Hello Bruce, In the build instructions for cups it has: CC=gcc right before the ./configure switch. In the command explanation section it has the following note: CC=gcc: This environment variable ensures that gcc is used, if clang is installed. Remove it, if you prefer to use clang. Using clang almost doubles build time and slightly decreases build disk space. Installed disk space is not appreciably modified. I found that just having CC=gcc was not enough to get this to correctly build, as for some reason the build would still try using clang to, if I have the term correct, linking, ie using clang equivalent of g++ This was not my doing. I am just following what is currently listed in svn for the instructions for both systemd version and for sysv of the book.
