Build error w/ Findlib on Mandrake 10.1

Build error w/ Findlib on Mandrake 10.1

[Matt Gushee]

Hello, all--

A user of my Bantam file manager has reported a very strange compilation 
error:

   ocamlfind ocamlopt -package "unix str labltk" -c common.ml
   ocamlfind ocamlopt -package "unix str labltk" -c util.ml
   ocamlfind ocamlopt -package "unix str labltk" -c config.ml
   ocamlfind ocamlopt -package "unix str labltk" -c images.ml
   ocamlfind ocamlopt -package "unix str labltk" -c bantam.ml
   ocamlfind ocamlopt -package "unix str labltk" -linkpkg -o bantam.bin \
     common.cmx util.cmx config.cmx images.cmx bantam.cmx
   Cannot find file /usr/lib/ocaml//labltk/labltk.so.cmxa
   make: *** [opt] Error 2

This user is not very familiar with OCaml; he is using the Mandrake 10.1 
RPM(s).

Although I suspect there was an error on the part of whoever packaged 
OCaml (or Findlib) for Mandrake, perhaps there is an error on my part. 
Just in case, I have included my Makefiles below.

Does anyone have an idea what's wrong? I'd appreciate any suggestions.

Does the file /usr/lib/ocaml/labltk/labltk.so.cmxa exists ? Or the  
file /usr/lib/ocaml//labltk/labltk.cmxa without ".so" ?

In my ocaml version, I don't have any .so in caml library names. Try  
to create a symlink from labltk.so.cmxa to labltk.cmxa

Good luck

That's a good question. Based on the error messages, I presumed not, but 
I didn't specifically ask. But if that file did exist, what on earth 
would it be? As far as I know, there is no such thing as an '.so.cmxa' 
file, nor any reason for it to exist.

Another good question; I'll try to find out.

Hmm ... thank you, but that's a kludge, not a solution. What I would 
really like to find out is whether this error was caused by something 
under my control. If so, I'll fix it; if not, someone needs to report a 
bug to the Mandrake[*] team.

Anyway, thanks for the response.

     always makes me think of apes with purple buttocks.
