Hello, I am having some problems to link my program with the SSL library libssl.a and libcrypto.a. I have a small program called sslexample.c that just opens a simple SSL connection. However, if I compile the program to use the shared libraries libssl.so and libcrypto.so then everything works fine.
The following links and compiles correctly: ========================================================= gcc -lssl -lcrypto sslexample.c -o sslexample or gcc /usr/lib/libssl.so /usr/lib/libcrypto.so sslexample.c -o sslexample ========================================================= However, if I try to compile statically I get problems. There are many undefined symbols when we reach the link stage: ========================================================= gcc /usr/lib/libssl.a /usr/lib/libcrypto.a sslexample.c -o sslexample /tmp/ccAiuJ1H.o(.text+0xe7): In function `main': : undefined reference to `ERR_load_BIO_strings' /tmp/ccAiuJ1H.o(.text+0xec): In function `main': : undefined reference to `SSL_load_error_strings' /tmp/ccAiuJ1H.o(.text+0xf1): In function `main': : undefined reference to `OPENSSL_add_all_algorithms_noconf' /tmp/ccAiuJ1H.o(.text+0xfc): In function `main': : undefined reference to `SSLv23_client_method' /tmp/ccAiuJ1H.o(.text+0x105): In function `main': : undefined reference to `SSL_CTX_new' /tmp/ccAiuJ1H.o(.text+0x11d): In function `main': : undefined reference to `SSL_CTX_load_verify_locations' /tmp/ccAiuJ1H.o(.text+0x148): In function `main': : undefined reference to `ERR_print_errors_fp' /tmp/ccAiuJ1H.o(.text+0x156): In function `main': : undefined reference to `SSL_CTX_free' /tmp/ccAiuJ1H.o(.text+0x17b): In function `main': : undefined reference to `SSL_new' /tmp/ccAiuJ1H.o(.text+0x18e): In function `main': : undefined reference to `BIO_new_socket' /tmp/ccAiuJ1H.o(.text+0x1a5): In function `main': : undefined reference to `SSL_set_bio' /tmp/ccAiuJ1H.o(.text+0x1b3): In function `main': : undefined reference to `SSL_connect' /tmp/ccAiuJ1H.o(.text+0x1d5): In function `main': : undefined reference to `SSL_get_verify_result' /tmp/ccAiuJ1H.o(.text+0x1ea): In function `main': : undefined reference to `SSL_get_verify_result' /tmp/ccAiuJ1H.o(.text+0x20c): In function `main': : undefined reference to `BIO_free_all' /tmp/ccAiuJ1H.o(.text+0x21a): In function `main': : undefined reference to `SSL_CTX_free' /tmp/ccAiuJ1H.o(.text+0x249): In function `main': : undefined reference to `SSL_write' /tmp/ccAiuJ1H.o(.text+0x263): In function `main': : undefined reference to `SSL_read' /tmp/ccAiuJ1H.o(.text+0x2a1): In function `main': : undefined reference to `BIO_free_all' /tmp/ccAiuJ1H.o(.text+0x2af): In function `main': : undefined reference to `SSL_CTX_free' collect2: ld returned 1 exit status ========================================================= I am using a linux machine running fedora core 3. The version of openssl that comes with fedora core 3 is openssl-0.9.7a. But I have also downloaded and installed the latest openssl-0.9.7g and I get the same problem when I try to link statically. My gcc version is 3.4.3 ======================================================================== gcc -v Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.3/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux Thread model: posix gcc version 3.4.3 20050227 (Red Hat 3.4.3-22.fc3) ======================================================================== There must probably be something wrong with the way I link programs. Which means I do not know how to link statically :) ... does anyone know the problem that I am having ?
