rtems build error

[nprakash at cedt.iisc.ernet.in]

 Hi
while I try to install the rtems4.6.5 for LEON3(SPARC), I get an error like
this, during make install,
_______________________________________________________________
`/home/prakash/rtems/rtems-4.6.5/build/sparc-rtems/c/leon3/libchip/network'

-----------------------------------------------------------------------------------------------------------------

the commands I used,
In build directory ( I created),
../configure --enable-cxx --target=sparc-rtems --enable-rtemsbsp=leon3
make RTEMS_BSP="leon3"
make install RTEMS_BSP="leon3"

I'm using FC4 and I could able to compile f.c with sparc-rtems-gcc without
error.

Any help is appreciated,
Prakash
