[Frama-c-discuss] Compilation of Beryllium 20090901 without dynlink

The configure is right: /usr/lib/ocaml/dynlink.cmxa does not exist for 
your platform. So dynlink does not properly work in native (i.e. with 
ocamlopt) but I have understood that you have no native compiler: that's ok.

I don't understand your issue: in all cases, Dynlink (dynlink.cma) is 
available and linked against the bytecode (frama-c.byte). If I follow 
your instructions, the compilation succeeds for building the bytecode 
binary but fails for building the native binary. This failure is quite 
normal (as Pascal already answers). I have a local patch on my machine 
in order to be able to compile with ocamlopt >= 3.11 without 
dynlink.cmxa, but is it really necessary? I'm not sure...

So have you any reproducible issue with the bytecode (e.g. a dynamic 
plug-in like Jessie does not work) or have you any wanted feature wish 
for supporting a non-yet-available platform?
