BORIS won't start

[dangelov]

I get the following error when I try to start it. I cloned the repo, cd'ed and tried to run it.

Dinos-MacBook-Pro:bin dinoangelov$ ./boris

Fatal error: Call to undefined function Boris\pcntl_signal() in /Users/dinoangelov/Library/Developer/boris/lib/Boris/Boris.php on line 110

You need a PHP that has been compiled with the pcntl functions to run Boris. The PHP that ships with OS X is notoriously lacking. Any of the mainstream Linux distros should provide suitable PHPs, otherwise you may install your own on OS X (which is what I do).

[dangelov]

In case some other people run into the same issue, here's a small guide I wrote for OS X. Feel free to grab the relevant bits or link to it if you'd like to add a bit more instructions for the OS X installation.

Boris fails when running on a Docker container:

Is any special permission needed to use these PHP extensions boris require?

@juniorz I just ran into the same problem. In my case I needed to remove the pcntl functions from disabled_functions in my php.ini.

[juniorz]

Thank you @chasingmaxwell. It worked with:

$ grep -E '^disable_functions' /etc/php5/cli/php.ini | sed -r 's/pcntl_(signal|fork|waitpid|signal_dispatch),//g' > /etc/php5/cli/conf.d/99-boris.ini

on an Ubuntu box.

phpinfo() shows php compiled with pcntl. running test.php with pcntl_signal() returns "expecting arguments...." instead of "function not found" so I know I have the function set. Moreover, I'm running PHP 5.4

I'm guessing this is boris's implementation involving namespaces that's triggering this error. It's not my PHP version.

the #!/usr/bin/php -q was forcing the wrong version of PHP. fixed the path, everything is fine.

I commented out the line in my php.ini and then restarted apache. No dice. I still get the error. Welp.

Since I found this page from Google searching my problem, a bit different from dangelov's message: PCNTL support seems to be missing or disabled. See https://github.com/d11wtq/boris/issues/29 for details

Went through some kind of upgrade on the Mac. I'm positive it was upgrades in (Home)brew when the php package/formula was being renamed to php@5.6, but somehow my shell started using the system /usr/bin/php, that mentioned above, lacks the compilation configuration to include PCNTL functions, along with many others.

I still had that PHP installed, but didn't have the paths set-up in my terminal (fish), so I just added them with the commands mentioned in the brew PHP package's info text.

Maybe I was using the system one this entire time until now, but that's strange because I was successfully using boris until this situation occurred.

Hello from the future!

I discovered by way of this Stack Overflow answer that MacPorts and Homebrew both seem to have phpXY-pcntl packages available.

In my case, this let me use boris on my Mac running Mojave (10.14.6):

$ sudo port install php73-pcntl
--->  Computing dependencies for php73
⋮
--->  Some of the ports you installed have notes:
  php73 has the following notes:
    You may need to update your php.ini for any changes that have been made in this version of php73. Compare /opt/local/etc/php73/php.ini with
    /opt/local/etc/php73/php.ini-development (if this is a development server) or /opt/local/etc/php73/php.ini-production (if this is a production server).
  php73-pcntl has the following notes:
    php73-pcntl should not be enabled within a web server environment. Unexpected results may occur if any process control functions are used within a web server
    environment.

$ php -m | grep pcntl
pcntl

Note the warning that this version of PHP should not be used in a production environment, so just be aware of that. I'm only using the interpreter from the command line, so this was fine for me.

Hope this helps!

Update: It was also necessary to sudo port install php73-posix, otherwise I was getting errors like:

Fatal error: Uncaught Error: Call to undefined function Boris\posix_getpid() in /path/to/boris/lib/Boris/EvalWorker.php:113
