I'm unable to run gdb. After break main and after i type run, i get the below error and nothing happens.

Error: Error disabling address space randomization: Operation not permitted

I tried running gdb on initials program from pset2, which works perfectly fine and GDB is working fine for the same program when i run it in online ide.

Also, when i tried to run the gdb using the new gui, i get the following errors

gdbserver: linux_ptrace_test_ret_to_nx: Cannot PTRACE_TRACEME: Operation not permitted gdbserver: linux_ptrace_test_ret_to_nx: status 256 is not WIFSTOPPED! gdbserver: Error disabling address space randomization: Operation not permittedenter image description here

Please help.

  • @Kareem after executing the command, i'm no longer getting the error. But i GDB is not working as expected after i run the program in gdb it just prints out ""O hai! How much change is owed" in one go even though they are in different lines and then waits for input and nothing will work even after giving the input ( No [gdb] prompt) and i can't even quit the gdb
