I noticed that you've changed your PHP version again try it again:

which php
php -v
which php-config
php-config

and it requires gcc > 4.8

[BigFlu]

echo "extension=swoole">$YOURPATHTO/php.d/swoole.ini

[advcha]

I got the same problem. here is my way to solve it. If you change your default php version, for example to php7.2, make sure you also install php7.2-dev package sudo apt install php7.2-dev run php-config to make sure it point to php7.2 version not php7.0

before run sudo pecl install swoole, check the php extension-dir not have swoole.so file (for example your php7.2 extension-dir in /usr/lib/php/20170718). so if any swoole.so file in it, remove it manually). the rest installation steps should be straight forward and the error should be gone.

echo "extension=swoole">$YOURPATHTO/php.d/swoole.ini

@ibrahimkh94 you need to compile php_socket extension first;
