I finally got it solved. The d coding was right. There was an 
error in the dll which caused an issue for LDC on Windows.
The SO (linux) I got working by chance. The SO has some 
dependencies to a system package. After installing this package 
by chance on my Alpine, the cryptic error message disappeared and 
everything works fine.

Kind regards
