[网络协议]DORIS 编译问题

BE后端 C++编译问题,主要是GCC11在编译DORIS后端时会报各种问题

1 brpc编译问题

1. 1 undefined reference to `COMP_CTX_new'

/usr/bin/ld: t1_enc.c:(.text+0x8a6): undefined reference to `COMP_CTX_new'
/usr/bin/ld: t1_enc.c:(.text+0x986): undefined reference to `COMP_CTX_free'
/usr/bin/ld: t1_enc.c:(.text+0x9a5): undefined reference to `COMP_CTX_new'

/usr/bin/ld: ssl_lib.c:(.text+0x34c1): undefined reference to `COMP_CTX_free'

主要是 -lssl 库顺序在-lcrypto库后面（顺序反了），可以手动修改brpc目录下的CMakeList.txt，修改第

if(WITH_MESALINK)
    list(APPEND DYNAMIC_LIB ${MESALINK_LIB})
else()
    message("dont use mesalink '\n\n\n'  OPENSSL_SSL_LIBRARY ${OPENSSL_SSL_LIBRARY} '\n\n\n' ")
    # list(APPEND DYNAMIC_LIB ${OPENSSL_SSL_LIBRARY})  #将这一行注释掉
endif()


if(CMAKE_SYSTEM_NAME STREQUAL "Linux")
    set(DYNAMIC_LIB ${OPENSSL_SSL_LIBRARY} ${DYNAMIC_LIB} rt)
    set(BRPC_PRIVATE_LIBS "${BRPC_PRIVATE_LIBS} -lrt")

主要是把OPENSSL_SSL_LIBRARY放在?DYNAMIC_LIB的最前面，这样能保证ssl在crypto前面
