That’s the one . thanks

 

 

This one?

doc/dev/development.md

 

So apologies but that link is dead, anyone know where the contents got moved to? I can’t find any references to relevant content in the docs.

 

The protobuf-c package is installed during build (I’m using master) and gets pulled in from <daos>/utils/sl/components/__init__.py but we don’t build the protoc* binaries/full compiler to avoid overhead for something that is only required very occasionally for developer purposes (we supply the –disable-protoc configure option in the build).

 

For the moment you will need to build the compiler and plug-in yourself but we plan on providing a build flag for developers that’s need it.

This is a development tool so maybe it’s not pulled in by the default build.

 

I installed as follows:

 

git clone https://github.com/protobuf-c/protobuf-c

cd protobuf-c/

./autogen.sh

./configure --prefix=/home/tanabarr/protobuf/install PKG_CONFIG_PATH=/home/tanabarr/protobuf/install/lib/pkgconfig

make && make install

 

it is not a plug-in that ships with the stock protobuf compiler package (which ships instead with C++ plugin).

 

See the <daos>/src/proto/Makefile for some details and this will point you to the following doc if compiler is missing.

 

https://github.com/daos-stack/daos/blob/master/doc/development.md#protobuf-compiler

 

 

 

Hi Guys,

 

In https://github.com/daos-stack/daos/tree/master/src/proto/README.md, it uses “protoc -I mgmt --c_out=../mgmt mgmt/srv.proto --plugin=/opt/potobuf/install/bin/protoc-gen-c” to generate C code. In recent DAOS, I cannot find “protoc-gen-c”.

 

Do you know why?

 

Thanks.
