编译器错误，esp8266 sdk固件-c代码-退出代码2

Question

我正尝试从esp8266开始，为此，我点击了以下链接：https://www.youtube.com/watch?v=AEWoeL1hH2I

在35:22，它构建了代码，但出现错误。这是我的代码。我正在使用ubuntu.using sdk。我试图检查头文件错误但没有用。

#include "osapi.h"
#include "user_interface.h"
#include "pwm.h"
#include "uart.h" 
#include "mem.h"
#include "espmissingincludes.h"


void systemInitDoneCB() {
     os_printf("Hello!\n");
 }

void user_init() {
     uart_init_2(115200, 115200);
     system_init_done_cb(systemInitDoneCB);
}

我的错误是：
