Unable to build googleapis in the latest version

[Nitya05]

"make LANGUAGE=cpp" for googleapis is giving the following error:

google/ads/googleads/v0/common/custom_parameter.proto:31:8: Option "php_metadata_namespace" unknown.
Makefile:46: recipe for target 'google/ads/googleads/v0/common/custom_parameter.pb.cc' failed
make: *** [google/ads/googleads/v0/common/custom_parameter.pb.cc] Error 1

Any leads on resolving this?

Yeah I'm seeing the same thing. It looks like some changes were made to the googleads protos. I'll see if I can clean up the build process. In the meantime, you should be fine to delete the google/ads/ directory.

Okay, thanks. This worked.

The option php_metadata_namespace is only known to protoc version 3.6.0 and above. gRPC v1.11.0 used in build.sh only generates protoc version 3.5.0. Using e.g. gRPC v1.15.0 fixes this issue properly by building protoc version 3.6.1.
