑 build-libssl.sh 即可。全自动，连下载openssl都帮你搞定……

强烈推荐使用这种方法来做

-----------------------------------------

1. 首先要有个openssl的源码包 http://www.openssl.org/source/

   P.S. 如果你想知道自己现有项目中用到的openssl是哪个版本的，可以看include里面的opensslv.h这个文件，其中有诸如

   

#define OPENSSL_VERSION_TEXT "OpenSSL 1.0.0e 6 Sep 2011"

这样的行，就知道版本了。

2. 可能需要对源码做一些修改已利于编译

crypto/ui/ui_openssl.c

将

static volatile sig_atomic_t intr_signal;

修改为：

static volatile int intr_signal;

3. 将本文附件（待上传，内容见文末） OpenSSL_ios_Build.zip中的shell批处理openssl_make_macOS.sh和三个补丁文件patch_mf_i386.diff/patch_mf_armv6.diff/patch_mf_armv7.diff 放置在openssl目录下，给予openssl_make_macOS.sh足够的权限来运行：

   在终端下：


chmod 777 openssl_make_macOS.sh
./openssl_make_macOS.sh

会在openssl的同级目录生成ssllibs目录，其中ssllibs/libcrypto.a ssllibs/libssl.a 是最终编译完并合并完各框架版本的lib文件
