[help wanted] Cannot load builded library in PHP 8.1 using FFI

[mgluesenkamp]

Hi,

I builded the library with the help of the build instructions at https://tdlib.github.io/td/build.html?language=PHP. The build works without any problems, but I can't load my builded libtdjson.so.1.8.0 by FFI in PHP. But I always got the following error:

FFI\Exception {#634
  #message: "Failed loading '/var/www/alexa-skill-telegram/var/tdlib/libtdjson.so.1.8.0'"
  [...]

I tried several other possibilities, but I run out of ideas:

• I tried to load it as extension in PHP directly, but the error is the same. i checked is by php -v.
• I downloaded a old version of the library I found somewhere in the internet (version 1.2.0) but the error ist the same.
• If I try a "normal" library like bcmath.so it works.

Are there any restrictions in PHP to make it work or builded it wrong? Thank you for any advise!

Check that ldd /var/www/alexa-skill-telegram/var/tdlib/libtdjson.so.1.8.0 shows no missing dependencies.

You can also compare your FFI usage with code of other wrappers from https://github.com/tdlib/td/tree/master/example#using-tdlib-in-php-projects.

Ah, thank you for the ldd command. I did not know this command. It misses libssl.so.3 and libcrypto.so.3. The normal PHP docker container does not provite openssl 3 features. So I have to build my own one. Thanks! Issue can be closed. :)
