Tensorflow C++ API example line ending?

I have a problem running the standard C++ API example: https://www.tensorflow.org/api_guides/cc/guide

I created all the files and directories. Bazel then throws an error after being started.

My system is running Debian. It looks like there is an issue with the line ending, but I could not really find anything. Shouldn't work the examples under Linux systems by default?

Or did I misconfigure bazel somehow?

Solution

After running dos2unix on all files in the tensorflow directory, compilation works. I think this is really weird. Shouldn't tf be supposed to run out of the box in a Unix system? Anyway, refer How can I run dos2unix on an entire directory? to run dos2unix recursively.
