Thanks for your reply. I tried '-static' earlier (see posts last week) &
the linker couldn't find static libraries for LibGL, libGLU & libGLw.
I also tried gcc5 to link (see earlier posts today) & it seemed to still
dynamically link libstdc++, even w/ the '-static-libstdc++' argument.
Your suggestion to use the explicit linker arguments -Bstatic &
-Bdynamic is the next thing to try, however they will require a bit more
mods to my Makefile & I thought my attempts using various
'-static-lib<whatever>' should/would work, based on my read of the man
pages.
