"ocaml_beginners"::[] OCaml curses in native mode

Hi !

OCaml curses :
http://www.nongnu.org/ocaml-tmk/

builds and runs fine in byte mode.
However, about generating native mode test.opt, I get this :

pb:~/ocaml/curses/ocaml-curses-1.0.2$ make test.opt 2>&1 |more
make[1]: Entering directory `/home/fabrice/ocaml/curses/ocaml-curses-1.0.2'
make[1]: `libcurses_stubs.a' is up to date.
make[1]: `curses.cmxa' is up to date.
make[1]: Leaving directory `/home/fabrice/ocaml/curses/ocaml-curses-1.0.2'
ocamlopt -I . -o test.opt curses.cmxa test.ml
./libcurses_stubs.a(ml_curses.o): In function `winch_handler':
/home/fabrice/ocaml/curses/ocaml-curses-1.0.2/ml_curses.c:163: undefined reference to `u
ngetch'
./libcurses_stubs.a(ml_curses.o): In function `mlcurses_addch':
/home/fabrice/ocaml/curses/ocaml-curses-1.0.2/functions.c:3: undefined reference to `std
scr'
/home/fabrice/ocaml/curses/ocaml-curses-1.0.2/functions.c:3: undefined reference to `wad
dch'...

Maybe I've missed something huge ?

Thanks for any light.

Regards,

Fabrice

Have you actually got the curses/ncurses library installed?

Thanks,

The related packages installed on my debian Sid are :

pb:~/projects/chess$ dpkg -l | grep curses
ii dav-text 0.8.5-5 A minimalist ncurses-based text editor
ii libncurses5 5.6+20071124-1 Shared libraries for terminal handling
ii libncurses5-dev 5.6+20071124-1 Developer's libraries and docs for ncurses
ii libncursesw5 5.6+20071124-1 Shared libraries for terminal handling (wide charact
ii ncurses-base 5.6+20080119-1 Descriptions of common terminal types
ii ncurses-bin 5.6+20080119-1 Terminal-related programs and man pages
ii ncurses-term 5.6+20080119-1 Additional terminal type definitions
ii ninvaders 0.1.1-2 A space invaders-like game using ncurses

pb:~/projects/chess$ dpkg -l | grep curses | grep dev
ii libncurses5-dev 5.6+20071124-1 Developer's libraries and docs for ncurses

I suppose its OK about this ?

Hi Florent !

Great !
Works fine on my computer too.

I notice another small fixable thing, but in a no more maintained zone, subdir tmk, Makefile, line 43 :
replace mlcurses.cma by curses.cma, in order to build the coloured test.

Friendly,

In Debian, just apt-get install these:
$ apt-cache search curses | grep ocaml
libcurses-ocaml - OCaml bindings for the ncurses library
libcurses-ocaml-dev - OCaml bindings for the ncurses library

Oh ! I completely had missed the package.
It should be rather new.

Many thanks !
