Psycopg2: Fails to build 2.8.4

[frankcash]

Hello,

I tried to install psycopg2==2.8.4 on OSX with Python 3.7.4 in a virtualenv.

Error log:

    ld: library not found for -lssl
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'clang' failed with exit status 1

Switched to psycopg2==2.8.3 and it installed like a charm.

I saw there is recently a change, so figured this report might be helpful.

I also had openssl installed through brew

(venv) ➜  openssl version
OpenSSL 1.0.2t  10 Sep 2019
(venv) ➜  which openssl
/usr/local/opt/openssl/bin/openssl

Had the same issue, even with 2.8.3 on Mac OS Catalina. Could fix it with installing openssl via brew install openssl

After that exporting Flags via:

export LDFLAGS="-L/usr/local/opt/openssl/lib" export CPPFLAGS="-I/usr/local/opt/openssl/include"

Installation was successfull.

Finding the libraries in non-standard locations is not something we can do automatically (unless you can in a way I'm not aware, for which a patch is welcome).
