docker environment for: clang + libc++ + boost

How to build the container:

To build the docker images:

make build
make push

To test the container run a sample built from c++ source code:

make sample-run

How to use in another project:

1. Create docker-compose.yml with a volume mount

version: '3.0'
services:
   clang-libcpp-boost-env:
      image: shri314/clang-libcpp-boost
      entrypoint: sleep infinity
      container_name: clang-libcpp-boost-env
      restart: always
      volumes:
         - .:/src

2. Create a Makefile (using make)

DOCKER_ENV_CMD = docker exec -it clang-libcpp-boost-env

all: sample-run

up:
	docker-compose up -d

down:
	docker-compose down

sample: up sample.o
	$(DOCKER_ENV_CMD) clang++ -std=c++2a -fcoroutines-ts -stdlib=libc++ -lc++abi -o sample sample.o

sample.o: up sample.cpp
	$(DOCKER_ENV_CMD) clang++ -std=c++2a -fcoroutines-ts -stdlib=libc++ -c sample.cpp

sample-run: sample
	$(DOCKER_ENV_CMD) ./sample

clean:
	rm -f sample sample.o

3. Put your sources in current directory (available as /src inside the container)

#include <iostream>
#include <optional>
#include <string>
#include <experimental/coroutine>
#include <boost/lexical_cast.hpp>

int x = 0;

std::optional<int> foo() {
   return []() {
      return x++;
   }();
}

int main() {
   std::cout << "Hello " << *foo() << "\n";
   std::cerr << "Hello " << *foo() << "\n";
   std::clog << "Hello " << boost::lexical_cast<std::string>(*foo()) << "\n";
}

4. build

make
