Did you try -ccopt instead of -cclib?

ocamlfind and linking with -g for stack backtrace

[Joel Reymont]

ocamlfind ocamlc -cclib -g -g -o netplex -package  
"netstring,netcgi2,unix,nethttpd-for-netcgi2,netplex" \
         -thread netplex.ml -linkpkg -g

./netplex -conf netplex.cfg

(Program not linked with -g, cannot print stack backtrace)

How do I cajole ocamlfind into passing -g to the linker?

	Thanks, Joel

It's still not working, even with "-ccopt -g". There's -g all over  
the place but I'm still not getting a backtrace.
