Enable PCNTL in Ubuntu PHP - test fails

Question

I need help on How to: Enable PCNTL in Ubuntu PHP.

$ mkdir /tmp/phpsource
$ cd /tmp/phpsource


$ wget http://museum.php.net/php5/php-5.3.2.tar.gz
$ tar xvf php-5.3.2.tar.gz
$ cd php-5.3.2/ext/pcntl


$ phpize   -bash: phpize: command not found

Everything went fine until I tried to run phpize! And then I get the error '-bash: phpize: command not found' ?? Any ideas?

UPDATE ran:

$ sudo apt-get update

and then ran:

$ sudo apt-get install php5-dev

With the help of Nick I managed to finish the procedure. But 'make test' fails???

$ phpize
$ ./configure
$ make

$ cp modules/pcntl.so /usr/lib/php5/20090626/
$ echo "extension=pcntl.so" > /etc/php5/conf.d/pcntl.ini

$ make test - FAILED!

HELP: I typed 'echo "extension=pcntl.so > /etc/php5/conf.d/pcntl.ini' instead of 'echo "extension=pcntl.so" > /etc/php5/conf.d/pcntl.ini' the first time I ran this. Is that BAD?

ANY ideas!?! Carl

Answer 1

Here's what I've found in Ubuntu 12.04:

• Check your PHP.ini for the pnctl functions being disabled.

  disable_functions =     pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority
  

• phpinfo reports the function is already loaded but it will not actually work without putting the pcntl.ini file into /etc/php5/conf.d.

Sadly, this causes 'module already loaded' errors every time PHP session cleanup cron in /etc/cron.d kicks off, but PCNTL won't function without both of these pieces in place, and so far I haven't found a good solution to disable the 'already loaded' error. Its messy, and ugly, and spams my root mail, and when I can find a solution, I will post it. I've only run into this problem in 12.04 so far.

UPDATE

I hacked my /usr/lib/php5/maxlifetime script file to stop spamming with pnctl errors (PHP Warning: Module 'pcntl' already loaded in Unknown on line 0). Here are my edits - I specifically added in the 'E_DEPRECATED' line to quiet the messages.

Line 8:

    cur=$(php5 -c /etc/php5/${sapi}/php.ini -d "error_reporting='E_ALL & ~E_DEPRECATED'" -r 'print ini_get("session.gc_maxlifetime");' 2> /dev/null)

Answer 2

There is some steps like this: (my OS is debian7.2 xfce x86).

1: i install pcntl like this

#mkdir php
#cd php 
#apt-get source php5 
#cd php5-5.4.4/ext/pcntl
#phpize
#./configure
#make
#echo "extension=pcntl.so" > /etc/php5/mods-available/pcntl.ini
#ln -s /etc/php5/mods-available/pcntl.ini /etc/php5/conf.d/pcntl.ini

2: when is restart nginx or apache2, the php get one warning.

"PHP Warning: Module ‘pcntl’ already loaded in Unknown on line 0"

3: so i

"rm -rf /etc/php5/mods-available/pcntl.ini and /etc/php5/conf.d/pcntl.ini"

4: edit the "php.ini" file .

a.apache2, it's in "/etc/php5/apache2/php.ini"
b.cgi like nginx,it's in "/etc/php5/cgi/php.ini"

make the

"disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited..."
comments, add  " ; "  in front of "disable_functions".

restart your server and the warning gone.good luck.

Answer 3

On my dev machine with ubuntu 12.10 (and earlier versions too) pcntl is/was already enabled.

$ php -m | grep pcntl
pcntl

I guess thats the problem:

PHP Warning: Module 'pcntl' already loaded in Unknown on line 0

So just don't install it again.
