OS67 is a unix-like toy kernel, which comes with some user routines. (x86 based)
Platform: Linux
- gnu make
- nasm
- gcc
- binutils(ld, objcopy)
- mkfs
- bochs 2.6.7+
git clone https://github.com/SilverRainZ/OS67.git
cd OS67
make init # only for first time
make fs # build root file system and user routines, root privilege required
make # build kernel
make run # run with bochsint _fork();
int _exit();
int _wait();
int _pipe(int *fd);
int _read(int fd, char *addr, uint32_t n);

int _exec(char *path, char **argv);
int _fstat(int fd, struct stat *stat);
int _chdir(char *path);
int _dup(int fd);

int _close(int fd);- sh: a simple shell, support IO redirect and pipe
- ls: list files
- cat: read from stdin and send it to stdout
- mkdir: make directory
- rm: remove file
- ...
- add a new file in
usr/:touch usr/newroutine.c - add a new value to
UPROGSvariable inMakefileas follow:
- UPROGS = bin/cinit bin/sh bin/cat bin/ls bin/mkdir bin/rm
+ UPROGS = bin/cinit bin/sh bin/cat bin/ls bin/mkdir bin/rm bin/newroutine- in newroutine.c you can use these header files:
- usys.h: system call interfaces
- uio.h: basic input output functions
- string.h: basic string operate functions
make fs && make runthen you can run your user routine
Please paste the kernel logs in the issue.
Uncomment macro __LOG_ON as follow to enable logging of specific file:
- // #define __LOG_ON 1
+ #define __LOG_ON 1
