Compile the code you want to trace with HB_TR_LEVEL_DEBUG macro, f.e.: set C_USR=-DHB_TR_LEVEL_DEBUG Before you run your application set HB_TR_LEVEL envvar to HB_TR_<level>, f.e.: SET HB_TR_LEVEL=HB_TR_DEBUG Do not set this variable if you recompile whole Harbour code with HB_TR_LEVEL_* macro or the .prg files compilation will also be traced. Use HB_TR_OUTPUT envvar if you want to redirect output to file. > Also can this debug output be directed to outer debug engines, > I mean same as I can achieve with hb_ToOutDebug() function ? I do not now hb_ToOutDebug() function. By default HB_TRACE send output to stderr and can be redirected to file. You can also run your application from parent process which redirects STDERR. I guess you want to trace GUI application. You can also use MinGW mixed mode. Just simply link Harbour application without -mwindows switch then execute it from console window. STDOUT/STDERR will be automatically redirected to this console so you can use simple printf(). best regards, Przemek _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
