我使用下面的server.c源代码，生成了以下两个文件：
sinful-host-cert.pem sinful-host.key具体步骤在这里描述：椭圆曲线CA指南 运行程序后出现以下错误：
我使用以下命令进行编译：140722397161136:error:10071065:elliptic curve routines:func(113):reason(101):ec_lib.c:995: 140722397161136:error:0B080075:x509 certificate routines:func(128):reason(117):x509_cmp.c:346:
我认为错误发生在以下代码行：
