Nix
# A Nix flake file, mainly intended for developing TinyGo.
|
|
# You can download Nix here, for use on your Linux or macOS system:
|
|
# https://nixos.org/download.html
|
|
# After you have installed Nix, you can enter the development environment as
|
|
# follows:
|
|
#
|
|
# nix develop
|
|
#
|
|
# This drops you into a bash shell, where you can install TinyGo simply using
|
|
# the following command:
|
|
#
|
|
# go install
|
|
#
|
|
# That's all! Assuming you've set up your $PATH correctly, you can now use the
|
|
# tinygo command as usual:
|
|
#
|
|
# tinygo version
|
|
#
|
|
# But you'll need a bit more to make TinyGo actually able to compile code:
|
|
#
|
|
# make llvm-source # fetch compiler-rt
|
|
# git submodule update --init # fetch lots of other libraries and SVD files
|
|
# make gen-device -j4 # build src/device/*/*.go files
|
|
# make wasi-libc # build support for wasi/wasm
|
|
#
|
|
# With this, you should have an environment that can compile anything - except
|
|
# for the Xtensa architecture (ESP8266/ESP32) because support for that lives in
|
|
# a separate LLVM fork.
|
|
#
|
|
# You can also do many other things from this environment. Building and flashing
|
|
# should work as you're used to: it's not a VM or container so there are no
|
|
# access restrictions and you're running in the same host environment - just
|
|
# with a slightly different set of tools available.
