未找到Eclipse CDT，cstdint和cinttypes类型标头

Question

我有一个非常简单的eclipse C ++项目，包含以下三个文件：

header.h

#ifndef HEADER_H_
#define HEADER_H_

#include <cstdint>
#include <cinttypes>
#include <cstdio>
#include <cstdlib>
#include <cstring>
#include <cassert>

void func1();


#endif

src.cc

#include "header.h"

void func1() {

}

main.cc

#include "header.h"

int main(int argc, char** argv) {
   return 0;
}

当我尝试编译项目时，编译会进行，但它会说：

make all
Building file: ../main.cc
Invoking: Cross G++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o" "../main.cc"
In file included from ../main.cc:8:
../header.h:11:19: warning: cstdint: No such file or directory
../header.h:12:21: warning: cinttypes: No such file or directory
Finished building: ../main.cc

Building file: ../src.cc

g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src.d" -MT"src.d" -o "src.o" "../src.cc"
In file included from ../src.cc:8:
../header.h:11:19: warning: cstdint: No such file or directory
../header.h:12:21: warning: cinttypes: No such file or directory
Finished building: ../src.cc

Building target: Test
Invoking: Cross G++ Linker
g++  -o "Test"  ./main.o ./src.o
Finished building target: Test

即它找不到标题cstdint和cinttypes，有什么我可以检查以了解为什么它们找不到？

{+ 1}}标头是在C ++ 11中引入的，GCC并不默认使用它。在项目属性中，选择cstdint下的Settings。在C/C++ Build标签的Tool Settings下，选择GCC C++ Compiler。将Dialect设置为Language standard（如果您愿意，可以设置为更新）。重新编译。
