Homebrew [Preview] cpp3ds - Homebrew library and environment tutorial (for developers)

TheCruel · Sep 26, 2015

I've been working on this for a few months and will be finalizing some code within the next couple weeks that will make it usable by all homebrew developers.

https://github.com/cpp3ds/cpp3ds

cpp3ds is a port of SFML, paired with an emulator and complete CMake build environment, made specifically for 3ds homebrew development. It uses gl3ds, which is my WIP OpenGL port for the 3DS (so you can directly use OpenGL functions just like you can in SFML) but it's very limited and somewhat broken atm.

It's very easy to use and keeps your games relatively portable, assuming you don't break out of the framework and start using ctrulib directly or something. The only difficult part really is installing and getting your development environment set up properly. Many people already struggle with getting ctrulib and devkitarm set up properly, but this is more difficult since it has several dependencies (one being Qt5 for the emulator, though that can be optional).

I suggest reading the SFML tutorials if you want to learn more about what can be done with this library.

The purpose of this thread is to primarily inform people of the project's existence and upcoming release. The actual release that discusses installation and usage will be in another thread when ready.

I'm surprised I'm the first one to say that this is f**king awesome.

This is going to help lots of people that want to create homebrew. I mean, we already have Rinnegatamante's lpp-3ds but this is native and looks fresh as f**k.

I've used SFML in the past so I'm really looking forward to a stable version of this.

Thanks a lot, man!

nice tutorial

it looks great and easy (when it's you doing it).
I always use notepad++ to write codes, but having an IDE with integrated emulator/3dslink is easier to see the result.

This. Is. Amazing.

Yeah, thanks.

My goal is mostly to bring 3ds game dev up to normal modern standards. You can barely make any decent homebrew for the 3ds without learning a lot about the hardware, exploits, different tools like makerom, etc. Most game developers don't want to have to do that much, they don't want to have to read reversed engineered documentation about how to access low-level hardware stuff. Then when cpp3ds is more stable, I can focus on making gl3ds more complete (I literally just implemented the functions that SFML uses to get cpp3ds working).

Garcia98 · Sep 27, 2015

So I don't have to worry yet if I can't even compile the library, right?

Good job making this BTW

TheCruel · Sep 27, 2015

Yeah, it's missing some stuff atm. It'll be usable in a couple days. I'll post here when it's ready, then you (and anyone else interested) can give it some beta testing.

I know this is awesome and all but. Woudn't it be even more awesome if it had support for lua and the devkit arm c library! I'm thinking something like xcode where when you want to develop you get a dropdown menu (after you select create new project) then when you click on ios it say "Spritekit, etc" then you develop with that syntax/language

I'd definitely be interested in using something like this. Any update on the status of the project?

Yeah, I got a test build for everyone to test. For the sake of more simpler beta testing, I excluded the emulator (it's too buggy now anyways).

The build is linux-only (64-bit) atm, but in reality you can use this build in Windows and 32-bit linux too, but everything in the bin directory will need to be replace with Windows-built tools (makerom, bannertool, etc.)

Here are the steps to testing the beta:

1. Download the build: https://github.com/cpp3ds/cpp3ds/releases/download/v0.1/cpp3ds-linux-v0.1.tar.xz

2. Extract it anywhere you want and create a CPP3DS env variable that points to the cpp3ds folder that was extracted.

3. Using the above env variable, add $CPP3DS/bin to your PATH

4. Then you just clone the template repo and build it with the following commands:

Code:

git clone https://github.com/cpp3ds/cpp3ds-template.git
cd cpp3ds-template
mkdir build && cd build
cmake ..
make

Please let me know if anything fails.

That's freaking awesome!! I saw the Spine Demo! I will wait for this all time it need

It works fine

Have an error in "make" step in file bannertool when Generating cpp3ds-template.smdh : syntax error: "(" unexpected

Any additional detailed from output?

And did you modify anything else in CMake file (like APP_TITLE or something)?

That's my output. I didn't edit anything, only I configured the enviroment variables for DEVKITPRO,DEVKITARM, and CPP3DS.

I had this version of bannertool installed beforehand so you can try to compile this and use this instead

hahahahaha I compiled bannertool and I use it copying on the cpp3ds/bin directory. Now I get this:

Use the other version then xD
IDK why are you getting that error though as I didn't get any and I'm also using Ubuntu.

Does running "sh --version" say you're using bash? Or dash?

I think his error come from the fact that Ubuntu uses dash by default. But if you're using dash too, I must be wrong.
