Linux make显示“SIGPIPE”未在此范围内声明？

Question

当我使用make命令时，它会提示以下语句。

Main. cpp: 10:9: Error: 'SIGPIPE' has not been declared in this scope
signal(SIGPIPE, SIG_IGN);
       ^
main. cpp: 10:18: Error: 'SIG_ IGN '...
signal(SIGPIPE, SIG_IGN);
                ^
main. cpp: 10:25: Error: 'signal'...
signal(SIGPIPE, SIG_IGN);
                       ^

这是main.cpp的代码。

#include <signal.h>

#include "log.h"
#include "server.h"

int main(int argc, char* argv[])
{
    

    signal(SIGPIPE, SIG_IGN);

    Log::getLog()->init();
    LOG_INFO("complete init!");
    Server server(10000);
    server.init(5);
    server.serverListen();
    return 0;
}

这是CMakeLists.txt

cmake_minimum_required(VERSION 3.0)
project(MyWebServer)
include_directories(${CMAKE_SOURCE_DIR}/server)
link_directories(/lib64)
set(CMAKE_BUILD_TYPE Release)
add_compile_options(-std=c++11)
aux_source_directory(./server SRC)
add_executable(WebServer ${SRC})

看这里介绍了SIGPIPE已经不止sig的参数中了 https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/signal?view=msvc-170
