Error : conflicting types for scandir and scandir64 while installing scratchbox 2 for LTP

Question

I followed the steps for installing scratch box 2;

git clone http://anongit.freedesktop.org/git/sbox2.git

./autogen.sh

cd sbox2

./configure --prefix=/opt/sb2

make install

But while installing, it shows conflicts for scandir and scandir64.

It will be grateful if someone could answer this. Thanks.
