I am using Ida Pro 7.0 and working with a binary (firmware) written in C++ .Fortunately there are symbols in the firmware and I know function names but Ida didn't manage to demangle all function names. I saw in the firmware ASCII string gcc2. Likely the binary was compiled using gcc2 compiler. There are a lot of important funcitons in the mangled form.

Help me out please. How Can I resolve this problem???

I tried to use idc.Demangle() func but unfortunately It can't demangle correctly.

P.S. I found that c++filt utility works correctly

  • @IgorSkochinsky Thank you Igor for your reply. I can't example the names. I'am in vacation. Can you describe the ways to do to resolve my problem. Maybe I need to play with Compiler submenu (Options->Compiler) or Demangled names. The only thing I remember that my device works under vxworks os.
