Я получил ошибку компиляции при попытке построить примеры кода

Question

Я столкнулся с этой ошибкой после cmake, а затем сделать. Я установил все зависимости как конфигурация.. спасибо

Answer 1

C++ Actor Framework написана на C++11, добавьте одну из этих строк в ваш CMakeLists.txt:

set (CMAKE_CXX_STANDARD 14)

или же

set (CMAKE_CXX_STANDARD 11)

Answer 2

Этот пример работает для меня

project(projectCAF)
cmake_minimum_required(VERSION 3.6)

set(CMAKE_CXX_STANDARD 11)
set(CAF_INCLUDE_ALL /usr/local/include/caf)

include_directories(${CAF_INCLUDE_ALL})
link_directories(/usr/local/lib)


macro(add executable folder source)
  add_executable(${executable} ${folder}/${source}.cpp )

  target_link_libraries(${executable} "libcaf_core.so")
endmacro()

add(one . hello)
