"Smarty: unable to write file ./templates_c/" on smarty_internal_write_file.php on line 44

[admin]

i'm tring to implement Smarty template on wordpress, and i have this problem:

<blockquote>
PHP Fatal error: Uncaught --> Smarty: unable to write file
./templates_c/wrt531ad24297cbc2.21519452 &lt;-- \n thrown in
/var/www/afric-edu/library/Smarty/sysplugins/smarty_internal_write_file.php
on line 44
</blockquote>

I first thought about permission problem and i tried this:

<blockquote>
chmod -R 777 /library/Smarty
</blockquote>

but no results...
maybe this is related to a history of absolute and relative links ? Have you an idea ?

Thanks for your help
