[Vala] Is creating dbus interfaces in type modules (plugins) broken?
Hello, I tried to develop some type modules for my program. Everything works fine initially and [ModuleInit] registered GObject dynamic classes automagically as expected. However, after I move a previously working dbus interface to that type module, I got crashes. My source code is here: http://lxde.git.sourceforge.net/git/gitweb.cgi?p=lxde/lxpanel2;a=summary A google search lead me to a similar report from others: https://mail.gnome.org/archives/vala-list/2012-September/msg00125.html Is this a known bug? Or is there anyway to overcome this? I like vala a lot and I don't want to rewrite the whole program in C again just because some little problems. Thanks in advance. ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
[Vala] Generated vapi file for a library not compilable.
Hello,
I got another issue with vala.
I moved the core part of my program to a separate library, and let the main
program call that library.
The library itself compiles correctly.
However, the genrated vapi file is not usable by the main program.
Both parts are written in vala.
The generated vapi file looks like this.
When compiling the main program with --pkg my_vapi_file, I got errors.
The generated vapi file seems to have duplicated nested namespace for
static methods like this.
namespace Lxpanel {
class Applet : Object {
static Lxpanel.Applet? from_file(string...);
}
}
If I remove Lxpanel.Applet manually and just use Applet, it works.
I like vala a lot and want to continue use it for my project, so I hope
that someone knows how to fix it. Otherwise I may have to rewrite the
program in plain C/GObject, which is a pain. :-(
All of the errors I got are like these:
VALAC lxpanel2_vala.stamp

Sorry that I forgot to paste the complete vapi file generated
It's here:

I had a similar problem doing this :

}
}
public static AppletType register () {
applet_type.id = typeof (MenuApplet); // it's PanelMenuApplet
return applet_type;
}
I found that the type *is not* MenuApplet but PanelMenuApplet,
I just removed the namespaces for Panel Applet that fixed the problem :
public class MenuApplet {
}
public static AppletType register () {
applet_type.id = typeof (MenuApplet);
return applet_type;
}

Re: [Vala] Generated vapi file for a library not compilable.
Thanks for sharing.
Manually editing the vapi file works for me too, but this is only a
workaround.
After regeneration of vapi files, the changes are gone and need to be done
again.
There must be something wrong in valac or my compiler settings.
We need a way to generate correct vapi files from vala code directly.
So, it seems that it's a bug in valac?
