error with comlpling the sdk examples

I install ubuntu-9.04-desktop-i386,activate the driver I install CUDA TOOLKIT 2.3 and CUDA SDK 2.3 .When i “make” i got that:
undefined reference to `cudaBindTexture2D’
i have no idea how to deal with the problem.Is it because of the CUDA TOOLKIT and CUDA SDK version or the driver version? Does anyone install the same OS as mine?

Help please!
