Openssl-1.0.0c编译报错 libcrypto.so: undefined reference to `ENGINE_load_aep'的问题

来源：互联网发布：王铁崖知乎编辑：程序博客网时间：2024/06/05 08:05

环境：centos5.5 gcc

1.下载解压Openssl-1.0.0c
2.配置,执行：./config

3.查看Makefile的OPTIONS选项，这里我配置成编译动态库，如果是编译静态库，应该就不会报这个错。

OPTIONS=enable-shared -Wa,--noexecstack no-ec_nistp_64_gcc_128 no-gmp no-jpake no-krb5 no-md2 no-rc5 no-rfc3779 no-sctp no-store no-zlib no-zlib-dynamic no-static-engine

4.找到 CFLAG 变量，在变量的最后加上：-DOPENSSL_NO_STATIC_ENGINE 保存退出，再编译即可。

报错信息：

../libcrypto.so: undefined reference to `ENGINE_load_atalla'
../libcrypto.so: undefined reference to `ENGINE_load_4758cca'
../libcrypto.so: undefined reference to `ENGINE_load_gost'
../libcrypto.so: undefined reference to `ENGINE_load_padlock'
../libcrypto.so: undefined reference to `ENGINE_load_nuron'
../libcrypto.so: undefined reference to `ENGINE_load_sureware'
../libcrypto.so: undefined reference to `ENGINE_load_chil'
../libcrypto.so: undefined reference to `ENGINE_load_cswift'
../libcrypto.so: undefined reference to `ENGINE_load_aep'
../libcrypto.so: undefined reference to `ENGINE_load_ubsec'
collect2: ld 返回 1
make[2]: *** [link_app.gnu] 错误 1

其他配置参考：

LIBS= libcrypto.a libssl.a
SHARED_CRYPTO=libcrypto$(SHLIB_EXT)
SHARED_SSL=libssl$(SHLIB_EXT)
SHARED_LIBS=$(SHARED_CRYPTO) $(SHARED_SSL)
SHARED_LIBS_LINK_EXTS=.so.$(SHLIB_MAJOR) .so

声明的头文件：

openssl-1.0.1c/include/openssl/engine.h 约 335行
