Hello Valgrind Team,
I am a new user, I am doing a "hello world" test of Valgrind but i keep hitting
this error:
--------------------------------------------------------------------------------
Ir file:function
--------------------------------------------------------------------------------
2,709 ???:getenv [/home/otro/arm_emulator/hello_x86]
1,133 ???:_int_malloc [/home/otro/arm_emulator/hello_x86]
813 ???:intel_check_word [/home/otro/arm_emulator/hello_x86]
792 ???:malloc_consolidate [/home/otro/arm_emulator/hello_x86]
783 ???:_IO_file_overflow [/home/otro/arm_emulator/hello_x86]
I have an x86_64 intel processor and running Ubuntu 14.10. I am compiling a
simple hello world program. I set the HOME and LOGNAME env variables.
This is the command that I used, as you can see I used -g and -O0 options as
suggested.
$ gcc -static -g -O0 hello.c -o hello_x86
Then I ran the executable with valgrind options, like below (the log is
attached):
$ valgrind -d -v --tool=callgrind ./hello_x86
But when I try to see the analysis with callgrind I get:
Ir

And I cant see the cost of the functions . What can be the problem? Some logs
are attached, i hope they are helpful.
Raul.
