I am trying to build simple code with boost.asio using Bazel:

main.cpp

#include <boost/asio.hpp>
#include <boost/asio/spawn.hpp>

boost::asio::io_service io_service;

void listenUDP(boost::asio::yield_context ctx) {
    boost::asio::ip::udp::endpoint ep(boost::asio::ip::udp::v4(), 1234);
    boost::asio::ip::udp::socket sock(io_service);
    char data[128];
    for (;;)
    {
        std::size_t size = sock.async_receive(boost::asio::buffer(data, sizeof(data)), ctx);
        sock.async_send(boost::asio::buffer(data, size), ctx);
    }
}

int main() {
    boost::asio::spawn(io_service, &listenUDP);
    io_service.run();
    return 0;
}

MODULE.bazel

bazel_dep(name = "boost.asio", version = "1.83.0")

BUILD

cc_binary(
    name = "server",
    srcs = ["main.cpp"],
    deps = ["@boost.asio"]

Various dependencies of @boost.asio were broken in the Bazel Central Registry. You need to force the latest versions of them with extra lines in MODULE.bazel:

bazel_dep(name = "boost.coroutine", version = "1.83.0.bcr.2")
bazel_dep(name = "boost.context", version = "1.83.0.bcr.2")
