Can't generate protobuf files - compile errors

[cliffordjefferies]

When I try and generate the protobuf files with protoc-c esp_hosted_config.proto --c_out=. the outputs are very different and will not compile. Protoc-c has just been pulled and built The main issue is that members like has_mode are not generated yet these are referenced throughout the esp-hosted source giving errors like

home/cliffordj/src/esp-hosted/esp/esp_driver/network_adapter/main/slave_commands.c: In function 'data_transfer_handler':
/home/cliffordj/src/esp-hosted/esp/esp_driver/network_adapter/main/slave_commands.c:1934:9: error: 'EspHostedConfigPayload' {aka 'struct _EspHostedConfigPayload'} has no member named 'has_msg'
     resp.has_msg = true;

Hi @cliffordjefferies ,

We are using protoc-c 1.2.1 version. It seems protoc-c is recently updated. We will support latest version shortly.

---protoc-c --version
protobuf-c 1.2.1
libprotoc 3.0.0

Thanks, Ajita

The current pull of that repo gives

protoc-c --version
protobuf-c 1.3.3
libprotoc 3.8.0

[cliffordjefferies]

I wasted a couple of hours trying to match your version but was unsuccessful. After getting it back together I now have

protoc-c --version
protobuf-c 1.4.0
libprotoc 3.19.1
