Re: [Vala] Need Help with GLib.OptionEntry

["Gilzad Hamuni" <nt inorganic de>]

Hi Karsten,

this is happening, because you left out the third field in each entry of your array, which corresponds to the 
option flags:
http://developer.gnome.org/glib/2.28/glib-Commandline-option-parser.html#GOptionFlags

I pasted your code here and had a close look on the compiler's output. Then you can see that the errors start 
with the filename.
So the compiler complains about a string (list), two booleans (interactive and conserve) and finally an 
integer (start).

The compiler is fine with the first two entries in your array (pre and post). The difference between the 
first two entries and the others is the member 'flags':

{ "post", 0, 1,<- this one .... }

So if you provide a field value for the other entries, then you're set:

{ "list", 'l', 0, ...},
{ "interactive", 'i', 0, ...},
{ "conserve", 'c', 0, ...},
{ "start", 's', 0, ...}


Hope this helped.

Best,

Gilzad
