 Replying to [comment:26 dsavransky]:
 > Ok.  Confirming that gcc9 fundamentally cannot be built right now
 against 10.15.  However, after restoring command line tools (which install
 SDK 10.14 - does anyone understand what Apple is doing here?) John's
 method of building everything from source works fine.  Thanks very much
 John and Joshua.

 One should consider the opportunity to **repair** some apparent slip of
 Apple XCode **by a workaround** such as the simple provision of an
 appropriate ''symbolic link'' by help of the command-line (CLI) as
 described below:


 {{{
 $ cd
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/

 $ sudo ln -s MacOSX.sdk MacOX10.14.sdk
 }}}


 Hope this helps.
