I run a binary that I am trying to reverse engineer from terminal and when I try to attach it with IDA debugger it says "OOPS! Internal error 20099" occurred.

I am able to load the binary and see the disassembly.

If I click on the Debugger > Start process, it seems like it starts the process (only works if we have loaded the binary for disassembly already) but the buttons for single step are not visible (gray) and when I click on them nothing happens.

Can anyone help?

  • Hi and welcome to RE.SE! Could you please confirm with ps, top or a similar tool that the debugger and the process start? What debugger have you configured and how? – 0xC0000022L Jul 2 '20 at 14:27
