Q.- How to install rCUDA?

A.- Please refer to the Quick Start Guide and also to the User's Guide.

Q.- While trying to compile a source code, I'm getting errors such as “undefined reference to cuXxxxxxXxxxxx”, for instance.

A.- Please notice that, in order to use rCUDA, you should compile your code using the CUDA environment. That is, while compiling your application, rCUDA should not be used. You should compile your application as if it were going to be used with CUDA. Actually, it is good practice to check that your application works with CUDA (with a local GPU) before executing it with rCUDA.

Q.- I'm not able to run applications in rCUDA. I'm getting initialization errors.

A.- Please check whether all the prerequisites are met. Also, please check whether all the environment variables are properly set. Please refer to the Quick Start Guide and also to the User's Guide.

Q.- I'm getting the error “Error while loading shared libraries: libcudart.so.x.y: cannot open shared object file: No such file or directory.”

 A.- This is a run-time error, stating that your LD_LIBRARY_PATH is not pointing where the rCUDA library is.
