请教JFFS2文件系统的移植问题
我接触LINUX的时间不长，最近仿照HOW TO USE MTD/JFFS2 UNDER µClinux制作jffs2文件系统遇到难题，郁闷许久，望哪位好心的高手指点迷津 内核选项配置完以后 make出错 如下：mkfs.jffs2.elf2flt: In function `create_target_filesystem':
/usr/local/uClinux-dist/user/mtd-utils/mkfs.jffs2.c:999: undefined reference to `__xpg_basename'
/usr/local/uClinux-dist/user/mtd-utils/mkfs.jffs2.c:1010: undefined reference to `__xpg_basename'
collect2: ld returned 1 exit status
make: *** Error 1
make: Leaving directory `/usr/local/uClinux-dist/user/mtd-utils'
make: *** Error 2
make: Leaving directory `/usr/local/uClinux-dist/user'
make: *** Error 1 你的编译器有问题？ 不好意思 我自己添加obj-$(CONFIG_MTD_S3C4510B) += s3c4510b.o
的时候把MTD后面的‘_’给写成‘—’了！ 我就说我之前自己编译了一个小程序烧进内核里还能运行来着呢！ 不过又出现了一个新错误：
drivers/mtd/mtdlink.o: In function `s3c4510b_copy_from':
/usr/local/NewuClinux-wsdist/uClinux-dist/linux-2.4.x/drivers/mtd/maps/s3c4510b.c:41: undefined reference to `memcpy_fromio'
drivers/mtd/mtdlink.o: In function `s3c4510b_copy_to':
/usr/local/NewuClinux-wsdist/uClinux-dist/linux-2.4.x/drivers/mtd/maps/s3c4510b.c:64: undefined reference to `memcpy_toio'
make: *** Error 1
make: Leaving directory `/usr/local/NewuClinux-wsdist/uClinux-dist/linux-2.4.x'
make: *** Error 1
不清楚是怎么回事？希望您能给指点一下 非常感谢！ +-------------------- Memory Technology Devices (MTD) --------------------+
难道是我内核配置的问题？以下是我的内核配置选项

看样子和存储系统有关系，似乎是内存？ 谢谢版主赐教
天啊 这下可完蛋了 再让我想几个月也想不出来啊
我要写一个字 惨！！！！！！！！！！！！！！！！！！！！ 我自己试着把出错误的那两个函数的名字改成memcpy就没有这个错误了！
不清楚是怎么回事！
但是又出现最开始第一个帖子里出现的那个错误了！郁闷死了！
没有人遇到这样类似的问题么？ 希望哪位大侠能共享一下这方面的经验！
