Subject: [Caml-list] "Error while building custom runtime system"
I'm getting very strange behaviour from ocamlc when linking. Here's my
small test program. Note the '-verbose' arg:

$ ocamlc -verbose -I +perl -w s perl4caml.cma perl_init.cmo loadpage.cmo -o loadpage
$

(ie. everything is OK - it doesn't run any external programs such as gcc
or ld).

Now here's the *real* program I want to compile, note also the -verbose
arg:

$ ocamlc -verbose -w s -I +lablgtk2 -I ../lablgtk2-mozembed -I +apache -I +postgres -I +perl -I +pcre unix.cma pcre.cma lablgtk.cma gtkInit.cmo lablgtkmoz.cma postgres.cma dbi.cmo dbi_postgres.cmo perl4caml.cma perl_init.cmo lib.cmo globals.cmo database.cmo google.cmo loadpage.cmo parsepage.cmo gtkError.cmo gtkTied.cmo selection_dialog.cmo browser.cmo mainWindowControls.cmo autoPage.cmo productRankingPage.cmo salesAsmtPage.cmo commitPage.cmo pages.cmo main.cmo -o assessor

Error while building custom runtime system

I'm not using the -custom option anywhere. Ocamlc seems to react
entirely differently. First it launches gcc. Secondly (and more
importantly) it fails to link in a particular static library which I
specified when I created perl4caml.cma.

The test program also relies on the 'boot_DynaLoader' symbol, so I
don't understand why the test program works, but the real program
fails, and why ocamlc works completely differently in each case.
Something to do with the other libraries I'm using??

Rich.
