Installation failed : make pkg.debian.build

[Skylixia]

When trying to make the installation I get errors at the step with "make pkg.debian.build" :

make pkg.debian.build
make -C pkg debian.build BUILDDIR=/nccl/build

How to solve this ?

[AddyLaddy]

You need to install the Debian package build helpers;

sudo apt-get install fakeroot devscripts debhelper

@Skylixia did you install prerequisites ? The steps are on the NCCL head page :

$ # Install tools to create debian packages
$ sudo apt install build-essential devscripts debhelper fakeroot
$ # Build NCCL deb package
$ make pkg.debian.build
$ ls build/pkg/deb/
