handler.
* BUG: When a broken symbolic link is encountered, Dir() now assumes it is
a file.
* BUG: Components loaded at startup are now persistent. They are not
unloaded by the interpreter anymore. That should prevent crashes from bad
C++ libraries that have global static objects to delete. Qt can you hear
my cries?
* BUG: Now an inherited method checks that it has the same signature as the
parent method. This check is not done for a native class inheriting
another native class. C/C++ programmers are supposed to know what they
are doing. :-)

same kind than the parent symbol.

so that they do not conflict with Gambas 2 files.
* NEW: Loading a user library now automatically loads the other libraries
it depends on, as well as the components.

easily extract the property name of the parent class from the virtual
class name. For example, ".ApplicationArgs" is now ".Application.Args".

* NEW: String.IsValid() is a new method that returns if a string is a valid
well-formed UTF-8 string.
* NEW: The LIKELY() and UNLIKELY() macros do nothing now, as it seems that
recent CPUs are better than humans for branch prediction.
* NEW: Write instruction can write a bunch of bytes from a pointer address.
* NEW: Quote comma in Html$().
[GB.DB.FORM]
* BUG: Rename all Refresh() methods as Update() in all controls, so that
the Refresh() method inherited from Control is not badly overridden.

define the column labels. If they are not set, the field names are used.

* NEW: MenuButton.MenuOnly is a new property that makes the MenuButton only
pop up its menu, and never raise its Click event.

the Workspace.Children property was in conflict with the inherited
Container.Children property.
[GB.FORM.STOCK]
* BUG: Add two missing SVG files for stock icons.
* BUG: Add a missing svg stock icon for "bookmark".
* NEW: Update icons.

* BUG: Use gtk_window_set_resize_grip only with GTK+ >= 2.24.4.
* BUG: GridView.RowAt() and GridView.ColumnAt() now take the headers into
account.

integer value.

'FindAt' to match the IconView class.

Et n’oubliez pas d’installer tous les paquets de développement relatifs!
Essayez de toujours utiliser une version récente de ces bibliothèques.
Pour compiler l’environnement de développement, vous devez compiler les composants suivants :
Vous devez posséder les droits en écriture sur
/tmp
, sinon Gambas ne fonctionnera pas.
Ce paquet a été réalisé avec les versions suivantes des outils GNU sur Ubuntu 10.10:
-
automake
1.11.1
-
autoconf
2.67
-
libtool
2.2.6b
Compilation & Installation
Vérifier l’installation
Tout d’abord, assurez vous que vous avez installé toutes les bibliothèques nécessaires, et tout spécialement, tous les paquets de développement.
N’oubliez pas de consulter la page
Compilation et installation. Vous y trouverez peut être des informations spécifiques à votre distribution.
Configuration du paquet Source
Quand vous serez certains que tout est installé, entrez dans une console les phrases magiques suivantes.
'$'
represente votre invite de shell, et '...'
les
messages affichés pendant la configuration et la compilation.
Tapez d’abord ceci pour créer les scripts de configuration.
Puis cela pour analyser le système en cours et configurer le paquetage :
Si une bibliothèque ou un paquet fait défaut, vous serez alors avertis que quelques composants sont désactivés.
Il y a des explications complémentaires spécifiques à 'configure' dans le fichier INSTALL
situé au sommet de l’arborescence du code source.
Je vous invite à les lire.
Compilation
Si tout est configuré sans erreur, lancez alors cette commande pour compiler le programme :
Installation
Si tout se compile sans erreur, lancez enfin cette commande pour tout installer :
Vous devez être root
(administrateur) pour installer Gambas sur votre système.
$ su -c "make install"
Password: <Entrez ici le mot de passe root>
...
ou
$ sudo make install
Password: <Entrez ici votre mot de passe>
...
Dépannage
Si vous faites plusieurs compilations successives, après avoir mis à jour les sources à partir du dépôt Subversion par exemple, et si quelque chose échoue pendant tout ce processus, vous pouvez tenter de "reconfigurer" les scripts de configuration en entrant la commande suivante :
Puis vous pouvez exécuter à nouveau
./configure -C
Si ça ne fonctionne pas, il me faut savoir exactement ce qui est arrivé.
Pour cela, tapez la commande suivante :
$ ( ./configure -C; make; make install ) > output.txt 2>&1
Et transmettez moi le fichier "output.txt" par mail, ainsi que tout autre détail qui vous paraît utile concernant votre machine et votre distribution.
Faire tourner Gambas
Si tout s’est bien passé, tapez "gambas3" pour lancer l’ environnement de développement.
Profitez en!
