Summary

0001956: Name clashes

Description

Hello Lars and caml-bugs,

There is a name clash between the libcrypto and libcamlrun on the symbol
create_string. This prevents from linking statically an OCaml program that
uses the ocurl library (bindings to the libcurl, which uses libcrypto), and
I guess that horrible things may happen at runtime with dynamic linking.

Similar issues have been raised recently on the caml-list (concerning
the libsamba, libperl, and graphviz libraries).

Any plan to address these issues?

OCaml is no more faulty than these libraries, but this is not a reason not
to fix the problem :-)

A natural solution would be to prefix all the common names like
create_string or get_string. To keep the compatibility with existing C
code that uses Caml C headers, there could be two versions of these
headers (the compatibility header would #DEFINE create_string as
ocaml_create_string and so on).
