  • [gentoo-user] php different version

    From [email protected]@21:1/5 to All on Wed Oct 20 19:30:02 2021
    i am a little confused.
    it's been a few years since i last installed a php application.
    but the problems still seem to be the same ;-)

    with postfixadmin everything seems to be ok.

    when i install nextcloud it also installs php-7.3.31 and php-7.4.24,
    this is probably due to dev-php/imagick-3.5.1

    if i install roundcube with use="change-password" php-8.0.11 is needed.

    i used use="-imagemagick" for nextcloud, and
    all packages could agree on php-8.0.11.

    1.if an application requires 2 different versions this can't work,
    apache only uses one or?

    2.if in the ebuild of dev-php/imagick-3.5.1
    USE_PHP="php7-3 php7-4 php8-0"
    what does that mean?

    PHP is slotted, so it's not too unusual for multiple versions to be
    installed at the same time. An "emerge --depclean" may later remove
    the older one. But this alone is no cause for alarm.

    No, you're right. Whichever one you've eselected (if you're using
    apache's mod_php) is the one that will be used, and not all of the
    options will work with every installed PHP application. It doesn't
    make a ton of sense, but PHP is relatively stable these days. So, uh,
    good luck.

    USE_PHP="php7-3 php7-4 php8-0"

    C-language extensions like pecl-imagick are compiled against PHP. The
    USE_PHP variable declares which versions they may be compiled
    against. Then the user-facing variable PHP_TARGETS says which ones you
    want. What you ultimately get is the intersection of USE_PHP and
    PHP_TARGETS.

    1 day, 1 emerge --sync, 1 update later: php-7.4 is additionally
    installed. for a php application i would expect that 1 php version is
    enough. but depending on the use flag this is not the case for
    nextcloud and roundcube, 2 versions are installed each.

    If some application pulls in dev-lang/php when 7.3 is stable, you'll
    get 7.3. Then if later php-7.4 is marked stable, 7.4 will also be
    installed, alongside the existing 7.3 that is probably no longer
    needed afterwards.
