Unable to find 'protoc-gen-dccl' on EL 6 build
Closed this issue · 3 comments
I'm trying to build Goby 2.1.8 using DCCL 3.0.4 on Enterprise Linux 6.9, but it appears that protoc-gen-dccl is not being built. It's not obvious where this is attempted, as DCCL builds cleanly and a simple grep of its tree didn't reveal any eurekas.
What is required to generate protoc-gen-dccl ?
Note that I'm using an older version of protoc (v2.3) at this point. It is provided by the EPEL repository.

Release 2.1.8
protobuf_gen_dccl requires the stable Protobuf plugins infrastructure, which isn't available until Protobuf 2.4.0. After installing Protobuf 2.4.0 you'll either need to remove the CMakeCache.txt in dccl/build or pass -Denable_units=ON to cmake to enable building protobuf_gen_dccl
Goby >= 2.1.6 requires protobuf_gen_dccl for the static units support (http://libdccl.org/idl.html#idl-units).
So you'll need Protobuf >= 2.4.0 (preferred) or use Goby <= 2.1.5.
Great, thanks! I'll identify a way forward to get Protobuf 2.4+ running on EL 6.
