OpenSSL 1.1.0

[glewis64]

Attempting a Linux (RHEL 6.4) build of mailsend v1.20b1 against OpenSSL v1.1.0 with enable-static-engine to embed OpenSSL in mailsend executable. Doing a short google revealed that the OpenSSL method DSO_METHOD_dlfcn was removed in 1.1 and the configure script is reporting "OpenSSL has unsupported dynamic loading".

Is there a work around for this?

Here's the pertinent information from config.log:

The same section from config.log when linking against OpenSSL v1.0.2p:

configure:5754: gcc -o conftest -g -O2 -Wall conftest.c -lresolv -lnsl -L/usr/local/ssl_102p//lib -lssl -lcrypto -ldl >&5 conftest.c: In function 'main': conftest.c:51: warning: implicit declaration of function 'DSO_METHOD_dlfcn' configure:5754: $? = 0 configure:5755: result: yes

configure.in needs to be updated to detect if OpenSSL supports -ldl. However, mailsend should link with OpenSSL fine.

I would agree. However, until it’s fixed I won’t be able to upgrade OpenSSL to 1.1 since we want it embedded in the mailsend executable.

Any idea when that would be available?

You can do it today without any change. This is an example on Ubuntu with OpenSSL 1.1.0i

• Compile OpenSSL statically

  ./config --prefix=/path/ssl110istatic -static
  make
  make test
  sudo make install

• Then compile mailsend

./configure --with-openssl=/path/ssl110istatic
make

Thanks.

Which openssl versions are supported?
