Error when trying to use GNU profiler on AIX
Hello,

I'm trying to compile my code with ‘-pg' option in order to use GNU profiler as follows:
Code:
gcc example1.c -pg -o example1 -O2 -lc

But I'm getting this error :
Code:
collect2: gcrt0.o: cannot open as COFF file

I'm working on AIX 5.3

Thanks in advance for your help

AIX XCOFF and COFF format files, but does support the older format, COFF. I think that file is in another format.

Try the file command on gcrt0.o - file /path/to/gcrt0.o See what it tells you. This is just a start. Please post the output.

I do not know enough AIX to know if there are gcc options on AIX to handle this problem. By default .o files from gcc compilation are COFF. I dunno what you have there.

Hello Jim thanks for your reply

Apparently I don't have the gcrt0.o file in my system, I used the file command :
Code:
file /usr/lib/gcrt0.o

and I got this error:
Code:
/usr/lib/gcrt0.o: cannot open

any suggestions ?

Check /lib and /usr/ccs/lib.

Maybe it's not installed?

What does this output (if anything)?
Code:
lslpp -ha bos.adt.prof

or
Code:
lslpp -w "*gprof*"

with this command:
Code:
lslpp -ha bos.adt.prof

I got :
Code:
lslpp: Fileset bos.adt.prof not installed

and this one :
Code:
lslpp -w "*gprof*"

displays the following :
Code:
