Compiling program with CMake fails

WhitetailAni · August 26, 2021

I, like some of you, enjoy XKCD.

One of my favorites is 1608, the hoverboard game. Because I use my 3DS pretty much everywhere, I wanted to see if I could get it to run on my 3DS.

I poked around the Internet and found that someone had done something kinda similar to what I was trying to do:

https://github.com/AMDmi3/hoverboard-sdl
But it's for Windows, not the 3DS. And despite my best efforts (i.e. Googling "run exe on 3ds emulator") you can't run an .exe on a 3DS. Surprise!

So I did more Googling. I was able to find that the uncompiled program used CMAKE to compile, so I looked for a 3DS CMAKE compiler. I found that, did the necessary steps to add it to the code, and ran the command that the GitHub page listed.

I got this in response. I then did... something (don't remember what) and found CMake 3.21.2. I specified the .cmake file, selected Unix MakeFiles, and hit Generate.

Crap.

And now you know why I am here. Does anyone know what the problem is here, and if it is fixable? Yes I realize that what I'm trying to do probably won't work, so if this is the case just tell me. I won't respond with "uh yes it is i know it is because of xxx youtube video".

Thanks!

As shown in the error message, you need to have DEVKITPRO installed and set in your PATH.

I believe you can get it from here: https://github.com/devkitPro/installer

One major problem that you might face is that I believe there isn't any SDL2 ports for the 3DS.

Installed DevKitPRO and now I get this:

I think there might be one:

But I'm not sure if it's done yet, and according to the author video doesn't work yet. If it does work, how would I go about adding it?

I saw a post about it, there's no video support yet, so it's pretty useless for what you want.

Could this work? I'm not sure if it supports 2.0 or not but the readme lists v2.0. It's not clear.

I heard that this one is also not finished, and the last commit was 5 years ago. You could give it a try and try to compile it.

How do I do that? I see some makefile files and I'm able to use that but the standard "makefile" file isn't there.

You need to generate the makefiles with cmake.

Tried that now, it spat out this:
