linking nsdl lib failed with unsolved symbol
Hi, I try to link nsdl lib in my offline development environment. It fails with errors like:
error
nanoservice_client_1_12\sn_grs.c:(.text+0x46c): undefined reference to `__aeabi_memclr4'
here is my building command (unrelated object file removed):

arm-none-eabi/bin/ld.exe: final link failed: Bad value collect2.exe: error: ld returned 1 exit status
Could you help me find what is wrong here?
Thanks!

It turns out that the online IDE probably use armcc toolchain, which has optimized version for memcpy, memmove and memclr etcs.(http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka3934.html) But they are not available in arm-gcc 4.8. It can be solved by updating to latest newlib (https://sourceware.org/newlib/), which contains such symbols (aeabi_memcpy, aeabi_memmove etc.) or implementing these functions by ourselves.
