I'm not sure if I'm doing the right thing. But I have just<br>
export PATH=$PATH:dir_to_valgind_bin<br>

And I rerun the command:<br>

Then it seems to output something, for example:<br>

<div>Yes, this worked, and it shows you have a memory overwrite in your code. You have no line</div>
<div>numbers because you deleted the *.o files without running dsymutil.</div>
<div> </div>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex; border-left:1px #ccc solid; padding-left:1ex">
And before those output, it has the following lines:<br>
--66450-- run: /usr/bin/dsymutil "./test"<br>
warning: (x86_64) /Users/hus003/projects/LS_BDRY/test/test.o unable to open object file<br>
warning: no debug symbols in executable (-arch x86_64)<br>
--66450-- run: /usr/bin/dsymutil "/Users/hus003/Documents/software/petsc-valgrind/petsc-valgrind-debug/lib/libpetsc.3.05.3.dylib"<br>

--66450-- run: /usr/bin/dsymutil "/Users/hus003/Documents/software/petsc-valgrind-install/lib/libpmpi.12.dylib"<br>

Does it mean that it's working? But what does these two warnings mean?<br>

<div>These warnings mean that symbols are missing from those libraries, which is no surprise.</div>
