(OK) 在CentOS7—编译OpenSSL 静态库—for—Android

参考： https://wiki.openssl.org/index.php/Android

下载makedepend.zip , 从http://llg.cubic.org/docs/vc7.html下载。 解压编译，然后 cp makedepend /bin/
下载Setenv-android.sh , wget https://wiki.openssl.org/images/7/70/Setenv-android.sh

[root@localhost openssl-1.0.1p]# gedit Setenv-android.sh        //关键设置如下：
