Hi, I am having trouble, using 'gnu profiler'. The problem is when I type:
gprof executable_name
I don't get any accumulated time for the execution of the program. The
detail of what I have done is the following.
1) I created a program named "prac2.cpp". Prac2.cpp is the following.
#include<iostream>
using namespace std;
int main(){

Hi
I have written a C++ program (Redhat Linux 7.2, gcc v2.96). The
program makes a sequence of calls to rand() after having seeded the
random number generator using srand( 0 ). Under normal circumstances,
for a given input state, the sequence of random numbers generated is
exactly reproduced each time the program is run. So, if I run the tool
3 times in succession, the path of execution is completely identical
each time as far as the...

Hello,
I would like to profile a Python program using gprof.
I already rebuilt Python with CC="gcc -pg"
../configure. So, I should be able to use gprof. How do
I do that? Should I first run Python and then gprof?
What are the steps?
Thanks a lot!

Hi,
I have a program and I want to test its execution time. When I run the
program, I can feel it runs about 4 mins, but the gprof only says the
accumlated time is 7.2 secs.
Then I use the command: "date; my program; date" and from the time
difference, I got the time 287 seconds?
I am really confused about these two numbers. Why gprof only accumlated 7.2

Hi -
I'm having some trouble trying to run PurifyPlus in windows using
cygwin. Just to try and get it rollin', I set up a basic helloworld.c
program.
I compile/link as:
gcc -c helloworld.c

I need to know the execution time of the program. Below is just an
example. I used to use gprof. But in this case, the error messsage says
"gprof : gmon.out file is missing call-graph data".
Is it possible to 'gprof' with this ? Or it will be nice if someone
introduce how to measure execution time......
Thankyou for comment.

I am using gprof, and as explain in
http://www.gnu.org/software/binutils/manual/gprof-2.9.1/html_node/gprof_18.html#SEC18
I could use the "-g -pg -a" options of gcc and then use the "-l -A"
options of gprof to obtain an anotated source listing at the basic
bloc level.
Unfortunately my version of gcc (4.0.0) does not recognize the "-a"
option.
cc1: error: unrecognized command line option "-a"

hi all ,
i want to find out how accurate is the result of gprof ? i want to find the optimized version of my program takes how much time and unoptimized takes how mch? i have tried gettimeofday(), clock() and other such functions ...but i was not getting proper consistent answer always ....
also my code is quite small so that i want to trace its runtime which is in microseconds hence i need some way to measure its exectuion time at very...

When I use gprof to profile a program, it seems never show me the profile info on c lib routines such as malloc. But sometimes, profile info on such c lib routines are also important.
I use 'gcc -g -pg' to compile the c source. Should I use other options in order for gprof to show 'malloc'?
Any more suggestions on program profiling?
Thanks!

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
