Hello  Jianguo,

Even with streamDebug=0 the ioc still prints error messages, e.g. on
timeouts. These messages go to the console and to the log file.

But a log file is only created if  you do so in the main function of
your ioc. For example I have in streamAppMain.cc:

int main(int argc,char *argv[])
{
#ifdef DEBUGFILE
#define STR2(x) #x
#define STR(x) STR2(x)
    StreamDebugFile = fopen(STR(DEBUGFILE), "w");
#endif
    if(argc>=2) {
        iocsh(argv[1]);
        epicsThreadSleep(.2);
    }
    iocsh(NULL);
    return(0);
}

When you compile it without DEBUGFILE being set it will not create the
file. Instead all messages only go to the console.

The macro is set in the example Makefile:
# Write StreamDevice debug output to this file
CPPFLAGS += -DDEBUGFILE=StreamDebug.log

Simply comment out this line.

Best regards,
Dirk
