Unable to get zebra daemon running with gRPC enabled

[spk-hebbar]

I'm trying to enable gRPC on zebra daemon but ended up in following result, not sure what is that I'm missing. Please help.

This is my configure command: ./configure --prefix=/usr --localstatedir=/var/run/frr --sbindir=/usr/lib/frr --sysconfdir=/etc/frr --enable-pimd --enable-watchfrr --enable-grpc --enable-fpm --enable-protobuf

Attaching the config.log: config.log

I do have grpc installed:

#which grpc_cpp_plugin
/usr/local/bin/grpc_cpp_plugin

Just more information is needed: what if you run -M grpc (without specifying a port explicitly)? Maybe you can also enable debug northbound to see something in logs? From the above systemctl output, it's not using -M grpc:50051 option. What happens if you try running zebra manually, without watchfrr?

Thanks @ton31337 for responding.

If I try to run zebra manually, this is the error I get

#/usr/lib/frr/zebra -d -F traditional -A 127.0.0.1 -s 90000000 --vrfwnetns -M grpc
frr_init: loader error: dlopen(/usr/lib64/frr/modules/zebra_grpc.so): /usr/lib64/frr/modules/zebra_grpc.so: cannot open shared object file: No such file or directory
frr_init: loader error: dlopen(/usr/lib64/frr/modules/grpc.so): /usr/lib64/frr/modules/grpc.so: undefined symbol: OPENSSL_free
frr_init: loader error: dlopen(grpc): grpc: cannot open shared object file: No such file or directory

Looks like a missing configure option to build zebra_grpc module?
