Hello.
I have one X-file 
Every time I run an application I’m programming, a file called gmon.out appears… Now I know that it’s quite useful and I’ve used it to improve the performance of my code… but now I’m tired. I WANT TO GET RID OF IT! 
In my Makefile there is nothing related to compile with profiling…
UNAME := $(shell uname)
DEBUG := yes
EXEC = balance
SRCS = error.c sockhelp.c server.c gyro.c servo.c main.c
CFLAGS = -O3 -Wall -pedantic
LDFLAGS = -lm -ldscud5
OBJS = $(SRCS:.c=.o)
# Compiling in Linux
ifeq ($(UNAME), Linux)
LDFLAGS += -I/usr/local/dscud5 -L/usr/local/dscud5 -lpthread
endif
# Compiling in QNX
ifeq ($(UNAME), QNX)
CFLAGS += -DQNX
LDFLAGS += -I/opt/dscud5 -L/opt/dscud5 -lsocket
endif
# Compiling with debug
ifeq ($(DEBUG), yes)
CFLAGS += -DDEBUG
endif
all : $(EXEC)
$(EXEC) : $(OBJS)
$(LINK.c) -o $@ $^ $(LDFLAGS)
clean:
rm -f $(EXEC) $(OBJS)I’ve tried in two QNX 6.3.0 machines and the same result: gmon.out appears. So, it seems it’s nothing related with any option I could have enabled without noticing…
The only “suspicious” thing is that I have a SIGINT handler that cancels the threads, closing the file descriptors and exits.
struct sigaction sa; /* To handle SIGINT */
/* Programme new handlers for SIGINT */
/* Trap SIGINT (Ctrl + C) Signal */
sa.sa_handler = sigint_handler; /* Handler for SIGINT */
sa.sa_flags = 0; /* No special flags */
sigaction(SIGINT, &sa, NULL); /* New action for SIGINT */
[...]
void sigint_handler(int sig)
{
/* Cancel the launched threads */
if (inputClientID > 0)
if (pthread_cancel(inputClientID) < 0)
err_quit("pthread_cancel inputClientID");
if (waitForInputsID > 0)
if (pthread_cancel(waitForInputsID) < 0)
err_quit("pthread_cancel waitForInputsID");
if (runServosID > 0)
if (pthread_cancel(runServosID) < 0)
err_quit("pthread_cancel runServosID");
DBGP("\nCtrl + C trapped\n");
exit(EXIT_SUCCESS);
}
In another project I have practically the same Makefile and it doesn’t throw that gmon.out. I doesn’t handle SIGINT either.
Any hint???
Thanks in advance,
Dario
