c - PECL PCSC install on PHP 7.4

Question

I am using PHP code that relies on the package: https://pecl.php.net/package/pcsc

Finally I need to update from PHP 5 to PHP 7 (late enough). The REMI repo for CentOS unfortunately does not support PCSC for PHP7 anymore so I tried to install it manually by using the command:

pecl install channel://pecl.php.net/pcsc-0.3.1

But I get a bunch of errors (see below). Is there a way to solve this? Is there an alternative to access smart cards in PHP (did not find any)?

Errors:

Answer 1

Finally I need to update from PHP 5 to PHP 7 (late enough). The REMI repo for CentOS unfortunately does not support PCSC for PHP7 anymore so I tried to install it manually by using the command:

If the extension was compatible, it would be in the repository, as all other extensions

So this looks as a dead project.
