从零开始在 StarryOS 中运行 Dora
第二节：运行 dora -h
接着上一节, 我们已经搭建好了StarryOS的开发环境, 现在开始运行StarryOS系统.
执行如下命令
$ make clean && make A=apps/monolithic_userboot LOG=error ARCH=x86_64 FEATURES=img run
先清空make缓存, 再启动StarryOS
启动后将出现如下图所示
在当前的shell中输入/dora -h命令,如果不出意外的话会有一个错误提示.
/dora: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory
说明系统缺少动态库libgcc_s.so.1文件. 这个动态库文件我们可以通过x86_64架构下的ubuntu 22.04系统中的/lib/x86_64-linux-gnu/目录下去寻找缺少的动态库文件. 并把它复制到当前的磁盘的/lib目录下。
注意
每次补全一个缺少的动态库之后需要清空
make缓存之后, 再构建运行系统才可以生效。如此反复的看到提示缺少哪个的动态库，就复制过来。当然你也可以根据下面的表格对应的架构列出来的动态库文件，一次性的补全。
整理各个架构下所需要的动态库文件
x86_64:/lib/x86_64-linux-gnu/aarch64:/lib/aarch64-linux-gnu/riscv64:/lib/risscv64-linux-gnu/
| 动态库文件 | x86_64 | aarch64 | riscv64 |
|---|---|---|---|
libgcc_s.so.1 | √ | √ | √ |
libm.so.6 | √ | √ | √ |
ld-linux-aarch64.so.1 | √ | ||
libdl.so.2 | √ | ||
librt.so.1 | √ | ||
libc.so.6 | √ | √ | |
libpthread.so.0 | √ | ||
ld-linux-riscv64-lp64d.so.1 | √ | ||
libz.so.1 | √ |
把缺少的动态库全部补全之后, 运行/dora -h的效果如下:
