mirek seems we were trying to do the same question at the exact same moment & the forum-tool couldn't handle it
I started a second question, maybe you should delete that one

Quote:

Normally, logfile is empty, unless you put something there.

Also, LOG only works in debug mode, in release it is excluded from the final code.

(my app does keep it's own logging and there is no problem with that)

I want the log-output from theide/upp specifically this: https://www.ultimatepp.org/srcdoc$Core$Leaks_en-us.html

    StdLogSetup(LOG_COUT|LOG_FILE);
