Dear Sir,
Please your advice.I think
such a problem with newlib...or with my gcc powerpc building process.or with the
makefile see attach example ( also in the Zip) .
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>
<gcc-4.0.2> <gdb-6.3> <newlib-1.13.0>
Pease your remarks to the
building procedure
1. binutils-2.16.1 -
ftp://mirror.switch.ch/mirror/gnu/binutils/ extract / create subdirectoryC:\ 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
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 ?
I build a sample IDE -
Eclipse - which demonstrated the problem only a main which contain sprintf
command.
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.
