I want to use GNU gprof that comes with GCC to profile my C program. However, it returns __dyld section not supported error when I compile with the -pg flag and try to run the program:

$ gcc -pg main.c 
$ ./a.out 
dyld: __dyld section not supported in /Users/evgenii/Downloads/c_profile/./a.out

This error has been reported here. Is there a way to use the GNU profiler on macOS Mojave? I'm aware that there are alternative tools for profiling, but I want to use gprof.

I believe you're not using GCC... – Antti Haapala -- Слава Україні Jul 10 '19 at 06:39
@AnttiHaapala you are right, thanks. When I type `gcc -v` it says it's some weird Apple LLVM thing, not GNU Compiler Collection. WTF?! I want GCC! What should I do now. Install GCC? – Evgenii Jul 10 '19 at 06:52
