Neptune-Profiler-Core

Light weight profiler framework core for hypervisor based embedded system

Prerequisites

• I highly recommended to use docker as building host, you could follow Jupiter
• gRPC

• gRPC isn't aim to automotive system , many problems have been met when cross compiling to aarch64 QNX from X86_64 linux host. I have forked gRPC and abseil-cpp(it's a submodule for gRPC) which have fixed the building issues, please refer to the branches

• Installation

• Install golang , protoc-gen-doc
• Install protoc, grpc_cpp_plugin, build and install from source(version should be align with cross compiled one)
• Install protolint

• git submodule update --init

How to Build

• mkdir build && cd build
• cmake -DCMAKE_PREFIX_PATH=={where your grpc installed(build from source)} ../
• make install
