[syslog-ng]Conf. syntax error?

Hi, i would like to set up the syslog-ng, but by starting it, I get always syntax error messages for the first line of the config file. (it is independent from the containt of the 1. line) I made a very simly version: options { chain_hostnames(no); sync(0); }; but I got syntax error again : ... syslog-ng.conf: line 1 : syntax error near unexpected token `chains_hostnames(n' ... syslog-ng.conf: line 1 : `options { chain_hostnames(no); sync(0); };' What made I wrong? ( the syslog-ng 1.4.15 and the libol 0.2.23 was compiled from the source without errors) regards Zsolt
