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............... /home/bhushana/XC16X/run/xc16x-elf/lib/gcc/xc16x-elf/4.2.0/../../../../x c16x-elf/lib/xc16xl/libg.a(lib_a-makebuf.o): In function `___smakebuf': makebuf.c:(.text+0x1fb): undefined reference to `_isatty' makebuf.c:(.text+0x1fc): undefined reference to `_isatty' /home/bhushana/XC16X/run/xc16x-elf/lib/gcc/xc16x-elf/4.2.0/../../../../x c16x-elf/lib/xc16xl/libg.a(lib_a-sbrkr.o): In function `__sbrk_r': sbrkr.c:(.text+0x1d): undefined reference to `__sbrk' sbrkr.c:(.text+0x1e): undefined reference to `__sbrk' /home/bhushana/XC16X/run/xc16x-elf/lib/gcc/xc16x-elf/4.2.0/../../../../x c16x-elf/lib/xc16xl/libg.a(lib_a-closer.o): In function `__close_r': closer.c:(.text+0x1b): undefined reference to `__close' closer.c:(.text+0x1c): undefined reference to `__close' /home/bhushana/XC16X/run/xc16x-elf/lib/gcc/xc16x-elf/4.2.0/../../../../x c16x-elf/lib/xc16xl/libg.a(lib_a-fstatr.o): In function `__fstat_r': fstatr.c:(.text+0x25): undefined reference to `__fstat' fstatr.c:(.text+0x26): undefined reference to `__fstat' /home/bhushana/XC16X/run/xc16x-elf/lib/gcc/xc16x-elf/4.2.0/../../../../x c16x-elf/lib/xc16xl/libg.a(lib_a-lseekr.o): In function `__lseek_r': lseekr.c:(.text+0x2d): undefined reference to `__lseek' lseekr.c:(.text+0x2e): undefined reference to `__lseek' collect2: ld returned 1 exit status make: *** [Mathtest.out] Error 1 what went wrong ? Or the changes are incomplete and needs to do more? What should I need to do? Thanks in advance. Bhushan -- For unsubscribe information see http://sourceware.org/lists.html#faq
