Bonjour,
Je suis en pleine decouverte de FreeBSD et j'utilise Emacs Tuareg pour coder du OCaml.
J'aimerai utiliser la librairie lablgtk2 mais j'ai plusieurs soucis.

Quand j'entre la commande: pkg info
Je trouve:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

gtk-3.8.2_1                    Gimp Toolkit for X11 GUI (current stable version)
gtk-2.24.19_2                  Gimp Toolkit for X11 GUI (previous stable version)
gtk-engines2-2.20.2_1          Theme engine for the GTK+-2.0 toolkit
gtk-update-icon-cache-2.24.19  Gtk-update-icon-cache utility from the Gtk+ toolkit
gtk-xfce-engine-3.0.1          Xfce gtk theme engine
gtksourceview2-2.10.5_1        A text widget that adds syntax highlighting to the GtkTextView widget
gtkspell-2.0.16_4

Je trouve aussi des lib gnome et x11, bref j'ai ce qu'il faut.

Ce pendant quand je veux compiler un fichier utilisant ocaml et gtk2, je recois un message type:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Error: Unbound module GMain
ou

Voici mes fichiers:

OCAMLMAKEFILE = ../OCamlMakefile
 
SOURCES = menu.ml
RESULT = menu
PACKS = lablgtk2
THREADS = yes
OCAML=ocamlc
 
include $(OCAMLMAKEFILE)

Ma commande de compilation:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

ocamlc -I +lablgtk2 -o menu lablgtk.cma gtkInit.cmo menu.ml

La reponse:

Code :

File "menu.ml", line 2, characters 8-18:
Error: Unbound module GMain

Toute aide sera grandement appreciee!
Merci d'avance

Cela peut prendre, disons, un certain temps, avant qu'un membre utilisant une configuration 100% identique (gorgonite le diablotin ) ne te réponde.

En attendant je te propose d'essayer ceci :

1. Ouvre un shell dans le répertoire de menu.ml
2. Entre la commande (compilation vers du code natif) :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

ocamlopt.opt -w s -o menu -I +lablgtk2 lablgtk.cmxa menu.ml

En fait c'est un probleme d'installation de lablgtk2.

Version que j'ai download:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

lablgtk-2.18.0

Le ./configure donne ca:

Que faire?
Google ne m'aide pas vraiment.

Bon ok c'est pas évident.
C'est écrit dans le README, si tu n'as pas findlib tu dois faire make old-install
