Bug 475916 – sys-apps/portage - Error output for USE_EXPAND flags is unclear towards the user; doesn't suggest whether to do PHP_TARGETS="php_targets_php5-3" or PHP_TARGETS="php5-3", leaves user confused.

[Description Juergen Rose 2013-07-06 08:03:31 UTC]

'emerge -uvDN world' fails with:

root@impala:/root(17)# emerge -uvDN world
...
!!! The ebuild selected to satisfy "dev-php/pecl-ps" has unmet requirements.
- dev-php/pecl-ps-1.3.6-r1::gentoo USE="examples" PHP_TARGETS="-php5-3"

  The following REQUIRED_USE flag constraints are unsatisfied:
    php_targets_php5-3

  The above constraints are a subset of the following complete expression:
    any-of ( php_targets_php5-3 )

(dependency required by "app-benchmarks/phoronix-test-suite-4.6.1" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])

Setting PHP_TARGETS="php_targets_php5-3" in /etc/make.conf does not help:

root@impala:/root(21)# grep php_targets_php5-3 /etc/make.conf
PHP_TARGETS="php_targets_php5-3"

dev-php/pecl-ps-1.3.6-r1 was built with the following:
USE="examples" PHP_TARGETS="php5-3"




Setting PHP_TARGETS="php5-3" in /etc/make.conf seems to help. The first error message was a little bit misleading.

[Comment 1 Tom Wijsman (TomWij) (RETIRED) 2013-07-06 18:04:00 UTC]

At the least, it would be nice if Portage also suggests to change the variable.

For example:

    The minimal make.conf change needed to satisfy the requirements is:

        PHP_TARGETS="php5-3"

And optionally we could add:

    Possible other combinations are:

        ... enumerate all possible satisfied combinations for PHP_TARGETS ...

Expanded dependency output is nice for devs, but is confusing towards users.

[Comment 2 Tony Butler 2014-11-05 17:50:34 UTC]

This message seems to be repaired, currently gives:

 * Make sure that PHP_TARGETS in /etc/make.conf includes php5-5 in order 
 * to compile extensions for the 5.5 ABI

However if the is no PHP_TARGETS defined at all, and you're only installing php freshly, this should be assumed.  Took me a while to figure out I was missing a definition that should be the default.

Also of note, it doesn't show PHP_TARGETS on that line like every other USE_EXPAND using package does.

That's because dev-lang/php doesn't use PHP_TARGETS. PHP_TARGETS is for packages like dev-php/pecl-ps that require one or more php implementations.
