[Caml-list] Where is __ctype_b defined?

[Caml-list] Where is __ctype_b defined?

[Tomek Grzejszczyk]

Hi,
	I'am trying to compile mldonkey, but the compilation fails during linking 
with the following message:

ocamlopt.opt -inline 10 -linkall  -o mlnet       unix.cmxa str.cmxa 
-cclib -lz -ccopt "-pthread"   -I build    build/cdk.cmxa 
build/common.cmxa    build/client.cmxa    build/core.cmxa 
build/driver.cmxa    src/daemon/common/commonMain.cmx

/usr/lib/ocaml/libstr.a(regex.o)(.text+0x1288): In function `regex_compile':
: undefined reference to `__ctype_b'

Maybe I've some mising files in my ocaml distribution or broken 
dependencies between my ocaml packets, but to check it I need to know 
where is __ctype_b symbol defined.

Thanks for help,
Tomek Grzejszczyk

Definitely not in OCaml; most probably in libc (the C library).

My guess is that you're using OCaml binaries that were compiled
against a given version of the C library, and using them with a
different, incompatible C library.  The solution is to recompile OCaml
from sources.
