Hi
I am building "seL4test" using the Docker image on Ubuntu 18.04.3 LTS, a 64-bit system. After entering "../init-build.sh -DPLATFORM=x86_64 -DSIMULATION=TRUE" in a build directory within Docker it complained "Could NOT find NANOPB (missing: PROTOBUF_PROTOC_EXECUTABLE)". I wonder should I manually download and install protocol buffer compiler, protoc?
Please advise.
Thank for your help.
