Gary thanks for the example and it's Howto. I now get this error:

arm-elf-gcc -c -mthumb-interwork -mcpu=arm7tdmi -mno-short-load-words -Wall

I think I figured out what's going on/ It compiles
version.c but I doubt it's being put into the lib
file. When I add


to the arm-elf-gcc line it compiles.
