I got this error message when I want to upgrade php from 5.6 to 7.4

php: error while loading shared libraries: libargon2.so.1: cannot open shared object file: No such file or directory

I sent these commands

wget ftp://ftp.slackware.com/pub/slackwar...3-x86_64-1.txz

upgradepkg php-7.4.3-x86_64-1.txz


nano /etc/httpd/mod_php.conf

# LoadModule php5_module lib64/httpd/modules/libphp5.so
LoadModule php7_module lib64/httpd/modules/libphp7.so


/etc/rc.d/rc.httpd stop
/etc/rc.d/rc.httpd start

php -v

php: error while loading shared libraries: libargon2.so.1: cannot open shared object file: No such file or directory

please guide me about this problem

Installing packages for Slackware current in Slackware 14.2 often leads to failures, in this case because in current php depends on argon2, not shipped in 14.2. Don't do that.

thanks
but what can I do?
I cannot run WooCommerce and other plugins on Wordpress that need PHP more than 7 Version

respectfully

You'll have to build the php version you need on the 14.2 system: https://mirrors.slackware.com/slackw.../source/n/php/

I think files are the same as my mentioned files, I got a problem on it

I saw these files before

Is there any different method to install and compile files over there?

Maybe some of the methods will be different from straight ways

They are not the same. You installed the binary package compiled on a -current system onto a 14.2 system. That's not expected to work.

What you need to do is compile a package with those php sources on a 14.2 system.

As Robbby mentioned, taking a package compiled on a different system (even if it's just a different version of Slackware) is not guaranteed to work. This is because that package is compiled against the library versions that are installed when compiled. In the case of your issue, argon was added to the distro after 14.2 was released. It is possible that installed argon will make that error go away (assuming the argon you install is the same version php was compiled against), but even if it loads without errors, it might still be broken or have missing features.

This is why it is best to build the package specifically for your version of Slackware.
