Hello all
being a naturally lazy person i was wondering whether anyone knows of a
nice easy, step-by-step guide to modifying the dietlibc source so it
will compile on openbsd 3.7. the PORT file in dietlibc source describes
(not fully perhaps) waht to do:
- edit Makefile to detect the architecture
- create a directory for the architecture, and put a Makefile.add in
it. Look at the other Makefile.adds for guidance.
- provide start.S (the start code, look at glibc)
- provide unified.S (the unified syscall)
- provide syscalls.h (the syscall numbers, from asm/unistd.h)
- provide setjmp and longjmp
- edit include/setjmp.h
- pipe, clone and mmap often need special care
- edit include/sys/ioctl.h
- edit include/sys/ptrace.h
- edit include/asm/sigcontext.h
- edit include/sys/ucontext.h
- edit include/endian.h
- edit include/fcntl.h
- edit include/sys/mman.h
- edit include/sys/shm.h
- edit include/sys/stat.h
- edit include/errno.h
- edit syscalls.h
- edit include/termios.h
- edit diet.c to make it recognize the architecture and add proper
CFLAGS
- edit libcompat/syscall.S
i think if I tried myself it would take far too long to justify the outcome.
so are there anyone out there that wants to make it easier for me (and
everyone else)
thanks!
