Unable to locate package php5-phalcon

[steveobbayi]

I'm using Ubuntu 20.04 with PHP 7.4, 8.0, and 8.1. I already have Phalcon 4 installed without issues on PHP 7.4. I now want to install PHP 5 but after following these instructions:

https://docs.phalcon.io/5.0/en/installation

I get the error: unable to locate package php-phalcon5

How does one install Phalcon 5 successfully

[niden]

Does this command work? (installing from pecl)

pecl install phalcon-5.0.3

If you are not using pecl what are you using as repository?

[steveobbayi]

When using apt-get I used the ppa:ondrej/php repository

When using pecl I get the following error:

PHP Fatal error: Uncaught Error: Call to undefined function _parseFeaturesHeaderFile() in /usr/share/php/OS/Guess.php:248

I do not see the phalcon5 package in ondrej's repository:

https://launchpad.net/~ondrej/+archive/ubuntu/php/+index?batch=75&memo=75&start=75

He probably has not updated it.

As for the pear package it should work just fine - I have used it extensively for a few months now (since the first alpha actually)

php -m should show you the list of modules after you install Phalcon. phalcon should be listed there.
php -r "echo (new Phalcon\Support\Version())->get();" should output 5.0.3 (or whichever version you installed)

If the above are correct then the installation is OK.

For the stack trace you posted, I have no idea where the _parseFeaturesHeaderFile() comes from. It is certainly not in Phalcon most likely in PECL itself.

Make sure you have a proper installation of PEAR and then you can run the pecl command to install Phalcon.

[steveobbayi]

Ok I will share the Stack trace with the pear team.

As for Phalcon I guess I'm stuck with phalcon 4 for now as php7.4 -m has Phalcon 4 installed.
On my server php -m defaults to php 8.1 so the above command will not help in this situation.

I did a bit of digging and found in addition to the instructions in the docs related to Pecl install, one needs to install php-dev on the production server

Closing, this is not related to Phalcon.

Suggestion: Use Docker or Ansible to improve deployment process.
