How to use mtrace

Hi Experts,

It is in reference to one of my earlier posting about detecting memory leaks.  I tried to download mtrace from the location pointed in the web.  It had three files ( mtrace, mtrace.8, mtrace.Readme)
But, I included the header mycheck.h in my code and called mtrace( ) before a memory allocation.  Then I compiled and run the program.  There is a file with the following contents.
= Start
@ ./a.out:[0x80483ef] + 0x9afa378 0x4


But, I couldn't run the mtrace.


I changed the permission on the downloaded mtrace file and tried to execute it.

[ambuli@vader map]$ mtrace a.out test.txt
-bash: mtrace: command not found
[ambuli@vader map]$ ./mtrace a.out test.txt
mtrace: must be root


Could you please help me.

The program you downloaded isn't the mtrace that you're after.  You downloaded this:

  http://www.avici.com/documentation/HTMLDocs/03252-07_revAA/MultiCommds15.html

What you're after is the mtrace in glibc-utils.

If it has glibc then I would assume so.  A quick google check comes up with:

  http://rpm2html.osmirror.nl/CentOS-3.html

which leads to:

  http://rpm2html.osmirror.nl/centos/3.7/os/ia64/RedHat/RPMS/glibc-utils-2.3.2-95.39.ia64.html

So it appears that way.

Looked a little bit more at what CentOS is and:

 yum install glibc-utils
