what is this problem?

Hi, everyone, I met some problems when I compiled the uClinux-dist-20060803,

make menuconfig

make vendor_hwselect SYSPTF=nios_0.ptf

make romfs(errors, ignored)

make

request.o(.text+0x994): In function `process_header_end':

/home/liaoliang/uClinux-dist/user/boa/src/request.c:560: warning: the use of `tmpnam' is dangerous,

better use `mkstemp'

Can't run cmd gzip -f -9 >> boa

collect2: ld returned 4 exit status

make[4]: *** [boa] Error 1

make[4]: Leaving directory `/home/liaoliang/uClinux-dist/user/boa/src'

I searched this problem, some guys said this was a compile error, could be ignored, but when I downloaded the zImage to the DE2 board, there was kernel panic.
