Trying to build CUDA sdk in Ubunto 8.04 and got following error message:

What is Xi library? Please help…

Thanks,
Yanling

You need libXi-devel (or equivalent).

Thanks, I also installed libXmu. Wondering why CUDA need such library… :rolleyes:

Thanks! This is all that was missing for my compilation :) :thumbup:

CUDA doesn’t need such a library. Certain examples in the SDK have X-window GUIs and use these libs.
