I am using the emWin516 library with an NXP LPC18xx. I'm successfully compiling with IAR embedded workbench by linking to emWin_516_IAR640_M3_LE.a

My trouble is I now need to change the compiler from IAR to instead use GNU Tools for ARM (https://launchpad.net/gcc-arm-embedded).

The emWin library folder has 4 subfolders:
EmbeddedWorkbench_6
LPCXpresso_4
uVision_4
VisualStudio_2010

I expected to find a sub folder for GNU tools for ARM, but maybe I am misunderstanding something.

Instead I attempted to link to the embeddedworkbench_6 folder but I get linker errors for the following:
__aeabi_memcpy4
__aeabi_memclr
__aeabi_memmove
__aeabi_memcpy
__aeabi_memset

Any ideas? It's possible I could just be doing something really stupid since this is the first time using GNU tools...
