Description Kamil Kamiński 2016-01-25 13:06:56 UTC 
As of https://github.com/krakjoe/apcu-bc/issues/9 APCu-BC has to be loaded *after* pecl-apcu, otherwise it states that there is a missing symbol: "undefined symbol: zif_apcu_store in Unknown on line 0"

Renaming installed ini file from "apc.ini" to "bc-apc.ini" (+ symlinks in /etc/php/{module}/ext-active) fixes that problem.
In its current state, apcu_bc is not working at all ;)

Reproducible: Always

Steps to Reproduce:
1. emerge pecl-apcu_bc
2. php -v
3.
Actual Results:  
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php7.0/lib/extensions/no-debug-non-zts-20151012/apc.so' - /usr/lib64/php7.0/lib/extensions/no-debug-non-zts-20151012/apc.so: undefined symbol: zif_apcu_store in Unknown on line 0

Expected Results:  
APC working :)

Comment 1 Brian Evans (RETIRED) gentoo-dev 2016-01-27 13:39:22 UTC 
This should be fixed with apcu_bc-1.0.1-r1

(In reply to Brian Evans from comment #1)
> This should be fixed with apcu_bc-1.0.1-r1

It appears that pecl-apcu_bc is not being loaded at all in my installation. Could that be because the ini file is named /etc/php/fpm-php7.0/ext-active/bc_apcu.ini/bc_apcu.ini instead of /etc/php/fpm-php7.0/ext-active/bc_apcu.ini? (Notice the extra "bc_apcu.ini" directory.)

The following sequence of commands makes the extension appear in phpinfo() and also makes ownCloud work:
# mv /etc/php/fpm-php7.0/ext-active/bc_apcu.ini /etc/php/fpm-php7.0/ext-active/bc_apcu.ini.d
# mv /etc/php/fpm-php7.0/ext-active/bc_apcu.ini.d/bc_apcu.ini /etc/php/fpm-php7.0/ext-active/bc_apcu.ini
# rmdir /etc/php/fpm-php7.0/ext-active/bc_apcu.ini.d
# systemctl restart php-fpm@7.0
