caml_atom_table bug still present in ocaml 3.11.0

caml_atom_table bug still present in ocaml 3.11.0

When compiling with ocamlopt from 3.11 on Mac OSX 10.5, I got errors  
about undefined symbols: caml_atom_table and caml_static_data_start,  
and googled out this:

http://caml.inria.fr/pub/ml-archives/caml-list/2005/05/e3905eefb5bca0ae534f009bbd2727b0.en.html

There's also related, if somewhat different, discussion about dylib's at

http://tunes.org/~nef//logs/ocaml/08.02.04

The sollution is still the same, with the only one of the two lines  
remaining from that example in asmrun/startup.c, line 40 in the  
current one:

char * caml_code_area_start, * caml_code_area_end = NULL; /* added the  
initializer */

-- and now things work well.

Under the 2005 thread, the resolution, by John Skaller, was, it should  
go into the bugtracker; did it, and if not, should it now? :)

Cheers,
Alexy

I don't think it dit, and yes you should add it, although it looks  
like a
strange gcc bug.

I was able to compile it fine on the mac (through macports) with these args:

./configure -prefix /opt/local
unset LD_PREBIND LD_PREBIND_ALLOW_OVERLAP && make world.opt

What are you using? And what version of gcc? Mine's set to 4.0.1.

It's not the compilation which is a problem, it's subsequent use of  
ocamlopt.  When trying to link a program which uses C libraries with  
OCaml C stubs, I was getting the undefined symbols until the above fix  
was added, the same as the original email from 2005.

Are you using the latest dev tools (Xcode 3.1.2) ?

Here it compiled on intel without any problems (from the  
distribution), and I used C stubs without any problems.

Best,

Daniel
