为什么英特尔选择将段的基数和限制划分为段描述符中的不同部分而不是使用连续位？
见http://css.csail.mit.edu/6.858/2014/readings/i386/s05_01.htm的图5-3
为什么它们不将位地址存储在位0到31中,限制位32到51并将剩余位置用于其他位(或某些类似的布局)？
无法使用更新站点在RAD 8.5.1中安装Maven.
无法完成安装,因为找不到一个或多个必需的项目.正在安装的软件:m2e - Eclipse的Maven Integration 1.0.0.20110607-2117(org.eclipse.m2e.feature.feature.group 1.0.0.20110607-2117)缺少要求:m2e Marketplace 1.0.0.20110607-2117(org.eclipse.m2e.发现1.0.0.20110607-2117)需要'bundle org.eclipse.equinox.p2.operations 0.0.0'但无法找到它无法满足依赖性:来自:m2e - Maven Integration for Eclipse 1.0.0.20110607-2117(org.eclipse) .m2e.feature.feature.group 1.0.0.20110607-2117)收件人:org.eclipse.m2e.discovery [1.0.0.20110607-2117]
我正在尝试将 CMake 用于 MIT JOS 操作系统项目 - http://repo.or.cz/mit-jos.git/tree或https://pdos.csail.mit.edu/6.828/2016/jos。混帐
这是目录结构
lab
- .bochsrc
- CODING
- GNUmakefile
- boot
- conf
- fs
- grade.sh
+ inc
- assert.h
- elf.h
- error.h
- kbdreg.h
- memlayout.h
- mmu.h
- stab.h
- stdarg.h
- stdio.h
- string.h
- types.h
- x86.h
- kern
- lib
- mergedep.pl
- user
- CMakeLists.txt
该CMakeLists.txt下lab的文件夹（即项目文件夹）的样子
cmake_minimum_required(VERSION 3.6)
project(lab)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES
boot/main.c

kern/console.h
kern/entrypgdir.c
kern/init.c
kern/kdebug.c …我使用BreakIterator.getWordInstance将中文文本拆分为单词.这是我的例子
import java.text.BreakIterator;
import java.util.Locale;
public class Sample {
public static void main(String[] args) {
String stringToExamine = "I like to eat apples. ???????";
//print each word in order
BreakIterator boundary = BreakIterator.getWordInstance(new Locale("zh", "CN"));
boundary.setText(stringToExamine);
printEachForward(boundary, stringToExamine);
}
public static void printEachForward(BreakIterator boundary, String source) {
int start = boundary.first();
for (int end = boundary.next(); end != BreakIterator.DONE; start = end, end = boundary.next()) {
System.out.println(start + ": " + source.substring(start, end));
}
}
}

我得到的输出是
