# This Makefile.protos has rules to generate go code for otlp
|
|
# exporter. It does it by copying the proto files from
|
|
# `exporters/otlp/internal/opentelemetry-proto` (which is a
|
|
# submodule that needs to be checked out) into `gen/proto`, changing
|
|
# the go_package option to a valid string, generating the go files and
|
|
# finally copying the files into the module. The files are not
|
|
# generated in place, because protoc generates a too-deep directory
|
|
# structure.
|
|
#
|
|
# Currently, all the generated code is in
|
|
# `exporters/otlp/internal/opentelemetry-proto-gen`.
|
|
#
|
|
# Prereqs: wget (for downloading the zip file with protoc binary),
|
|
# unzip (for unpacking the archive), rsync (for copying back the
|
|
# generated files).
