If no icon.png is present, a default icon from the ctrulib folder will be used. You can place this png in your project folder (the same folder as your Makefile is in) and name it icon.png. This information is used in The Homebrew Launcher (3DSX), and in the home menu (3DS/CIA). Description of the application (Long description).Name of the application (Short description).Move the project to a folder with no spaces anywhere in its path SMDHĮvery homebrew application has an smdh file, containing additional information: make: *** No rule to make target `/c/Users/***/path/to'. unknown field 'rmdir_r' specified in initializer Your devkitARM is out of date. C:\PythonXX, where XX is the version you installed) is in your PATH as well.
If the command is python, make sure the python install directory (eg. Edit your PATH environment variable and make sure it includes this directory. It should contain the msys folder in your devkitPro installation path (eg. Your PATH environment variable is not set up correctly. (command) is not recognized as an internal or external command. You may have to manually recompile the libraries you use, if needed. Make sure to use -mfloat-abi=hard everywhere. (name) uses VFP register arguments but (name2) does not Part of your project or the libraries you use were compiled with -mfloat-abi=softfp while other parts were compiled with -mfloat-abi=hard.
You shouldn't ever use softfp for 3DS homebrew. Then select the text to copy and press the Enter key.Ĭommon errors cannot find 3dsx_crt0.o: No such file or directory In your makefile, find -mfloat-abi=softfp and change it to -mfloat-abi=hard.
Windows Tip: To copy from your command prompt, right click and choose Mark. Make sure to post all of the error output.
If you can't figure out what's wrong, feel free to make a post on the forums about it. You can ignore the warnings, they do not cause the compilation to fail. In order to find out the problem, look into the output for the lines that start with " error:" those will tell you what the problem is. This can have various causes, for example missing libraries. It is possible that sometimes your project will not compile. This is often needed when re-compiling a project. If you ever want to remove the compiled files, you can use this command: If you simply want to compile a homebrew project without (or after) editing it, you can use the make utility from the command prompt/terminal.ġ) Windows: Open a Command Prompt (Run -> cmd) Linux/Mac OSX: Open a Terminal from your applicationsĢ) Navigate to the project directory (change to the correct path) You may want to install various libraries/tools if your project requires them. It will create the environment variables automatically.ġ) Open a terminal and execute these commands:Įcho "export DEVKITPRO=/opt/devkitPro" > ~/.bashrcĮcho "export DEVKITARM=\$DEVKITPRO/devkitARM" > ~/.bashrcĮcho "export PATH=\$PATH:\$DEVKITARM/bin" > ~/.bashrc Install in C:\devkitPro\ and it will install all the latest versions of the required programs (you can disable devkitPSP, but be sure to enable libctru in devkitARM menu). There are various online tutorials and books available to learn these languages.Īlternatively, you can also write homebrew in Lua by using Lua Player Plus. The languages used to write homebrew are C, C++ and occasionally ASM. The available tools and SDK work on Windows 32/64bit and Linux. The sources are compiled to binary using GNU GCC-ARM or devkitPro with devkitARM. To develop 3DS homebrew you need a development environment consisting of tools, scripts and libraries which will be detailed below. You can find all known resources (hardware registers, syscalls, utilities) to develop your homebrew on 3dbrew. It contains shared sources, examples and libraries. If you have any questions, you can come to GBAtemp's main homebrew development and help thread. This page contains general information for 3DS Homebrew developers.
