我们想要testing这款英特尔引擎的性能，看看它能够提高openssl的性能。
我们按默认步骤编译openssl 1.0.0：
$。/ config; 制造 进行安装
并编译英特尔引擎：
$ make
按照README文件中的说明，
env OPENSSL_ENGINES=`pwd` openssl speed -engine intel-accel -evp rc4 我们有错误：
# env OPENSSL_ENGINES=`pwd` openssl speed -engine intel-accel -evp rc4 invalid engine "intel-accel" 140473186604712:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:185:filename(/home/xxxxx/intel-accel-1.5/libintel-accel.so): /home/xxxxx/intel-accel-1.5/libintel-accel.so: undefined symbol: RSA_sign 140473186604712:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:244: 140473186604712:error:260B6084:engine routines:DYNAMIC_LOAD:dso not found:eng_dyn.c:450: 140473186604712:error:2606A074:engine routines:ENGINE_by_id:no such engine:eng_list.c:417:id=intel-accel 140473186604712:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:185:filename(libintel-accel.so): libintel-accel.so: undefined symbol: RSA_sign 140473186604712:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:244: 140473186604712:error:260B6084:engine routines:DYNAMIC_LOAD:dso not found:eng_dyn.c:450:
有什么build议吗？
