master does not build on Alpine II

[mvorisek]

Description

see https://github.com/mvorisek/image-php/runs/6686912469?check_suite_focus=true#step:5:509

probably introduced in #8411, /cc @devnexen

original fix did not fix it - see #8674

it seems #include <linux/sock_diag.h> is somehow not supported everywhere

PHP Version

master/8.2

Operating System

Alpine

[devnexen]

Would it be possible for you to see if you have HAVE_LINUX_SOCK_DIAG_H set ? Do you have linux-headers package installed ?

[mvorisek]

I tried mvorisek@695f511 which confirms the correct/latest master is used and prev commit confirms the HAVE_LINUX_SOCK_DIAG_H is set and non-zero

CI: https://github.com/mvorisek/image-php/runs/6696224924?check_suite_focus=true#step:5:956

[devnexen]

does the header linux/sock_diag.h actually exists by the way ?

[mvorisek]

Do you have linux-headers package installed ?

this is probably the issue - official PHP for Docker installs it in https://github.com/docker-library/php/blob/f275451/Dockerfile-linux.template#L257 but with Alpine base image, it uninstalls it after the php it built immediatelly (before any extensions are built)

I install the extensions with https://github.com/mlocati/docker-php-extension-installer I will close the issue here and open it there

@mvorisek I followed the issue on the docker-php-extension-installer repo and it looks like you pushed a fix.

However, I'm still running into this issue with php:8.2.0RC2-fpm-alpine - is there any extra configuration I need to do?

[mvorisek]

not sure about the latest master, but about a month ago I built PHP 8.2 successfully.

[acelaya]

I can confirm stable php:8.2.0-alpine3.17 is still affected by this.

It took me a while to understand what to do even though required package was mentioned in this thread

So if anyone is scrolling in search of the solutions: you have to have linux-headers installed during the compilation process

apk add --no-cache linux-headers

It's required not only for sockets but also for xdebug of the 3.2.0 version
