Php – ImageMagick installed in Ubuntu Server which is found in Php.info, but not working

You need to install the ImageMagick devel package. In Ubuntu try:

sudo apt-get install libmagickwand-dev libmagickcore-dev

Oh, I fixed the problem by following the information in this forum:

Basically, I looked in my /var/log/mail.log error file and found the error message "unable to look up public/pickup: no such file or directory".

I then issued the command

sudo mkfifo /var/spool/postfix/public/pickup

I made sure sendmail wasn't still running by doing a ps -aux and killing it

root@cpu:/var/log# ps aux | grep mail
root      2363  0.0  0.5   9228  1888 ?        Ss   Jan28   0:20 sendmail: MTA: accepting connections          
root     23914  0.0  0.2   3040   792 pts/0    S+   11:33   0:00 grep mail
root@cpu:/var/log# kill 2363

I restarted postfix

sudo /etc/init.d/postfix restart

And now the PHP mail function works.
