You can take the patches for others applications as examples, in step13 of the guide.

The memory problem or others?Honored ContributorIt looks like run out of memory. The DE2 has only 8M sdram.
Try remove used file in ~/rootfs, remove unused devices in ~/download/rootfs_list, disable unused options in kernel, disable used options in busybox, use jffs2 on cfi mtd to store files or rootfs... all that help to reduce memory usage.Honored Contributor<div class='quotetop'>QUOTE </div>

If you want jffs2, read step7,8 in the buildroot guide. You have to edit drivers/mtd/maps/alters.c .
