Additional requirements
We’re not done yet. Some extra things need to be built before you can start using TinyGo.
If you haven’t already, you need to download llvm-project (for the compiler-rt sources that are needed for most architectures). Run the following commands inside your cloned TinyGo repository:
make llvm-source
To be able to use TinyGo on a bare-metal target, you need to generate some files first:
make gen-device
To be able to use TinyGo to build WebAssembly binaries, you will need to compile wasi-libc and Binaryen:
make wasi-libc
make binaryen
These commands may need to be re-run after some updates in TinyGo.
The make target for binaryen is disabled in for MacOS, and the tool can be installed with:
brew install binaryen
There are also some extra tools you will need to install, depending on your operating system. These tools are avrdude and openocd. Check the additional requirements for your operating system:
