GccPowerpc eabi HowTo - probem with stido functions ( sprintf)

["moshed (sent by Nabble.com)" <lists at nabble dot com>]

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);

make: *** [ADLAP.elf] Error 1 


Only this example  working well only without %d ? It?s insignificant for me
sprintf (buff, "%s", "my_test");


powerpc-eabi-ld -Map ADLAP.map -o ADLAP.elf  appl.o main.o hardware.o init.o  -T lnk_mpc555_rom.lcf -L c:/555/libumas -lumas -lm -lc
powerpc-eabi-objcopy -O srec ADLAP.elf ADLAP.rom
powerpc-eabi-objdump -Sx ADLAP.elf > ADLAP.dump

what can be the problam ? 


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.
