How to check whether my debugger does support visualizers?
To check whether your debugger supports visualizers run below commands on machine where GDB is located: gdb –interpreter=mi -list-features The output should be similar to this one: ^done,features=[“frozen-varobjs”,”pending-breakpoints”,”python”] Visualizers are supported only by debugger which does return “python” among list of features. You need at least GDB 7.0. Sometimes it doesn’t have python support enabled, then you can enable it in sources and rebuild GDB on your machine.
