When I use the command gcc teste.c -lssl -o teste: Error: ubuntu@omap:~/arquivos$ gcc rsa.c -lssl -o teste /tmp/ccyvrO2i.o: In function `main': rsa.c:(.text+0x8): undefined reference to `BN_new' rsa.c:(.text+0xe): undefined reference to `BN_new' rsa.c:(.text+0x14): undefined reference to `BN_new' rsa.c:(.text+0x1a): undefined reference to `BN_new' rsa.c:(.text+0x20): undefined reference to `BN_new' /tmp/ccyvrO2i.o:rsa.c:(.text+0x26): more undefined references to `BN_new' follow /tmp/ccyvrO2i.o: In function `main': rsa.c:(.text+0x5c): undefined reference to `BN_set_word' rsa.c:(.text+0x66): undefined reference to `BN_set_word' rsa.c:(.text+0x70): undefined reference to `BN_set_word' rsa.c:(.text+0x98): undefined reference to `BN_generate_prime' rsa.c:(.text+0xba): undefined reference to `BN_generate_prime' rsa.c:(.text+0xbe): undefined reference to `BN_CTX_new' rsa.c:(.text+0xca): undefined reference to `BN_mul' rsa.c:(.text+0xd4): undefined reference to `BN_sub' rsa.c:(.text+0xe2): undefined reference to `BN_bn2dec' rsa.c:(.text+0xf6): undefined reference to `BN_sub' rsa.c:(.text+0xfa): undefined reference to `BN_CTX_new' rsa.c:(.text+0x106): undefined reference to `BN_mul' rsa.c:(.text+0x114): undefined reference to `BN_bn2dec' rsa.c:(.text+0x11c): undefined reference to `BN_bn2dec' rsa.c:(.text+0x124): undefined reference to `BN_bn2dec' rsa.c:(.text+0x140): undefined reference to `BN_rand' rsa.c:(.text+0x1b8): undefined reference to `BN_mul' rsa.c:(.text+0x1c6): undefined reference to `BN_bn2dec' rsa.c:(.text+0x1de): undefined reference to `BN_bn2dec' rsa.c:(.text+0x1f6): undefined reference to `BN_bn2dec' rsa.c:(.text+0x204): undefined reference to `BN_CTX_new' rsa.c:(.text+0x216): undefined reference to `BN_div' rsa.c:(.text+0x224): undefined reference to `BN_bn2dec' rsa.c:(.text+0x236): undefined reference to `BN_cmp' rsa.c:(.text+0x24a): undefined reference to `BN_bn2dec' rsa.c:(.text+0x252): undefined reference to `BN_bn2dec' rsa.c:(.text+0x25a): undefined reference to `BN_bn2dec' rsa.c:(.text+0x262): undefined reference to `BN_bn2dec' rsa.c:(.text+0x26a): undefined reference to `BN_bn2dec' collect2: ld returned 1 exit status
Another attempt: ubuntu@omap:~/arquivos$ gcc rsa.c -Wl, -lssl, -lcrypto -o teste /usr/bin/ld: cannot find : No such file or directory /usr/bin/ld: cannot find -lssl, collect2: ld returned 1 exit status Any idea? I haven't found the libssl.so in my directory /usr/lib.
