Attempting to build ceph on ubuntu.

Hi. I've gone through much of the build process documented under Build Prerequisites and Building Ceph. I see a build failure when I run ninja -j3. The failure seems to occur when the grpc_tools are being built. Can someone please provide a suggestion on how to get past this. My hope is to get CEPH built, and then to run the test server so that I can begin to dig into CEPH modules, perhaps even running specific components in a single step debug environment. I am building on ubuntu: 24.04.2 I cloned ceph main about 2 days ago. Thanks for any help.
