Hi there!

It depends on what you mean.

If you want to run gdb on the entire OS, you can use Meta/serenity.sh gdb and that will let you debug the kernel.

If you want to debug an app inside SerenityOS, we have the sdb command which is similar to gdb. We also have a gdb port which you can install to run gdb. (Go to that directory and run the package.sh script to install it.)

The serenity.sh script also provides a number of other commands. Run the script without arguments for a list.

$ ./Meta/serenity.sh

Usage: serenity.sh COMMAND [TARGET] [TOOLCHAIN] [ARGS...]
  Supported TARGETs: aarch64, x86_64, riscv64, lagom. Defaults to SERENITY_ARCH, or x86_64 if not set.
  Supported TOOLCHAINs: GNU, Clang. Defaults to SERENITY_TOOLCHAIN, or GNU if not set.
  Supported COMMANDs:
    gdb:        Same as run, but also starts a gdb remote session.
                TARGET lagom: serenity.sh gdb lagom LAGOM_EXECUTABLE [-ex 'any gdb command']...
                    Passes through '-ex' commands to gdb
                All other TARGETs: serenity.sh gdb [TARGET] [KERNEL_CMD_LINE] [-ex 'any gdb command']...
                    If specified, passes the KERNEL_CMD_LINE to the Kernel
                    Passes through '-ex' commands to gdb
