Linking failure with OpenSSL 1.1

[shastah]

Trying to compile with OpenSSL 1.1 leads to:

checking openssl/err.h presence... yes

checking openssl/ssl.h usability... yes
checking openssl/ssl.h presence... yes

make[1]: *** [Makefile:507: relay] Error 1

Adding -lcrypto to LIBSSL in Makefile resolves the issue (but configure should handle that for me).

agreed, thanks for the issue

Can you perhaps send me the relevant snippet from config.log around the OPENSSL_add_all_algorithms_noconf check? I'd like to see what the actual problem/error is.

Hi, I have the same problem. Here is the relevant snippet from config.log.

I tweaked conftest.c as below:

#include <openssl/crypto.h>
#include <openssl/evp.h>

int
main ()
{
return OPENSSL_add_all_algorithms_noconf ();
  ;
  return 0;
}

With the above modification, it compiles successfully.

# gcc -o conftest -g -O2 -fdebug-prefix-map=/build/carbon-c-relay-Ik8vNO/carbon-c-relay-3.3=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -Wl,-Bsymbolic-functions -Wl,-z,relro conftest.c -lcrypto
# echo $?

By the way, I created a PPA deb package of carbon-c-relay for Ubuntu 18.04 LTS. https://launchpad.net/~hnakamur/+archive/ubuntu/carbon-c-relay

[grobian]

ok, thanks, so we should check another symbol :)
