Add -static to the ld command line to produce a staticly linked binary:
this forbids ld(1) from doing any dynamic linking. Otherwise ld will
default to dynamic linking, but fall back to linking staticly against
libraries where there isn't a dynamic shared object available.
Actually, there are about 4 different linker flags you could use that
mean 'produce a staticly linked binary.' They don't have any different
effect; the reason they exist is for historic compatibility with
versions of ld(1) from many different sources.
It's also an all-or-nothing option. If you wanted to use static linkage
for one particular library out of all the libraries used by your
program, then you'ld need a very different command line. But that, as
they say, is left as an exercise for the student.
Cheers,
Matthew
