Good afternoon, We are running callgrind and cg_annotate version 3.6.1 on Centos Linux Version 5.5 x86_32. One month ago Mr. Josef Weidenorfer issued a special patch that fixed callgrind on Centos Linux Version 5.5 x86_32. We can now profile complex C++ programs which use our own shared library libmdMatchup.so. However, when we use version 3.6.1 cg_annotate callgrind.out.22533 --auto = yes -I/home/frankc/DQTTest6/MatchUpLib/Source, we obtain the error. Line 1 Missing command line. callgrind.out.22533 was created using the command line: /home/frankc/DQTTest2/valgrind-3.6.1/coregrind/valgrind --tool=callgrind --dump-instr=yes --simulate-cache=yes --collect-jumps=yes ./MatchUpAccurate.exe. MatchUpAccurate.exe uses a special shared library libmdMatchup.so Could some engineer or programmer please tell us what we are doing wrong in using callgrind and cg_annotate? Please let us know if other programmers/developers have been able to use cg_annotate version 3.6.1 on Centos Linux Version 5.5 x86_32. I am including the top 50 lines of Callgrind.out.22533 below in case you have time to look at our problem. Thank you. version: 1 creator: callgrind-3.6.1 pid: 22533 cmd: ./MatchUpAccurate.exe part: 1
