Very curious

If I remember well, I had similar errors.
I then extracted the glib.pet in console (tar -xzvf glib-xxx.pet).
Then copied the files by hand.

I then tried it in a fresh setup of 4.2.0, and here this step was not required.
Maybe thepet does not install correctly, when devx_420.sfs is mounted?

It's a full hdd install, and I checked the versions in the pet against the /usr/lib files...no difference....

#289 Post by MU » Wed 03 Jun 2009, 02:49

hm, running out of ideas...

try to type
ldconfig
and reboot?

nope...no change guess i'll have to leave Vala/Genie to others...

Be certain to use 2.20 from this thread:
http://www.murga-linux.com/puppy/viewtopic.php?t=39736
That is the one I tried with success in 4.2.0.

It looks like it might be finding an older version of glib. I've attached a small program that will print the current glib version you can use to verify.

Ok I got 2.2 from the post you suggested, installed and now I get this

#294 Post by MU » Wed 03 Jun 2009, 03:30

that is good!

Nicolas did not put file operations in a

Code: Select all

try

except e: IOStreamError

so you get warnings, that is just a hint, to add that. It is not critical.

Just this is:

texteditor.gs:357.35-357.45: error: method `TextFileViewer.on_response' is incom patible with signal `Gtk.Dialog.response', expected `void on_response (Gtk.Dialo g, int)'
search_dialog.response += on_response

I must look after some sleep, what causes this.
There will be a function that needs a different parameter or returnvalue.

You can comment that line for a first test.

I had noticed the error nad commented it out but to no avail

Try changing line 361 to:

    def private on_response(search_dialog : Gtk.Dialog, response_id : int)

Strange, this is what I get in Newyearspup:

Compilation succeeded - 8 warning(s)

So I get the warnings, but compilation succeeds.
Is the gcc compiler in 4.12 equipped with different settings, so that it refuses to compile with warnings?

Then the code had to be cleaned up like this:
example:

Code: Select all

/*  -- old code --

            text : string 
            len : int 
            FileUtils.get_contents (filename, out text, out len) 
            this.text_view.buffer.set_text (text, len) 
*/

            //-- corrected code --
            try 
                text : string 
                len : int 
                FileUtils.get_contents (filename, out text, out len) 
                this.text_view.buffer.set_text (text, len) 
            except e:Error 
                stdout.printf ("%s\n", e.message)

I don't know, how to set the global compiler options, to be less restrictive.
I can try to reproduce the issues in Puppy 4.12 this evening.
But I already compiled programs with warnings - so I am curious, what is the issue in this case here.

And PupMike, thanks again

please also try the "--verbose" option of valac, like:

valac -v --pkg gtk+-2.0 --pkg gtksourceview-2.0 texteditor.gs

This tells me in addition:

Maybe your result gives us important hints.

The verbose printout did it...my versions of pango and pangocairo are much later than puppy std so I rolled them back to 2.18 and problem solved....now compiles same as your test...

Thanks for all the help Mark...

Now I can have a fiddle with this Genie gadget.

#300 Post by MU » Wed 03 Jun 2009, 04:37

cool, congratulations

Now off for some sleep...

See you again soon

Glad to hear you got it sorted out. I have the latest Pango 1.24 installed here and it works just fine btw.

Hi all,

New version without warning !

Nicolas.

gpnet · #303 Post by **gpnet** » Thu 04 Jun 2009, 07:31

Hi MU

Did you have time to give a try to the example I posted ?

Yes.
I do not have the files/folders it needs, like /root/.packages/unleashed.

So everything is empty.
But the program compiles and runs.
I installed ValaIDE 0.4svn as mentioned in a former message, as 0.5 freezes my upup.

Mark

gpnet · #305 Post by **gpnet** » Thu 04 Jun 2009, 08:41

this is the code in AppRun from pizzasgood.

Code: Select all

#ensure there's a deadpackages.txt file, and that it has stuff in it
DEADLIST="$HOME/.packages/deadpackages.txt"
if [ ! -e "$DEADLIST" ] || [ "$(cat "$DEADLIST")" = "" ]; then
	cp "$HOME/.packages/packages.txt" "$DEADLIST"
fi

So I don't understand clearly the logic behind that , but as you see it copy the content from packages.txt to deadpackages.txt and than visualize this content.
All this file must stay in $HOME/.packages . isn't it ?
