I tried installing the droid cam on my fedora 19 (64 bit) .

Link to the droid cam application is here

and whenever I try to install it , the Makefile which is as follows is invoked

obj-m := v4l2loopback-dc.o

all:
        make -C /lib/modules/`uname -r`/build M=`pwd`

test:
        gcc test.c -o test

clean:
        make -C /lib/modules/`uname -r`/build M=`pwd` clean

insmod:
        sudo insmod v4l2loopback-dc.ko width=320 height=240

rmmod:
        sudo rmmod v4l2loopback-dc.ko

and here is the error

 -- INSTALL:  Webcam parameters: '320' and '240'
 -- INSTALL:  Building v4l2loopback-dc.ko
make -C /lib/modules/`uname -r`/build M=`pwd`
make: *** /lib/modules/3.9.5-301.fc19.x86_64/build: No such file or directory.  Stop.
make: *** [all] Error 2
 -- INSTALL:  v4l2loopback-dc.ko not built.. Failure

build happens to be a symbolic link.I was wondering what exactly is the makefile trying to and why is it failing?
