/usr/bin/ld: cannot find -<library>

Question

I am getting the error while running make-and-install.sh caffe . I have linked the /usr/local/cuda/libcudart.so to /usr/lib/libcudart.so and other files also

any kind of help will be appreciated.

Is there some problem with the libraries or the path .

Edit to add

ls -l /usr/lib/cu*

edit your post with the output of ls -l /usr/lib/cu*. Additionally, do file /usr/lib/libcudart.so (I'm guessing that your link (ln) is invalid.

^^^^^ Already done ^^^^^

As the broken link is confirmed, go to the /usr/lib/ directory and link (ln) again.

ln -s /usr/local/cuda/libcudart.so /usr/lib/libcudart.so

do this step for all desired libraries. As mentioned by @RobertCrovella, it appears there is some library knowledge required too, so add -L/usr/local/cuda/lib64.

Now, after typing all of that out, I would recommend not moving/linking any files, just add -L /usr/local/cuda -L/usr/local/cuda/lib64 which will find all of your cuda libraries.
