You aren't looking for either vector.h or vector.cpp. You are looking for 'vector' (and, as I already explained, there *isn't* a .cpp file, because STL is all templates, which are *not* compiled into a library). Assuming gcc 4.1.1 in default RH installation, the 'vector' would be found in: $ rpm -ql libstdc++-devel | grep 'vector$' /usr/include/c++/4.1.1/debug/vector # this is internal debug version /usr/include/c++/4.1.1/vector # this is what client code uses. >> Sure: just add '-Wl,-verbose' and it will spit lines like this: > > Her g++ [4.1.1 20070105 (Red Hat 4.1.1-51)] didn't understand either of > those switches - not did gcc [should one use gcc rather than g++?] There are no "those switches". It's a *single* switch, spelled *exactly* this way: g++ ... -Wl,-verbose All versions of gcc (and g++) since at least 2.7.2 (which is over 10 years old) do understand this switch. Most definitely g++-4.1.1 does. >> Note that correct profiling is a bit of "black art", best performed > -pg seemed to work, but nothing seemed to be generated. running gprof, it > couldn't find gmon sometimes, or a.out when the app was compiled via gcc. You seem to be lacking the necessary skills to help her with profiling. As I said, it may require a bit of wizardry. Given that you didn't supply any details, other than "nothing seemed to be generated", it's hard to tell what may have gone wrong. Suggestion: compile a simple application (main with a couple of functions with time-consuming loops) with '-pg'. Run it to learn how gprof works, what output to expect, etc. Only then try the real application. >> Lastly, if she is on Linux/x86 or Linux/x86_64, she might get some >> significant speedup with Intel 'icc' (or not). > > No icc installed it seems. It wouldn't be (unless someone else bought a license and installed it): it's not free software. You buy it from Intel (after trying a free demo version to see if there is any benefit to be gained).
