Return to PORTING CVS log

Up to [DVB] / dietlibc

add a few more auxvec elf #defines
make errno __thread

To port the diet libc to a new architecture, you need to:

  - 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/sys/tls.h
  - edit include/errno.h
  - edit syscalls.h
  - edit include/termios.h
  - edit lib/__get_cur_tcb.c
  - edit diet.c to make it recognize the architecture and add proper
    CFLAGS
  - edit libcompat/syscall.S
  - edit include/fenv.h

(I may have missed a few)
