#281 Post by gpnet »

Yes, I know.

I tried to compile on upup-476 but doesn't work. So I decided to do something in windows waiting for a new alpha release.

EDIT: I forget to say that to choice-unchoise a package you have double click on it. the buttons ADD-REMOVE probably are not useful.

also, I did not try the fixmenu command of course , and I think we also don't need /tmp/PBG_rettags.txt. check it yourself and let me know.

thanks
Giorgio

Any clues as to what is causing this....

gposil,

use:
valac --pkg gtk+-2.0 --pkg gtksourceview-2.0 texteditor.gs

which Puppy?
You will need the pet "gtksourceview".
In upup, it is included.

Please look if you have:
/usr/lib/libgtksourceview-2.0.so.0.0.0

If not:
In Puppy 4, it can be installed from:
http://ftp.nluug.nl/ftp/pub/os/Linux/di ... -2.4.2.pet

http://ftp.nluug.nl/ftp/pub/os/Linux/di ... -2.4.2.pet

Mark,

Puppy is 4.1.2

Yes gtksourceview is installed, it's needed by my other dev packages. Any other clues

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....

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.

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.

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

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.
