Had the same problem as above

Trying to install the graph package on Xampp (win32) gave the following error after a long pause.

‘Package “pear.php.net/Image_Graph” dependency “pecl.php.net/PEAR” has no releases’

Got it installed using ‘pear install -f -O Image_Graph-0.7.2.tgz’

Hope this is of some use to someone

That is correct. It seems as if your include_path php.ini directive isn’t set correctly.
Btw, the gnope forum (gnope.org/forum/) would be the right place for such a discussion :)

Finally got it working (after much headache).
Image_Graph wouldn’t install until i took it to a different machine which was online.
Then gd wouldn’t work until I installed the latest php with php_gd2.dll.
Then Image_Graph wouldn’t do anything, the getting started guide says:

After installation, simply include Image_Graph in your project using:
include ‘Image/Graph.php’;

Which is a total lie, you have to set the full path to the pear installation. Possibly something to do with me installing gnope recently, not sure.
Anyway its working now, thanks guys

pear default_channel is set to pear.php.net

Image_Color and Image_Canvas installed fine:

>pear install -f Image_Color-1.0.2.tgz
warning: pear/Image_Color requires PHP extension “gd”
install ok: channel://pear.php.net/Image_Color-1.0.2

>pear install -f Image_Canvas-0.3.0.tgz
warning: pear/Image_Canvas requires PHP extension “gd”
install ok: channel://pear.php.net/Image_Canvas-0.3.0

But Image_Graph just won’t install:

>pear install -f Image_Graph-0.7.2.tgz
Package “pear.php.net/Image_Graph” dependency “pecl.php.net/PEAR” has no releases

Again sorry if its off-topic
Thanks,
David.

pear install -f Image_Graph-0.7.2.tgz

That will force Image_Graph to install. Image_Canvas (which is PEAR not PECL) is optional so you should be ok.

If you really want Image_Canvas try running

pear install Image_Canvas-alpha

Also make sure that yoru default channel is set correctly.

pear config-show
pear config-set default_channel pear.php.net

Thanks for the suggestions. Ok this might be getting off-topic, but I’m having trouble installing the pear package Image_Graph. I downloaded Image_Graph-0.7.2.tgz and then typed

pear install Image_Graph-0.7.2.tgz

but it returned

Package “pear.php.net/Image_Graph” dependency “pecl.php.net/Image_Canvas” has no releases

I am online but thru a corporate firewall, but the above command should work offline (according to the pear manual)
Any ideas?
thx

David, you can use the Graph package from PEAR, and load the GD image into a GdkPixbuf via GdkPixbuf::new_from_gd();

The easy but hackish solution is to save your image data to a temp file and then use GtkImage::new_from_file(). There are (or should be) GdkPixbuf methods for loading an image directly from data in memory, but I haven’t used them. I’d have to look into exactly how they work before I can give you any info on that.

Ok will wait and see. Actually what I’m trying to do is display a simple bar chart or graph in a php-gtk2 app on the fly from some data. I was thinking of doing it in html and using MozEmbed, but I guess that can wait. In php-gtk1 I used pixmaps but it was messy… any ideas on how to do it in gtk2?

David,

Gnope currently does only include GtkSourceView but not MozEmbed. I have the mozembed dlls here, but you need the php-gtk extension for it *and* (that’s the big problem) the full mozilla files which are a 8MB rar file.
I don’t want to release it until I know which files in this archive are really needed.
