i wanted to add snmp to my nios2linux .

somebody said :

edit config.sub:

add "| nios2" in the "case $basic_machine in"

run:

./configure --host=nios2-linux --with-cc=nios2-linux-gcc --disable-shared -enable-static --with-endianness=little

compile and seems to work fine. (works under linux not cygwin)

but still have the same errors .

who can tell me how to do ?

thanks.
