Ask in a Linux programming group, we only do C++ language questions here.

What do you want to profile? (security/speed/power/memory?)

For runtime/memory....
you can use quantify/purify to do code-profiling for some input
data-set.
Or, valgrind/cachegrind are free opensource tools (for input data-set).

I am not sure, if any static formal code-profiler exist, that can run
industrial grade c++ code.

When using g++, you can compile and link with -pg and then use gprof.
Run the program, it creates gmon.out upon exit. Then do gprof ./binary
../gmon.out | vim -.
