Answer 1

C ++ Actor Framework由C ++ 11编写，将其中一行添加到CMakeLists.txt：

set (CMAKE_CXX_STANDARD 14)

或

set (CMAKE_CXX_STANDARD 11)

Answer 2

此示例适用于我

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)

尝试构建示例代码时出现编译错误
