- https://sourceware.org/newlib/ftp/
- get newlib source code
```
wget ftp://sourceware.org/pub/newlib/newlib-4.1.0.tar.gz
tar xzf newlib-4.1.0.tar.gz
cd newlib-4.1.0/
./configure --target arm-none-eabi --disable-newlib-supplied-syscalls
make
cd ..
```

```
wget ftp://sourceware.org/pub/newlib/newlib-4.1.0.tar.gz
tar xzf newlib-4.1.0.tar.gz
cd newlib-4.1.0/
./configure --target aarch64-none-elf --disable-newlib-supplied-syscalls
make
cd ..
```

- compile the program with the Glib
```
arm-none-eabi-gcc -mcpu=cortex-a8 -I $AARCH32_CROSS_PATH/arm-none-eabi/include -c -o test.o test.c
arm-none-eabi-as -mcpu=cortex-a8  -o startup.o startup.s
arm-none-eabi-gcc -mcpu=cortex-a8 -I $AARCH32_CROSS_PATH/arm-none-eabi/include -c -o syscalls.o syscalls.c

arm-none-eabi-objcopy -O binary test test.bin
qemu-system-arm -M realview-pb-a8 -serial stdio -kernel test.bin
```

- compile the program with the Newlib
```
