Description

Hi. I tried to install nv_peer_memory. I ran the following commands:

./build_module.sh
cd /tmp
tar xzf /tmp/nvidia-peer-memory_1.0.orig.tar.gz
cd nvidia-peer-memory-1.0
dpkg-buildpackage -us -uc
dpkg -i /tmp/nvidia-peer-memory_1.0-8_all.deb
dpkg -i /tmp/nvidia-peer-memory-dkms_1.0-8_all.deb

It failed when tried to install dkms deb. The full build log is:

$ dpkg -i /tmp/nvidia-peer-memory-dkms_1.0-8_all.deb
