[Caml-list] static linking

Hi,

I'm trying to build a rather big system written in Ocaml, using ocamlbuild.
I managed to set all the needed flags nicely, so that the resulted binaries
can run on any Unix machine, independent on their Ocaml distribution.
However, on certain machines I have problems with the compatibility between
the C libraries. Hence, I tried using "-ccopt -static"  for the -lflags and
-cflags, respectively, in order to produce the desired statically linked
binaries while building the project. Unfortunately, this attempt leads to
the following error:

"/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `cos' with pointer equality in
`/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libm.a(s_sin.o)'
can not be used when making an executable; recompile with -fPIE and relink
with -pie"

Does this mean I need to recompile the gcc libraries using -pie? Or does it
mean I am using the wrong method to build the standalone executable? Any
recommendation to modify the building process (i would prefer to use
ocambuild)?

Your answer is much appreciated,
Andreea
