I replied to this to another person and neglected to cc: hackers.
So, let me explain.
I was compiling a hacked copy of slattach.c. I noticed the binary
was huge and figured out that it was being linked statically.
Being of a curious mind, I decided to investigate and found the
place in bsd.prog.mk where it was tested to control whether or not
shared libs are used.
What bothered me at that point was why the original binary was linked
to use shared libs and the /usr/src/sbin/slattach directory's Makefile
caused slattach to be statically linked when I made it? If the binary that
came with the dist was dynamically linked, why was my new compile static?
I then went looking for where NOSHARED was set. I figured it had
to be in /usr/src/sbin/slattach's Makefile. No dice. I even looked at
/usr/src and usr/src/sbin Makefiles. No dice.
That is what prompted the question. Maybe it's because the distribution
was trimmed by picking and choosing what binaries to make dynamic to save
space in the distribution and the source tree just makes them all static
to simplify things?
If so, my question remains.. where the heck is it set to YES or TRUE?
Just curious..
