cmake fails with v2.2 on Linux Mint 17.2 (i.e. Ubuntu 14.04)

[wxChap]

Hi,

I've tried building cudpp both from the zip file for 2.2 as well as the latest master branch, but both fail, complaining with a missing file from the source tree:

#### Begin ####

$ cmake .

#### End ####

The card is a new-ish GeForce 630, and can run simple CUDA programs fine. The directory ext/moderngpu is empty. Thanks for any help.

When you fetch CUDPP from git, make sure to get the submodules. I usually do this with

git clone --recursive https://github.com/cudpp/cudpp.git

Anyway, your ext/moderngpu and ext/cub directories need to be filled with the moderngpu and cub distributions, respectively.

If you have already cloned CUDPP, then from the CUDPP home directory, you need to:

    git submodule init

    git submodule update

But Sir,

I have checked with --recursive and by doing init and then update. But I am getting the following error:

rintu@rintu:~/Downloads/mars_lab$ git clone --recursive https://github.com/cudpp/cudpp.git

Can you please check.

This appears to be a problem with your connection to github and has nothing to do with CUDPP. Appended is my trace from running the same command.
