C# GRPC extensions for Linux

• Arm32 [armhf]
• Arm64 [aarch64]

Original Idea

https://github.com/erikest/libgrpc_csharp_ext

You can use already compiled files (which should be Linux OS agnostic)

or

Build your own C# ext files for GRPC

Install necessary deps for building

Debian based OS (Ubuntu/Debian/LinuxMint/...)

###
#Install Tool Chain
###

sudo apt-get install build-essential autoconf libtool pkg-config
sudo apt-get install libgflags-dev libgtest-dev
sudo apt-get install clang libc++-dev
sudo apt-get install cmake

Arch based SO (Arch/Manjaro/...)

###
#Install Tool Chain
###

sudo pacman -S build-essential autoconf libtool pkg-config base-devel
sudo pacman -S clang cmake go

Lets clone from GitHub and build

Replace: --branch v1.27.x with branch you actually need

#!/bin/bash

###
#Get gRPC Source Code
###

git clone https://github.com/grpc/grpc.git --branch v1.27.x
cd grpc
git submodule update --init

###
#Compile libgrpc_csharp_ext target
###

#create location for build files
mkdir -p cmake/build
cd cmake/build

#setup the build files
cmake -DgRPC_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE="${MSBUILD_CONFIG}" ../..

#compile libgrpc_csharp_ext.so 
make -j4 grpc_csharp_ext

Finally copy generated ext to some directory

In this case it will copy generated file to directory where you cloned grpc from github

#Copy the file back to repository root and rename it to what gRPC.Core currently looks for
cp libgrpc_csharp_ext.so ../../../libgrpc_csharp_ext.x64.so

Notes

WARNING: GRPC dont support officially arm32, but compiled .so for armhf should work anyway on specific versions of GRPC

LinuxArm64 (aarch64)

Published NetCore app as self-contained -> linux-arm64

Rename generated .so into -> libgrpc_csharp_ext.x64.so

Published NetCore app as framework-dependant -> linux-arm64

Rename generated .so into -> libgrpc_csharp_ext.arm64.so

LinuxArm32 (armhf)

Published NetCore app as self-contained -> linux-arm

Rename generated .so into -> libgrpc_csharp_ext.x86.so

Published NetCore app as framework-dependant -> linux-arm

Rename generated .so into -> libgrpc_csharp_ext.arm.so
