Thanks Nicolas. I did follow their instructions and I got:
============================================================================ Testsuite summary for Protocol Buffers 3.6.1 ============================================================================ # TOTAL: 7 # PASS: 7 # SKIP: 0 # XFAIL: 0 # FAIL: 0 # XPASS: 0 # ERROR: 0 ============================================================================ But still getting same error message with the example: jay@Nembuntu:~/grpc/examples/cpp/helloworld$ make DEPENDENCY ERROR You don't have the grpc c++ protobuf plugin installed in your path. Please install grpc. You can find it here: https://github.com/grpc/grpc Here is what I get when trying to detect if you have the plugin: which grpc_cpp_plugin Makefile:104: recipe for target 'system-check' failed make: [system-check] Error 1 (ignored) Makefile:104: recipe for target 'system-check' failed make: *** [system-check] Error 1 jay@Nembuntu:~/grpc/examples/cpp/helloworld$ ~ When I look in the *Makefile*, I see that this error message is generated on: ifneq ($(HAS_PLUGIN),true) @echo " DEPENDENCY ERROR" @echo @echo "You don't have the grpc c++ protobuf plugin installed in your path." @echo "Please install grpc. You can find it here:" @echo @echo " https://github.com/grpc/grpc"; @echo @echo "Here is what I get when trying to detect if you have the plugin:" @echo -which $(GRPC_CPP_PLUGIN) @echo @echo endif where PROTOC = protoc PROTOC_CHECK_CMD = $(PROTOC) --version | grep -q libprotoc.3 PLUGIN_CHECK_CMD = which $(GRPC_CPP_PLUGIN) HAS_PLUGIN = $(shell $(PLUGIN_CHECK_CMD) > /dev/null && echo true || echo false So basically, it is doing a (*protoc --version | grep -q libprotoc.3*): jay@Nembuntu:~/grpc/examples/cpp/helloworld$ protoc --version | grep *-q* libprotoc.3 jay@Nembuntu:~/grpc/examples/cpp/helloworld$ But jay@Nembuntu:~/grpc/examples/cpp/helloworld$ protoc --version libprotoc 3.6.1 jay@Nembuntu:~/grpc/examples/cpp/helloworld$ protoc --version | grep libprotoc.3 libprotoc 3.6.1 Could it be that the* -q *in the grep is incorrect?
