Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables KERBEROS_CFLAGS
and KERBEROS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

メモリ使用量
PHP の OPCache エクステンションのレビューから
The size of the memory segment can be told using the opcache.memory_consumption INI setting (Megabytes). Size it big, don't hesitate to give space. Never ever run out of shared memory space, if you do, you will lock your processes, we'll get back to that later.
Size the shared memory segment according to your needs, don't forget that a production server dedicated to PHP processes may bundle several dozens of Gigabytes of memory, just for PHP. Having a 1Gb shared memory segment (or more) is not uncommon, it will depend on your needs, but if you use a modern application stack, aka framework based, with lots of dependencies etc... , then use at least 1Gb of shared memory.
Having that in mind, set opcache.memory_consumption to a value high enough to avoid filling it up (as long as your RAM usage allows you to), and then monitor the OPCache to adjust that value to its optimal size. As the total size of the PHP files in a standard Moodle 3.6 is almost 90MB, setting this value higher than that can be a good idea. Take into account that the PHP files of the plugins and those on the MoodleData folder (language pack files...) also count, so these values can be different on each installation. If you have several instances of Moodle you should multiply that value by the number of instances.
Tip: If using Linux, you can know the total size of the PHP files of a folder using this command:
The maximum number of keys (and therefore scripts) in the OPcache hash table. The actual value used will be the first number in the set of prime numbers { 223, 463, 983, 1979, 3907, 7963, 16229, 32531, 65407, 130987 } that is greater than or equal to the configured value. The minimum value is 200. The maximum value is 100000 in PHP < 5.5.6, and 1000000 in later versions.
As Moodle 3.6 contains almost 10.000 php files it is recommended above that opcache.max_accelerated_files should be set to 10000 to accommodate this (16229 will actually be used as per the explanation above). If you have several instances of Moodle you should multiply that value by the number of instances.
If many additional plugins are installed so that your total PHP files exceed 16229 then the next most suitable value for max_accelerated_files should be used. Tip: If using Linux, you can know the total PHP files of your Moodle using this command:
find ./ -type f | grep -E ".*\.php$" | sed -e 's/.*\(\.[a-zA-Z0-9]*\)$/\1/' | sort | uniq -c | sort -n
3 Opcache 管理プラグイン
Opcache management message.png
You may consider installing the additional Opcache management - Moodle plugin which adds a PHP Opcache management GUI to Moodle site administration, a CLI tool to reset PHP Opcache and a Nagios check for PHP Opcache.
