Current behavior

No RFC Call possible

How to reproduce

Try to compile and install the library on SUSE SP3 with apache 2 and PHP Version 7.4.30.

Expected behavior

If the extension is compiled and installed correctly should works in runtime too.

[gkralik]

Try with the latest version in main (or 2.0.0-beta2). The 1.x versions really are for PHP 7.2 only and are not maintained anymore.

[ynnoig]

I have already tried without success! :(

... But... I have other systems running in docker apache-buster php7.4 with 1.4.0 Version and everything works without problems.

I think that maybe is more related to SUSE 15 SP3 and php version 7.4.30?

I searched yesterday the whole afternoon and evening about this problem, but no success... nothing found.

[gkralik]

Might be, I haven't use SUSE in more than a decade. I'll have a look when time allows.

[ynnoig]

Hi @gkralik, did u get time to test with SUSE?

[gkralik]

I forgot about this, sorry. I do not have any spare time at the moment to investigate this. PHP 7.4 has reached end of life, so it's unlikely I will fix this unfortunately.
