Subject: [Caml-list] ocamlmklib fails with code compiled with ocamlopt -c

I found out the next issue when using the native compiler to generate a
dynamic library from C:

  $ ocamlopt -c foo.c
  $ ocamlmklib -o foo foo.o
  /usr/bin/ld: fsync.o: relocation R_X86_64_32 against `.rodata' can not
  be used when making a shared object; recompile with -fPIC
  fsync.o: could not read symbols: Bad value
  collect2: ld returned 1 exit status

But `man ocamlopt' reads:
  -fPIC Generate position-independent machine code. This is the default.

Anyway, I tried specifying manually `-fPIC' and it gave me the same
error.

But with `ocamlc -c' everything works as expected. Is this normal?


Best regards
