How to build uclinux to DE2 board ,please help!

Thanks for your reply.

When I config my kernel of "net" part(module), a problem puzzled me ,that is ..

when I choose Networking options ----------->packet socket:mapped io ,an error occured : net/packet/af_packet.c file in line 1700.(I checked it ) ,a function ""vm_insert_page()"" does not declare

it is in the function of packet_mmap();but when I disable(leave it blank ) this ooption ,make successfully.

while configing kernel ,I refer to another book about arm linux kernel -compile .so I want to know the reason of this different ,what's this option for ?

Thanks in advance. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
