# 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.
