Bazel Support
It'd be nice if the Arduino compile had Bazel (http://bazel.build) integration.
Something like:
arduino_cc_binary(
name = "example",
srcs = ["example.ino"],
board = "@io_github_arduino_arduino//boards:esp8266",
libraries = ["rs232"],
)
This would download the board definition, arduino compiler, and required libraries and build them to bazel-bin/example.bin
This might be relevant: https://opensource.google.com/projects/platformio_rules
These PlatformIO rules are working fine (I opened a few issues this past month, and the developer has been reactivate to fix them, that's nice), but have a few issues inherent to the way they're built: they're using PlatformIO as a kind of middleware, which isn't the way it's meant to be used. You cannot leverage any standard C/C++ feature that Bazel have, re-using modules with other code means writing a build target using cc_library, and a second one using platformio_library (for the same source set), it also requires to have PlatformIO in your path, which makes reproducibility hit-and-miss. In addition to that, PlatformIO's dependency management is great... for simple cases. It's a mess with nested folders.
While it's great to have those rules (they aren't perfect, but they work), I would love to see some board-specific C/C++ toolchains, native definition of Arduino libraries (Wire...), and a simple rule to manage the upload.
Agreed. Love to see Bazel supported here in a more independent way. Arduino's linker isn't great when referencing libraries outside Arduino IDE paths.
I spent a bit of time adding a Bazel toolchain that works for the ESP32. It's a bit rough around the edges, but it might be useful: https://github.com/simonhorlick/bazel_esp32
hah mate, been a while since askin, but better late than never right ? Thanks mate.
