Git checkout fails

[Jan]

Hi,

I am trying to install CUDPP on linux. When checking out the git repository using git clone --recursive https://github.com/cudpp/cudpp.git, I get the error message

Same when omitting the --recursive option and instead issuing git submodule init/update.

Any help is appreciated.

Best,
Jan

This is a CUB issue based on Duane cleaning up CUB's history:

https://github.com/NVlabs/cub/issues/94

It would be helpful if you figured out what the right submodule reference is (manually) and tell us and we'll then put it back into the repo?

Hi John,

thanks a lot for your quick reply. Unfortunately, I am fairly new to git and therefore feel unable to carry out/properly understand what you suggested. I have now simply downloaded the sources from the 2.2 release, which does the trick for me for the moment.

However, it would be nice if somebody with more experience/knowlegde in git could perform what you suggested.

Best,
Jan
