背景：一個以前可用的項目，然而現在突然無法使用了,編譯時報出上述異常信息

• 出現上述情況的意思很明顯，curl庫找不到openssl對應得鏈接庫：
• 0: 第一步,先看下庫是否真正找不到

ldd /usr/lib/x86_64-linux-gnu/libcurl.so

然後結果顯示：

• 2：就個人而言，庫是能夠鏈接的到,但是可能版本不正確，一種方法是把現在用到的庫給卸載了，暫時不用；
• 3：用了一種比較暴力的方法，將依賴庫加上後綴，讓鏈接庫找不到這個庫，使其默認找系統下的庫；
• 然後就是這種情況了，比較奇怪的是，這兩個庫有什麼區別，不是一樣的嗎，爲什麼其中一個就不行

sbb@uface-gpu-server:~/workspace/ModelServing$ ldd /usr/lib/x86_64-linux-gnu/libcurl.so
        linux-vdso.so.1 =>  (0x00007fff32ab5000)

        libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007faec7253000)

ps: 如果找不到依賴庫，則需要重新安裝新庫；
