upgrading to cuda 2.2.1 seems like it isn't working


I would like to check if i did the correct instalation , in order to upgrade cuda to 2.2.1 version, i did this:

  1. downloaded cuda 2.2.1 (filename: cudasdk_2.21_linux.run) from here http://forums.nvidia.com/index.php?showtopic=98589

  2. ran these comands:

mv /usr/local/cuda /usr/local/cuda-old

mkdir /usr/local/cuda



cd /usr/local/cuda


when i check the cuda version after installation i see that it still has the 2.2 version:

master cuda # nvcc --version

nvcc: NVIDIA (R) Cuda compiler driver

Cuda compilation tools, release 2.2, V0.2.1221

master cuda #

note the : Cuda compilation tools, release 2.2, V0.2.1221

Correct me if i am wrong, but you have to first install cudatoolkit (which is only 2.2 version), and then overwrite /usr/local/cuda with cudasdk 2.2.1 , and then compile, right? Well this procedure doesn’t confirms cuda 2.2.1 installation. What is wrong?

Thanks in advance

there’s no 2.2.1 toolkit, only a 2.2.1 sample pack (the SDK)
