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

[Stavros Panidis]

Hi all,

Configuration is as follows

MacOS  Catalina 10.15.5
R version 4.0.1

I try 

install.packages('Rserve',,'http://www.rforge.net/‘)

And then attempt to install from sources. At the end I get the following message

ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [forward] Error 1
make: *** [all] Error 2
ERROR: compilation failed for package ‘Rserve’
* removing ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rserve’

The downloaded source packages are in
	‘/private/var/folders/lr/dz6qc47x3zg_2d_dzd5jtq5m0000gn/T/RtmpeSL5uH/downloaded_packages’
Warning message:
In install.packages("Rserve", , "http://www.rforge.net/") :
  installation of package ‘Rserve’ had non-zero exit status

Any help on this?

Many thanks in advance

Stavros
