Fail to compile in Cuda 4.0 though compiled successfully in cuda 3.2

Hi all,

I am working on a cluster that used to have cuda 3.2 and my code used to compile successfully. Recently, they upgraded to cuda 4.0 and since then the compilation is resulting in claiming that some files don’t exist though they do exist although I haven’t changed anything in my code.
For instance: kernels/ error: sparse_formats.h: No such file or directory

I tried to run another simple code and it worked properly. Anybody has any ideas on differences or problems with cuda 4.0?

Any help is highly appreciated.
