Hi, For the last day or two I having been trying to get Valgrind/Callgrind 3.6.1 to work on Centos Linux 5.5 using a simple Fibonacci C++ program(shown below). After compiling the program using g++ -g -o MatchUpAccurate MatchUpAccurate.cpp, we run: /home/frankc/DQTTest/valgrind-3.6.1/coregrind/valgrind --tool=callgrind --dump-instr=yes --simulate-cache=yes --collect-jumps=yes ./MatchUpAccurate.exe. Then we get an error message from callgrind(shown below).
A programmer sent me an email showing me that my test program is profiled correctly on Ubuntu. I received an email from a programmer yesterday who thinks the reason that callgrind is not able to profile my C++ program on Centos Linux Version 5.5 is because of an libc conflict.
"what is the version of libc on the host? Is it a vm or physical? I guess it is gonna be a ABI/version conflict of libc. If you cannot figure it out, just report it. Chances are, a dev will be able to tell you in 5 seconds."
In order to determine what version of libc is on the Centos Linux 5.5 host, I tried: rpm -qa | grep glibc. The answer was: glibc-devel-2.5-49.el5_5.7 glibc-2.5-49.el5_5.7 glibc-headers-2.5-49.el5_5.7 glibc-common-2.5-49.el5.
We were wondering if anyone has been able to run Valgrind/Callgrind 3.6.1 on Centos Linux 5.5? Thank you.
