RE: prefer static linking

["Weaver, John P CIV" <john dot p dot weaver at navy dot mil>]

Following the chain and playing around with the makefile has yielded the
following, judicious use of both -Bdynamic and -Bstatic in front of the
different -l statements does in fact change the behavior of the linker
so that the desired outcome is achieved. Thank you both for your input.

GCC just calls the linker, any preference is the linker's.

For the GNU linker -Bdynamic and -Bstatic allow you to control whether
dynamic or static libraries are used for each lib named with -l 

See 'man ld'

I am not aware of any such option.

If you are using the GNU linker, you can tell it to prefer dynamic
libraries using -Bdynamic and tell it to use only static libraries using
-Bstatic, but I don't know of any option to tell it to prefer static
libraries but use dynamic libraries if they are available.
