i m using gprof GNU gprof (GNU Binutils for Ubuntu) 2.21.0.20110327

i have compiled a file with this line

gfortran -g -pg test.f90

when i run gprof , it fails

gprof ./a.out 
gmon.out: No such file or directory

i have write permission o the current folder , the file itself is pretty simple , contain nothing nearly just summing 2 numbers.

why it is not running ?

Hi.

Did you execute the a.out file? ... cheers, drl

i m really so sorry , somehow it is now working , i just modified the source and recompiled and it worked , but for ur question , yes the binary was working alone for sure , i tested before i run gprof , but now i m not quit sure
anyway , i repeat my sorry , thx

at the same subject ,
i m trying to make to run gprof on a project in fortran

pgf77  -byteswapio  -fast -O3 -r8 -g -pg -c phy_phypar.f

and i repeat it for all the files needed
then i link it

pgf77  -byteswapio  -fast -O3 -r8 -g -pg addflx.o atm2land.o

stating all the files

i m root so i have all permissions and i do have it , as above i have made -pg in compile and link , i ran the binary before i ran gprof , and it is working well .
but when i run gprof it says

gmon.out: No such file or directory

again what could it be wrong ?

Hi.

I don't have access to Portland Fortran, but the man pages seem to be available at many sites.

pf[=filename]
Invoke the Profile Feedback Analyzer (PFA). This should be used in conjunction with the IPA. Use file as the name of the PFA file rather than the default pgprof.out name.

-- excerpt from man pgf77 at:
Manpage of pgf77

which suggests that the default data file name is not gmon.out. In fact, it is not clear that gprof is the appropriate command to use with pgf77 for profiling. You may need to read more on the man page or other pages relating to pgf77:

pgprof is a tool which analyzes data generated during exe- cution of specially compiled programs (using the -Mprof=func or -Mprof=lines compiler command ...

-- ibid.

Best wishes ... cheers, drl

i think i have get what is wrong
to use gprof , i have to run the program first , the execution will produce gmon , then i can run the command gprof , but actually i didn't made so , i was testing the binary then i was deleting everything , not noticing that it produce gmon , so i m just shy to say , the fault was mine
sorry again and thx for ur time
