Problem in creating a new block in GRC


I am trying to create a new block in GRC. I have added all the 3 files
.h and .i into /gnuradio-3.3.0/gnuradio-core/src/lib/gengen and did the
changes in and added a xml file in
and did the changes in

After this i did the ./bootstrap and ./configure. When I started make,
gave me following error

libtool: link: ( cd “.libs” && rm -f “” && ln -s “…/” “” )
make[6]: Leaving directory
/home/asm/gnuradio-3.3.0/gnuradio-core/src/lib/general' make[5]: Leaving directory/home/asm/gnuradio-3.3.0/gnuradio-core/src/lib/general’

Can anyone help me in this.
