Error on build Phalcon 2.0.x with PHP 5.6 on Ubuntu 16.04

You need to make sure you're actually using PHP 5.6 and not PHP 7.0.8 which is default on Ubuntu Xerus. Looking at your compile output,

Configuring for:
PHP Api Version:         20151012

indicates you're still using PHP 7.

Well yea, 20151012 means php 7. As far as i know you need add ppa to install php 5.6.

Actually not. You can always compile it on your own, that's what I did on one production Debian Wheezy server (PHP5.4 was default). What can be an issue is to maintain both versions in Xerus. It's better to remove PHP7 then if you don't use it. But I did managed to have both 5.6 and 7.0.4(8) on the same Xerus instance. Long live PHP-FPM and Nginx! :)

Unfortunately I need the two versions of PHP (5.6 and 7). I configured NGINX to run PHP5.6 and I use Laravel in PHP7. But I need to use Phalcon in PHP5.6, how could I do that?

You know? Thanks again

Post contents of the following cmd:

file /etc/alternatives/php

Also, run the following:

whereis phpize
which phpize
phpize -v

Then i just recommend to use phpbrew, otherwise is nasty to work on few php versions.

@Jurigag: I had similar needs for Xerus, the only exception being I don't run Phalcon there, the thing is, if you point out to the correct phpize, there should be no issues to glue it with PHP5.x only, while keeping default PHP7 intact.

@donnes: How did you installed PHP5.6? From PPA or compiled it on your own?

Post results of: whereis php you should see something like: /usr/bin/php5.6

@stamster: I installed using sudo apt-get install php5.6 php5.6-dev

This is what whereis php showed:

You'd need to change /etc/alternatives/phpize to symlink to a correct PHP version, you'll find it out by using whereis phpize. In your setup case, that would be: /usr/bin/phpize5.6

I would just edit Phalcon's install script (/full/path/to/cphalcon-phalcon-v2.0.13/build/install), instead of:

#Clean current compilation
if [ -f Makefile ]; then
        make clean
        phpize --clean
fi

#Perform the compilation
phpize && ./configure --enable-phalcon && make && make install && echo -e "\nTh$

point out to the absolute path of your phpize:

#Clean current compilation
if [ -f Makefile ]; then
        make clean
        /usr/bin/phpize5.6 --clean
fi

#Perform the compilation
/usr/bin/phpize5.6 && ./configure --enable-phalcon && make && make install && echo -e "\nTh$

@stamster: I changed the install script but the same (I think) error is happening

You know that to this time you already spend you could install phpbrew, compile php 5.6 an 7 and have nice and easy way to switch betwenn them and compile phalcon without problem ? If you want to use many php versions on your server this id one and only way(despite some virtualization like docker or vagrant) you should use - https://github.com/phpbrew/phpbrew

Editing files, passing whole path etc weird things is just nasty as fck.

@Jurigag I'll try it. Just a question, If I already have PHP version on my system I need install PHP again with phpbrew?

Yes but you really should do it beacause it will be like MUCH EASIER to manage both php versions.

You have pointed out to the correct API:

Configuring for:
PHP Api Version:         20131106
Zend Module Api No:      20131226

But it seems that Phalcon build process still checks for 'advertised' PHP API path, thus it found /usr/include/php/20151012/main which is API for PHP7.

Just managing two or more php versions yourself, ESPECIALLY WHEN IT COMES TO INSTALLING/COMPILING extensions is super annoying and phpbrew is way to go, beacause he will just changes all binaries to proper.

@Jurigag @stamster Thank you so much for helping. I'm testing phpbrew, but he'is having some issues. If I can't solve I back here to bother you :P

Thanks again

No. Phpbrew increases headache right now. But the idea is cool, yes.

And, among other things, cannot install phalcon (see issue in phpbrew).

I managed to override PHP version from build/install script.

In my case I have compiled on my own latest PHP 5.6 on path /var/local So in install script, just after this part:

# Check best compilation flags for GCC
export CC="gcc"
export CFLAGS="-march=native -mtune=native -O2 -fomit-frame-pointer"
export CPPFLAGS="-DPHALCON_RELEASE"

I added: PATH=/var/local/bin:$PATH

Afterwards, Phalcon installer went to search for phpize and php-config in overriden bin path, and compilation process went through like a charm.

So, @donnes and @TrogWarZ just put there your path to bin where is your PHP version installed.

Sure, i can clone phalcon repo and compile it as usual, then copy-paste files to phpbrew directory.

$ git clone git://github.com/phalcon/cphalcon.git /tmp/cphalcon
$ cd /tmp/cphalcon/build
$ git checkout 1.3.6 # or 3.0.x for new version
$ ./install
$ cp /etc/php5/mods-available/phalcon.ini /root/.phpbrew/php/php-5.6.25/var/db/phalcon.ini
$ php -m | grep phalcon

This works. But wait, i can install like this any extension (or even just type pecl install {extension_name} sometimes).

Just pointing out two things: feature phpbrew ext install github:phalcon/[email protected] doesn't working and you need to compile phalcon manually even if you use phpbrew. That's all.

And, if you can install phalcon with this command, share, please, solution – maybe, i'm doing it wrong?

@stamster, hmm, i guess, don't understand you (-: With compiling from sources – everything is okay – i'm using update-alternatives utility for linking php/php-fpm/phpize/php-config versions. Waiting for @donnes – if phpbrew, update-alternatives, or your solution helps him or not.

What ? You don't need to copy anything men, just remove default php5 :D And use only phpbrew php. Im just doing:

cd cphalcon
phpbrew switch 5.6.19
zephir build

Thank you, phalcon installed on php from phprew 5.6.19.

cd ../zephir/parser
make clean
phpize --clean
cd ../..cphalcon
phpbrew switch 7.0.9
zephir build

Thank you, phalcon installed on php from phpbrew 7.0.9

Im not using this command, is three commands(or more) vs one such a problem ?

You don't need to copy anything men

Just make clean install (purge any php and phpbrew, remove /etc/php* and ~/.phpbrew and after that install php/phpbrew) and you'll see that after building phalcon from sources, ini-file doesn't even exists anywhere. So, you need to copy it or create by hands.

just remove default php5 :D

Why? Phpbrew requires default php5 to install. After install phpbrew and any of php version – maybe system php can be removed (tested right now).

Im not using this command, is three commands(or more) vs one such a problem ?

I don't care about number of lines and can install any extension from sources without phpbrew – it's not helping here, but in docs – i must be able to do this. So, it's defenitely a bug but i don't know where and why.

cd cphalcon && 
phpbrew switch 5.6.19 &&
zephir build

Really (o.0)? In docs i see this: apt-get install php5-phalcon but it's not working because of lack system php5. Plus, on the same page, i don't see any zephir suggestions – only "my" method above with ./install.

What's difference between "zephir-based" and "./install-based"? And why i do need additional dependency (zephir) to just use phalcon?

ps: i think, this thread betweeen us is verbalism – task "php and phalcon enabled" is done completely. I just care "how it was done" and "why real life and comments on forum differs from documentation".

I have clean install, i don't need to copy anything :) Just needed to remove system php5. You just need to uninstall php5. You can as well do cd build ./install without needing the zephir, result is the same. I'm not copying any files and it's working for me. I have have vagrant phalcon, i didn't installed zephir, also doing coding in zephir so i need zephir.

Actually removing is not even needed. Just type phpbrew switch <php version> before installing phalcon and you done, no need to copy ini file.

Okay, then why it not works before i manually locate so-file and create ini-file? What i'm doing wrong?

System php is removed and purged. Then Phalcon installed via "clone repo and ./install".
