Subject: [Caml-list] Link problems when startup from C++

Hey
My OCaml code uses Unix findlib package and I compile it like this
ocamlfind opt -package compiler-libs.common,unix -linkpkg -output-obj
-dstartup -I ../_build ../_build/qml_wrap.cmxa \
-ccopt -L`ocamlc -where` -ccopt -lunix \
DataItem.cmx MainModel.cmx MiniModel.cmx program.cmx -linkall
-o camlcode.o -verbose
Effective set of compiler predicates:
pkg_compiler-libs,pkg_compiler-libs.common,pkg_unix,autolink,native
+ ocamlopt.opt -output-obj -dstartup -I ../_build -ccopt
-L/home/kakadu/.opam/4.00.1/lib/ocaml -ccopt -lunix -linkall -o
camlcode.o -verbose -I
/home/kakadu/.opam/4.00.1/lib/ocaml/compiler-libs
/home/kakadu/.opam/4.00.1/lib/ocaml/compiler-libs/ocamlcommon.cmxa
/home/kakadu/.opam/4.00.1/lib/ocaml/unix.cmxa ../_build/qml_wrap.cmxa
DataItem.cmx MainModel.cmx MiniModel.cmx program.cmx
+ as -o '/tmp/camlstartup3ada06.o' 'camlcode.o.startup.s'
+ ld -r -o 'camlcode.o' '/tmp/camlstartup3ada06.o' 'program.o'
'MiniModel.o' 'MainModel.o' 'DataItem.o' '../_build/qml_wrap.a'
'/home/kakadu/.opam/4.00.1/lib/ocaml/unix.a'
'/home/kakadu/.opam/4.00.1/lib/ocaml/compiler-libs/ocamlcommon.a'
'/home/kakadu/.opam/4.00.1/lib/ocaml/stdlib.a'
It seems that Unix should be statically linked to 'camlcode.o'. After
that I want to build executable.
g++ -L$QT5_ROOT/qtbase/lib -lQt5Core -lQt5Qml -lQt5Quick -lQt5Gui
-L"`ocamlc -where`" -lunix \
../_build/stubs.o DataItem_c.o moc_DataItem_c.o MainModel_c.o
moc_MainModel_c.o MiniModel_c.o moc_MiniModel_c.o camlcode.o main.o
-lm -ldl -lasmrun \
-o main
And I get many error like this:
camlcode.o: In function `camlProgram__files_in_dir_1009':
(.text+0x399a): undefined reference to `unix_opendir'
/home/kakadu/.opam/4.00.1/build/ocaml/otherlibs/unix/unix.ml:644:

/home/kakadu/.opam/4.00.1/build/ocaml/otherlibs/unix/unix.ml:644:

/home/kakadu/.opam/4.00.1/build/ocaml/otherlibs/unix/unix.ml:644:
undefined reference to `unix_tcflush'
etc.
Any ideas what I have done wrong? How to link to unix correctly?
Kind regards,
Kakadu
