I need to profile some code running C++ on Linux. Can you guys recommend some profilers?

Use gprof.

Just compile with -pg flag (I think (but am not sure) you have to turn of optimizations though.) and use gprof to analyze the gmon.out file that your executable will then produce.

eg:

gcc -pg -o whatever whatever.c

./whatever

gprof whatever gmon.out

Same thing with g++ and cpp.
