arm_v5t_le toolchain can`t produce *.so

My Envirment: PlatForm: dm365 Toochain: arm_v5t_le app: lighttpd 1.4.22 I use following command to check toolchain " arm_v5t_le-gcc -fpic -shared test.c -o test.so ". It work well. I wanner compile lighttpd by arm_v5t_le. But it looks like can`t produce dynamic library(*.so). I use arm_v5t_le toolchain to compile minigui , and I get the same resault. Does anybody in the same situation? Does it can be resovled? How can I do?
