# This is a simple Makefile that generates client library source code
# for Google APIs using Protocol Buffers and gRPC for any supported
# language. However, it does not compile the generated code into final
# libraries that can be directly used with application code.
#
# Syntax example: make OUTPUT=./output LANGUAGE=java
#

# Choose the output directory
OUTPUT ?= ./gens

# Choose the target language.
LANGUAGE ?= cpp

# Compile the entire repository
#
# NOTE: if the "protoc" command is not in the PATH or the protobuf include
# directory is not "/usr/local/include", you need to modify this file.
