newbiew at gcc argument

[Marcelo Roitburd]

Hi All!

I'm a newbiew , i try to make a search in internte and don't found maybe i 
can't make a good serach.my question is how in g++ or gcc i can make a 
profile of each funtion used in the code, this mean is how much time i 
spend in each function.

I know that i can do by argument, i don't want to write every entrey 
funtion time and every out funtion time..

anyone have some ideia?

thank you

marcelo

Hi Lyle!

sorry that i write about this again , but i have a question, according to 
gprof man page , when i compile the source file , i will receveid two file 
one a.out and other gmon.out.

from gprof man page:
The  profile  data is taken from the call graph profile file (gmon.out 
default) which is created by programs that are  compiled with  the  -pg  
option  of  "cc", "pc", and "f77".

but when i run 
g++ -pg test.C , only a.out are creat.

How i can creat the gmon.out? i need to write this? 

thank you ,

Marcelo

Look at the -p and -pg arguments to gcc/g++.  However, you'll also need
to look at prof or gprof, because you'll need one of those programs to
analyze the profiling data.

Thanks,
Lyle
