Hello Please your's advice.I think such a problem with newlib...or with my gcc powerpc building process or with the makefile I attach a Zip example.
Please your remarks to the following procedure A. Under Cygwin - XP SP2 machine Getting the following tar files than extract / cerate the following subdirectories under C:\ cygwin\gnu_src\ < binutils-2.16.1> Pease your remarks to the building procedure 1. binutils-2.16.1 - ftp://mirror.switch.ch/mirror/gnu/binutils/ extract / create subdirectory C:\ cygwin\gnu_src\binutils-2.16.1 $./configure --target=powerpc ?eabi # maks # make install 2. gcc-4.0.2 - ftp://mirror.switch.ch/mirror/gnu/gcc/ extract / create subdirectory Create a spraete directory GccPowerpc create subdirectory C:\ cygwin\gnu_src\GccPowerpc - $../gcc ?4.0.2/configure --target=powerpc-eabi ?-enable ?languages=?c? # maks # make install 3. gdb-6.3. - ftp://mirror.switch.ch/mirror/gnu/gdb/ extract / create subdirectory C:\ cygwin\gnu_src\gdb-6.3- $./configure --target=powerpc ?eabi # maks # make install 4. newlib-1.13.0 . - http://sourceware.org/newlib/ extract / create subdirectory C:\ cygwin\gnu_src\gdb-6.3- $./configure --target=powerpc ?eabi # maks # make install I build a sample IDE - Eclipse - which demonstrated the problem only a main which contain sprintf command.see attach The following example caused to a following linker problem char buff[20]; sprintf (buff, "%s%d", "my_test",100); / usr/local/bin/../powerpc-eabi/lib/libc.a(vfprintf.o)(.text+0x18a0): In function `_vfprintf_r': ../../../.././newlib/libc/stdio/vfprintf.c:1065: undefined reference to `__umoddi3' /usr/local/bin/../powerpc-eabi/lib/libc.a(vfprintf.o)(.text+0x18bc):../../../.././newlib/libc/stdio/vfprintf.c:1066: undefined reference to `__udivdi3' /usr/local/bin/../powerpc-eabi/lib/libc.a(makebuf.o)(.text+0x12c): In function `__smakebuf': ../../../.././newlib/libc/stdio/makebuf.c:96: undefined reference to `isatty' /usr/local/bin/../powerpc-eabi/lib/libc.a(sbrkr.o)(.text+0x40): In function `_sbrk_r': ../../../.././newlib/libc/reent/sbrkr.c:60: undefined reference to `sbrk' /usr/local/bin/../powerpc-eabi/lib/libc.a(writer.o)(.text+0x48): In function `_write_r': ../../../.././newlib/libc/reent/writer.c:58: undefined reference to `write' /usr/local/bin/../powerpc-eabi/lib/libc.a(closer.o)(.text+0x40): In function `_close_r': ../../../.././newlib/libc/reent/closer.c:53: undefined reference to `close' /usr/local/bin/../powerpc-eabi/lib/libc.a(fstatr.o)(.text+0x44): In function `_fstat_r': ../../../.././newlib/libc/reent/fstatr.c:62: undefined reference to `fstat' /usr/local/bin/../powerpc-eabi/lib/libc.a(lseekr.o)(.text+0x48): In function `_lseek_r': ../../../.././newlib/libc/reent/lseekr.c:58: undefined reference to `lseek' /usr/local/bin/../powerpc-eabi/lib/libc.a(readr.o)(.text+0x48): In function `_read_r': ../../../.././newlib/libc/reent/readr.c:58: undefined reference to `read' make: *** [ADLAP.elf] Error 1 Only this example working well only without %d ?

This simple build project which generate the same errors as our operational project I'll appreciated if u can take a look on the Zip attachment open it, and see what can be wrong (TestEnvironment.zip) Maybe I miss something following the building the GCC for powerpc -Regarding to GCC-Powerpc Looking forwarded to your response asap.
