/usr/bin/ld: /tmp/ccs04b2O.o: in function `decrypt_replay(std::vector<unsigned char, std::allocator<unsigned char> >&, unsigned char const*)':
decrypt.cpp:(.text+0x66): undefined reference to `BF_set_key'
/usr/bin/ld: decrypt.cpp:(.text+0x16c): undefined reference to `BF_ecb_encrypt'
collect2: error: ld returned 1 exit status
使用 sudo apt-get install libssl-dev 進行了安裝, 使用了 g++ -o a.out -lssl decrypt.cpp 進行編譯,仍然報錯.
請教各位大佬這是什么原因?

現在的報錯成這個了........是因為庫沒有裝嗎?還是缺了啥....?
$g++ -o a.out -lcrypto -lssl trial.cpp

順序不要錯 ...-lssl -lcrypto
或者用 -Wl,--start-group -Wl,--end-group 把所有的 .o .a .so 放一個組里去...
