shifting syscalls to libgloss

[Bhushan Attarde]

Hi,

 

We are working on GNU based tool chain for infineon xc16x
microcontroller.

Currently the syscalls are in /newlib/libc/sys and we are trying to
shift them to /libgloss.

 

So after some google search we found some way to do that.......

And done some changes which are as follows:

 

 

 *  newlib-1.15.0/configure.in    : removed target-libgloss from
noconfigdirs for xc16x-*-*

 

 *  configure  : regenrate

 *  newlib-1.15.0/newlib/configure.host: : set sys_dir to empty for
xc16x-*-*. And set syscall_dir to xc16x

 *  configure  : regenerate 

 *  newlib/libc/sys/xc16x/ configure.in : removed

 *  newlib/libc/sys/xc16x/ configure : removed

 

 *  newlib/libc/sys/xc16x/ crt0.s : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ close.s : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ create.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ getchar1.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ isatty.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ lseek.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ mem-layout : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ misc.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ open.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ putchar.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ puts.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ read.c : moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ sbrk.c: moved to libgloss/xc16x

 *  newlib/libc/sys/xc16x/ syscalls.c : moved to libgloss/xc16x

*  newlib/libc/sys/xc16x/ trap-handle.c : moved to libgloss/xc16x

*  newlib/libc/sys/xc16x/ write.c : moved to libgloss/xc16x

* newlib/libc/sys/xc16x : reomoved

 

*  libgloss/xc16x/configure.in : new

*  libgloss/xc16x/configure : regenerate

 

With these changes I built the tool chain, it got built without any
error.

But when I tried to compile one of our sample program I got the
following errors...............

what went wrong ? Or the changes are incomplete and needs to do more?

What should I need to do?

 

Thanks in advance.
