UnsatisfiedLinkError: dlopen failed: library "libcrypto.so.1.0.0" not found

动态调用openssl库时报错：

原因

如果换成.a就没有问题。这是由于没有加载openssl的库。

解决方法

需要改为如下调用

System.loadLibrary("crypto");

System.loadLibrary("ssl");

System.loadLibrary("native-lib");

参考：https://github.com/frankmorgner/openpace/issues/27

如果仍然报错可以尝试如下方法

安装rpl

brew install rpl
rpl -R -e .so.1.0.0 "_1_0_0.so" ./libcrypto.so

调用的时候改为调用crypto_1_0_0，如：System.loadLibrary("crypto_1_0_0");
