## Debug urbit with `gdb`
|
||||
|
||||
Follow the build instructions in README.md but run `make` with argument `DEBUG=yes`:
|
||||
|
||||
(If you've already built urbit first run `make clean`.)
|
||||
|
||||
make DEBUG=yes
|
||||
|
||||
Run `gdb`, while loading `bin/urbit` and its symbol table:
|
||||
|
||||
gdb bin/urbit
|
||||
|
||||
Set a breakpoint on `main()` (optional):
|
||||
|
||||
break main
|
||||
|
||||
Run your urbit comet `mycomet`:
|
||||
|
||||
run mycomet
|
||||
|
||||
Continue from the breakpoint on `main()`:
|
||||
|
||||
continue
|
||||
