[Jeckerson]

pecl install phalcon

Supported versions: 7.4, 8.0 and 8.1

[joseluisq]

Why not. BTW PR is welcome!

[niden]

Thank you @joseluisq

This will definitely help our development!

[joseluisq]

@niden awesome! Releases will come up soon.

when I try to build using the following

ARG PHALCON_VERSION="5.1.2"

RUN set -eux \
    && git clone --depth=1 --branch=v${PHALCON_VERSION} https://github.com/phalcon/cphalcon.git \
    && cd cphalcon/ext \
    && phpize && ./configure \
    && make -j$(nproc) \
    && make install \
    && docker-php-ext-enable phalcon \
    && true

Libraries have been installed in:
   /var/www/html/cphalcon/ext/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.

The PHP.ini is created at /usr/local/etc/php/conf.d/docker-php-ext-phalcon.ini using extension=phalcon Definitely, I don't know why is failing so any help should be appreciated.

[joseluisq]

The reason I would like to go with installing it in that way rather than the pecl install phalcon is that when using pecl I faced a "Virtual memory exhausted: Cannot allocate memory" error on CI.

pecl install phalcon is working in the native Docker build (x86_64) but when I use qemu for example it fails like this:

#8 4373.2  2018 | static zend_always_inline bool zend_parse_arg_array(zval *arg, zval **dest, bool check_null, bool or_object)
#8 4373.2       |                                                                ~~~~~~~^~~~

@joseluisq use build/ directory instead:

git clone https://github.com/phalcon/cphalcon.git
cd cphalcon/build
./install
docker-php-ext-enable phalcon

php --ri phalcon:

phalcon

@Jeckerson great! I will give it a try with PHP 8.1

[joseluisq]

Released on v8.1.13

[joseluisq]

BTW I will also include phalcon in the next 8.0.27 release.

[joseluisq]

Update: on PHP 8.0, phalcon is still failing with a "virtual memory exhausted: Out of memory" error via qemu. https://github.com/joseluisq/alpine-php-fpm/actions/runs/3763057946/jobs/6396274244#step:6:35992

Any idea how to make it build?

[niden]

@Jeckerson might be able to shed some more light here but from what I recall (and looking at my old Stack overflow comment)

https://stackoverflow.com/questions/22819934/compiling-phalcon-virtual-memory-exhausted-cannot-allocate-memory

• Add these flags to the make command

$CFLAGS --param ggc-min-expand=0 --param ggc-min-heapsize=8192

so that will make the script:

cd ext
phpize 
./configure --enable-phalcon CFLAGS="-O2 -Wall -fvisibility=hidden -flto -DZEPHIR_RELEASE=1 --param ggc-min-expand=0 --param ggc-min-heapsize=8192"
make -s
sudo make -s install

• Second option is to install from the ext/ folder and not the build one. From what Andres wrote in our forum years ago, the build folder has one file that has the whole build recipe for all components. That is convenient but apparently uses more memory.

  cd ext/
  ./install

• Third is to increase the swap of the container at least for the build process. The article is for Ubuntu but I am sure there is something for Alpine also.

https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

Notable is that I have the same issue with a bug report, where a member of the community sent me a repo with test code to reproduce a bug and the docker containers are in Alpine. I have several failures with it and was diagnosing it also :/

[Jeckerson]

@niden Yes, it might help.

[joseluisq]

cd ext
phpize 
./configure --enable-phalcon CFLAGS="-O2 -Wall -fvisibility=hidden -flto -DZEPHIR_RELEASE=1 --param ggc-min-expand=0 --param ggc-min-heapsize=8192"
make -s
sudo make -s install

This first option is slower and consumes all the allowed time per running job (6h). So discarded.

• Second option is to install from the ext/ folder and not the build one. From what Andres wrote in our forum years ago, the build folder has one file that has the whole build recipe for all components. That is convenient but apparently uses more memory.

cd ext/
./install

I did that https://github.com/joseluisq/alpine-php-fpm/issues/16#issuecomment-1339005919 for 8.0 as well but it failed some time ago. But curious that It works for 8.1.

• Third is to increase the swap of the container at least for the build process. The article is for Ubuntu but I am sure there is something for Alpine also.

I will investigate if I can address the problem in a similar way increasing swap space.

[joseluisq]

Minor update about Phalcon extension. Looks like you guys made possible to build the latest Phalcon 5.x for PHP 8.2. It already passed the building process for the latest PHP 8.2.4 using Phalcon 5.2.1, so I will release it today as well as PHP 8.1.17 where it already is working.

[joseluisq]

But for PHP 8.0, it is still running out of memory on KVM ones with the latest Phalcon 5.2.1, which is weird because it is not the case for 8.1 or 8.2.

[Jeckerson]

Might be due specific behaviour of PHP8.0 and our code base, as there are a lot of conditions to check PHP version.
