Hi,=A0

I'd like to pa=
ckage up some OCaml code (along with C bindings) as a shared library. Howev=
er, I'm encountering the following linker error:





/u=
sr/bin/ld: /usr/lib/ocaml/libasmrun.a(startup.o): relocation R_X86_64_32 ag=
ainst `.rodata.str1.1' can not be used when making a shared object; rec=
ompile with -fPIC






/usr/lib/ocaml/libasmr=
un.a: could not read symbols: Bad value

Do I have to recompile OCaml=
 with -fPIC to put the runtime inside a shared library?=A0
