question about gprof

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
secs?

Thanks.

Yan

1. Please do not post the same question multiple times. If it
doesn't instantly appear in your newsreader, that does not
necessarily mean it got lost.
2. You're in the wrong newsgroup. comp.lang.c is about the C
programming language, not gprof. You should ask in a newsgroup
dedicated to your platform. If, as it appears, that is a Unix
variant, try comp.unix.progr amming.

HTH. HAND.

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!

dear 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"

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!
