What is a good easy to use profiler for C++ on Linux?
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.
valgrind是一个知名的linux分析器
Zoom from RotateRight ( http://www.rotateright.com ) is what I've been using. It has a butterfly view of functions and you can double-click any function to dive into source or asm code. Build with debugging information (-g) to see your source, but you should still build and profile optimized code.
