[R-SIG-Mac] Fail to install Rserve 1.8-6

[Simon Urbanek]

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
