@@ -19,7 +19,14 @@ To compile ``blinky1.hex`` targeting an AVR microcontroller such as the Arduino:
docker run --rm -v $(pwd):/src tinygo/tinygo build -o /src/blinky1.hex -size=short -target=arduino examples/blinky1
Note that for microcontroller development you must flash your hardware devices
For projects that have remote dependencies outside of the standard library and go code within your own project, you will need to map your entire GOPATH into the docker image in order for those dependencies to be found::
docker run -v $(PWD):/mysrc -v $GOPATH:/gohost -e "GOPATH=$GOPATH:/gohost" tinygo/tinygo build -o /mysrc/wasmout.wasm -target wasm /mysrc/wasm-main.go
.. note::
At this time, tinygo does not resolve dependencies from the /vendor/ folder within your project.
For microcontroller development you must flash your hardware devices
from your host environment, since you cannot run ``tinygo flash`` from inside
the docker container.
