+# 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](http://117.143.63.254:9012/www/rt-smart/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
|
|
|
+
|
|
|
+```python
|
|
|
+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：
|
|
|
+
|
|
|
+```bash
|
|
|
+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
|
|
|
+
|
|
|
+```bash
|
|
|
+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：
|
|
|
+
|
|
|
+```bash
|
|
|
+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)
|
|
|
+
|
|
|
+```bash
|
|
|
+~/workspace/rt-thread/bsp/x86$ ./run.sh
|
|
|
+xorriso 1.4.8 : RockRidge filesystem manipulator, libburnia project.

|
|
|
+Writing to 'stdio:bootable.iso' completed successfully.
