I just wanted to test NPP for the first time. Therefore I modified my library (currently only IPP (library) and OpenCV (library and test application) included as external dependencies). To add NPP I added all CUDA dependencies (Cuda 2.3) and npp. When i link the library against libnpp64.so i get a segfault right away when i call the test application. I do not include any headers, nor do i call npp functions. When calling npp functions the behaviour is of course the same.
OS: Ubuntu 9.10
(GeForce GTX 280)
The readme file of NPP says that the library to link agains is common/lib/libnpp-mt.lib. Well this is true for Windows but for Linux this should be libnpp64.so?
Debugging with gdb does not really help:

Thanks for any hints so that i can play around with NPP.
