I am trying to write a toy example to use Facebook's Folly
library. The program is brought in what follows:
#include <utility>
#include <iostream>
#include <folly/Format.h>
#include <folly/futures/Future.h>
#include <folly/executors/ThreadedExecutor.h>
#include <folly/Uri.h>
#include <folly/FBString.h>
static void print_uri(const folly::fbstring &address)
{
const folly::Uri uri(address);
const auto authority = folly::format("The authority from {} is {}", uri.fbstr(), uri.authority());
std::cout << authority << std::endl;
}
int main()
{
folly::ThreadedExecutor executor;
folly::Promise<folly::fbstring> promise;
folly::Future<folly::fbstring> future = promise.getSemiFuture().via(&executor);
folly::Future<folly::Unit> unit = std::move(future).thenValue(print_uri);
promise.setValue("https://conan.io/");
std::move(unit).get();
return 0;
}
The problem is that I am not sure what are the required libraries for compiling such a program. I would be very grateful if someone can share the CMakeList.txt
file for a Folly
project.
Here is the required CMakeLists.txt
for making a Folly
project.
