RT-Thread for x86

这是一份基础的RT-Thread针对x86的版本、移植，主要是能够在qemu中执行。以下说明主要针对Linux的环境，如果是Windows环境，请使用Env工具，同时请自行处理生成iso的方法。

编译

编译RT-Thread for x86版本，还需要一份支持newlib的工具链，可以通过以下地址获得：

*i386-unknown-elf_for_x86_64-pc-linux-gnu_latest.tar.bz2

下载后解压，然后在rtconfig.py中配置其中的EXEC_PATH变量

if  CROSS_TOOL == 'gcc':
    PLATFORM    = 'gcc'
    EXEC_PATH   = os.getenv('RTT_EXEC_PATH') or 'E:/Program Files/CodeSourcery/Sourcery_CodeBench_Lite_for_IA32_ELF/bin'

然后在x86 bsp目录下执行scons命令来编译：

scons

配置

RT-Thread for x86的版本也支持menuconfig的配置方式，在Linux下可以使用scons --menuconfig的方式进行配置。

因为menuconfig是一份字符界面的配置（Kconfig），在ubuntu下需要安装ncurses5的库

sudo apt install libncurses5-dev

运行

在ubuntu下运行，请确保你安装了qemu-system-i386，grub 以及 xorriso软件包：

sudo apt install qemu-system-x86 grub-common xorriso

然后执行./run.sh命令可以使用qemu来模拟执行(它也会生成可启动的iso文件)

~/workspace/rt-thread/bsp/x86$ ./run.sh

在qemu下可以按Ctrl-A + X退出qemu。
