Problem with HW Select

After menuconfig I have done this :

$ ~/uclinux-dist$ make vendor_hwselect sysptf=/home/samratv/desktop/de2_nios_device_led/hw/system_0.ptf

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- -C vendors vendor_hwselect

make[1]: Entering directory `/home/samratv/uClinux-dist/vendors'

make -C /home/samratv/uClinux-dist/vendors/Altera/nios2nommu/. dir_v=/home/samratv/uClinux-dist/vendors/Altera/nios2nommu/. -f /home/samratv/uClinux-dist/vendors/vendors-common.mak vendor_hwselect

make[2]: Entering directory `/home/samratv/uClinux-dist/vendors/Altera/nios2nommu'

make[2]: *** No rule to make target `vendor_hwselect'. Stop.

make[2]: Leaving directory `/home/samratv/uClinux-dist/vendors/Altera/nios2nommu'

make[1]: *** [vendor_hwselect] Error 2

make[1]: Leaving directory `/home/samratv/uClinux-dist/vendors'

make: *** [vendor_hwselect] Error 2

why did i get those errors ?

i have specified the path correctly.

Please help.
