Stavros,
as the error says, the proxy needs a valid ssl library. Apple has removed
OpenSSL from Catalina and from the SDK already in Mojave.
The most simple solution is to disable the QAP/WebSocket proxy with
configure.args="—without-proxy" if you don’t need it (or any other SSL
functionality)
If you intend to use SSL/TLS then you need to install a valid ssl library.
There are several options - you can download the Apple headers and explicitly
link the still-existing system location by using full path to the dylibs in
/usr/lib (it has to be the full path since linker will ignore /usr/lib for -l)
[see PKI package]. Or you can install static OpenSSL build and use it [see
openssl package]. Or you can install local shared version of OpenSSL, just be
careful with that option as you don’t want to conflict with system’s LibreSSL.
Cheers,
Simon
