Hi, I just received an email from a programmer 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. Here is an excerpt from the email:
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.
My response was: 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.
Thank you. |

Hi, I am trying to use the callgrind profiler to profile my C++ program. I am using Valgrind version 3.6,1 on Linux Centos Version 5.5 on a Intel dual processor.
I keep getting the following error(shown below) when I try to profile my program. Please tell me what I am doing wrong or what workaround I should use. I sent this message to the valgrind users mailing list early this morning. However, no one responed to email. Thank you

Note: see also the FAQ in the source distribution., It contains workarounds to several common problems., In particular, if Valgrind aborted or crashed after, identifying problems in your program, there's a good chance, that fixing those problems will prevent Valgrind aborting or, crashing, especially if it happened in m_mallocfree.c.,
If that doesn't help, please report this bug to: www.valgrind.org,
In the bug report, send all the above text, the valgrind, version, and what OS and version you are using. Thanks. |
