[En-Nut-Discussion] Beginners question

[Jan Falkenhain]

Hi,
Just starting with the AVR radio example, I had the following problem:
As I want to connect with hard code IP in local network, I take out the
NutDhcpConfig(). When I delete the second call of this function, compiling
with WinAVR, I get the following errors of undef. ref. to an amount of
functions. example:

avr-gcc mnut03_mod3.o -mmcu=atmega128
-Wl,--defsym=main=0,-Map=mnut03_mod3.map,--cref -L../../lib/gcc/atmega128
../../lib/gcc/atmega128/nutinit.o -lnutpro -lnutos -lnutdev -lnutnet -lnutcrt
-o mnut03_mod3.elf
../../lib/gcc/atmega128\libnutdev.a(lanc111.o)(.text+0x392): In function
`NicInterrupt':
: undefined reference to `NutEventPostAsync'

Why is that and
where can the sourcecode of the library functions be found?
