This error means your samba was compiled for qnx 6.2.
I know cdm has several packages in /repository/6.1 directory actually compiled for 6.2. Apparently, you hit the jackpot
I wouldn’t be surprised you found mritun’s version working. He is one of the few people who still use qnx 6.1. His reason is different from you. Maybe we should open up another thread “why I am still using qnx 6.1” so that QSSL can fix those and everybody can upgrade
