`tools/debug.sh` will run Luna in QEMU with a port open for GDB to connect to. (run `tools/build-debug.sh`, `tools/gdb.sh`, and then `tools/debug.sh` in a separate terminal for an optimal debugging experience)

Beware that running without hardware virtualization/with optimizations disabled may cause the kernel to behave differently, which is why I don't use it that often.

|

Essentially, since `run.sh` builds the toolchain if it hasn't been built, builds Luna if it hasn't been built, and runs it, you could just checkout this repo, run `run.sh`, and you're done. No need for the other scripts. Those are included for more fine-grained control/building step-by-step.

## Is there third-party software I can use on Luna?
|
||||
|
||||
Yes, actually! Check out the [ports](ports/) directory.
|
||||
Right now, there are very few ports, because our C Library is quite primitive and doesn't support complex projects.

I'm in the process of trying to port the [GNU binutils](https://www.gnu.org/software/binutils/), though.

Right now, there are very few ports, because our C Library is a bit primitive and doesn't support complex projects.
|

|

You should also keep in mind that it is not possible to compile software written in any language other than C for Luna right now.

You should also keep in mind that it is not possible to compile software written in any language other than C/C++ (and C++ was added recently, its standard library doesn't work very well) for Luna right now.
|
||||
|
||||
But feel free to try to port some program yourself and add it to the ports directory!
