Overriding parameters via defines doesn't work.

[imamushroom]

I've defined these defines in my mql file: before logger is initialised:

#undef LOG4MQL_CONFFILE
#define LOG4MQL_CONFFILE """ + StringSubstr(FILE, 0, StringLen(FILE) - 3) + "conf" + """
#undef LOG4MQL_DEFAULT_LOGFILE
#define LOG4MQL_DEFAULT_LOGFILE "my.log"

But standard log4mql.conf and log4mql.log files used.
Also, how do I disable the log4mql.conf file within the defines of the source file?
