gdb layout asm doesn't work on mac?

Question

$ gdb test

(gdb) start

Starting program: /private/tmp/test 
Reading symbols for shared libraries +. done    
Breakpoint 1, 0x0000000100000ec8 in main ()

(gdb) layout asm
Undefined command: "layout".  Try "help".

$ gdbtui
-bash: gdbtui: command not found

Is layout and gdbtui not available for Mac OS X? What are some alternatives?

Answer 1

According to this question there is no tui support on mac by default. So you have to compile gdb yourself with TUI enabled.
