Nicholas Thierry-Mieg, Thank you for your reply on Saturday Apr 23,2011. Since then I have been trying to learn how to use oprofile 0.9.4 on Centos Linux 5.5.  If I follow the following steps running as root,
 
opcontrol --shutdown 
opcontrol --callgraph=7 
opcontrol --image=/home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/Mary48.exe 
opcontrol --start 
 
/home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/Mary48.exe  

opcontrol --dump 
opreport -c > profile_info.txt 
or
opreport -l /home/frankc/DQTTest5/MatchUpLib/lirh5g_deb/libmdMatchup.so
 
I obtain the following warning:  
warning: the last modified time of the binary file does not match that of the sample file for /home/frankc/DQTTest5/MatchUpLib/lirh5g_deb/libmdMatchup.so
Either this is the wrong binary or the binary has been modified since the sample file was created.
warning: the last modified time of the binary file does not match that of the sample file for /home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/MatchUpAccurate.exe
 
I am wondering how to prevent this warning message from occuring because it indicates our profiling results may be incorrect. Thank you.
