Hello, I'm French so sorry for my bad english.

I am using Weathemap 0.9 plugin with cacti

When I do php poller.php, it works but I have this :

In lib/poller-common.php, try changing the very first line from <? to <?php

I've never seen it fail the way you have it, but I do know that is the one file that doesn't have a "full" <?php tag (this is fixed in the next release).

thank you, but now, when I start it, I have this message :

Quote:

PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 2400 bytes) in /usr/local/www/apache22/data/plugins/weathermap/Weathermap.class.php on line 4377


But when I go on line 4377 of this file, I have this.

Quote:

elseif(function_exists('imagepng') && preg_match("/\.png/i",$filename))
{
debug("Writing PNG file\n");
$result = imagepng($image, $filename)
}


So I don't undestand where I can allocate 2400 bytes

It might be the default limit of 8MB in /etc/php.ini. Try to increase the row
memory_limit = 8M
to 64M or something.
