Nanopb is a small code-size Protocol Buffers implementation in ansi C. It
|
|
is especially suitable for use in microcontrollers, but fits any memory
|
|
restricted system.

In order to use the nanopb options in your proto files, you'll need to
|
|
tell protoc where to find the nanopb.proto file.
|
|
You can do so with the --proto_path (-I) option to add the directory
|
|
''${nanopb}/share/nanopb/generator/proto like so:
|
|
|
|
protoc --proto_path=. --proto_path=''${nanopb}/share/nanopb/generator/proto --plugin=protoc-gen-nanopb=''${nanopb}/bin/protoc-gen-nanopb --nanopb_out=out file.proto
