The Weirdness With LinuxCNC

I was was eventually able to install version 2.7.14.  I think the ISO was not written correctly first time.  Upgrading to latest version seems too hard. 2.7.14 is ancient history but it works.

I had saved my .emacs, .ddd, and .bashrc files along with all my programs and then restored them.  But lots of things stopped working.  The lisp commands in my .emacs file are not running.  make no longer works.

gcc  - -g -o mkcircle mkcircle.c -lm
gcc: error: -E or -x required when input is from standard input
make: *** [mkcircle] Error 1

Since when did gcc require these flags?

UPDATE: the compile problem was that I accidentally changed CFLAGS=-g to CFLAGS= -g.  That space confused accidentally pretty badly.

My emacs lisp commands are still confused.   The binding to compile command is not using directory from which emacs started.  I am getting close.

And linuxCNC has some setting for maximum Z wrong.
