what library used on arm gcc none eabi ?

1. Does arm-gcc-none-eabi and newlib is packed?

2. Why arm-gcc-none-eabi need glibc 2.14?

I have a problem when I use arm gcc none eabi cross compiler.

"version GLIBC_2.14 not found"

Then I install glibc 2.14 and add to LD_LIBRARY_PATH. It's perfect compile my code.

But I have not download newlib in my system.

I don't know what library is linked on arm-gcc-none-eabi.

Do I need add some option to use newlib when I Compile C code? Or default is linked to newlib.

This web site said arm-gcc-none-eabi is based on Free Software Foundation's (FSF) GNU Open source tools and newlib.
