gcc-13.2 grpc 编译错误（absl-cpp build fails）

使用gcc-13.2编译absl-cpp会出现以下报错：

解决办法：

前往third_party/abseil-cpp/absl/strings/internal/str_format/extension.h该文件，添加一行代码

 #define ABSL_STRINGS_INTERNAL_STR_FORMAT_EXTENSION_H_
 
 #include <limits.h>
+#include <stdint.h> //在这个位置添加这行代码
 
 #include <cstddef>
 #include <cstring>
