PDO error

[erixtekila]

From last git version, PDO raise an exception at launch :

uncaught exception: SQLSTATE[HY000] [2002] No such file or directory

The mysql.json is correct.
I achieve to connect from neko server with the same settings.

I build the output from haxe 3.2.0. Any issue with PDO there ?
