execvp: ln: Too many levels of symbolic links

[dkchalmers]

Hi,

I am trying to build the cuda roll on a new Rocks 7.0 installation.

Following the instructions, I download the cuda roll and run make

The make process dies with an error regarding symbolic links. build.log is attached

build.log

Any advice appreciated!

David

Did you run bootstrap.sh before make?

[dkchalmers]

Yes, we had run bootstrap.sh

Go to the top directory where you checked out CUDA roll source from github and do

pwd cd cuda/src/cuda-modules make clean make rpm

and show me the build log from the last command.

What is the top most directory where you start form ? Is this a simlink ?

[dkchalmers]

Here is the output. The prompt is misleading - the machine has centos 7 installed. Not ubuntu! The install directory is as specified in the instructions. It is a standard directory, not a symbolic link.

The top level /export is a symbolic link: export -> state/partition1

[nadyawilliams]

your errors are unlikely related to the roll itself. Check your file system layout. You may have different links that go in s circular way form /export to /state/partition1. What is df -h output?

[dkchalmers]

OK - I had three NFS mounted directories in the root directory (one mounted on /apps). I have unmounted these. The build now progresses further, but dies.

build.log

df -h now gives:

in cuda/src/nvidia-toolkit/version.mk set DISTRO as DISTRO = 8.0.61_375.26

and rerun make
