[Caml-list] Re: ocamlc -linkall: problems with external functions?

[Ranjan Bagchi <ranjan@frotz.com>]

Rich,

Looks more or less identical:

$ ocamlc -linkall -custom -g -w s -I /usr/lib/ocaml/3.07/pcre -verbose dynlink.cma str.cma pcre.cma unix.cma dbi.cmo apache.cmo mod_caml_config.cmo mod_caml.cmo cgi.cmo apache_c.o wrappers.o dummy.o -o mod_caml_executable

+ gcc -Wl,-E -o 'mod_caml_executable' -I'/usr/lib/ocaml/3.07'  /tmp/camlprim3a1c34.c  '-L/usr/lib/ocaml/3.07/pcre' '-L/usr/lib/ocaml/3.07' '-lunix' '-lpcre_stubs' '-lpcre' '-lstr' 'apache_c.o' 'wrappers.o' 'dummy.o' -lcamlrun -lm  -ldl -lcurses -lpthread

$ ocamlc -custom -g -w s -I /usr/lib/ocaml/3.07/pcre -verbose dynlink.cma str.cma pcre.cma unix.cma dbi.cmo apache.cmo mod_caml_config.cmo mod_caml.cmo cgi.cmo apache_c.o wrappers.o dummy.o -o mod_caml_executable

+ gcc -Wl,-E -o 'mod_caml_executable' -I'/usr/lib/ocaml/3.07' /tmp/camlprimcecba1.c  '-L/usr/lib/ocaml/3.07/pcre' '-L/usr/lib/ocaml/3.07' '-lunix' '-lpcre_stubs' '-lpcre' '-lstr' 'apache_c.o' 'wrappers.o' 'dummy.o' -lcamlrun -lm  -ldl -lcurses -lpthread

I'll check out what Vlad had done.
