I try to give more details.

In order to create blocks using the standard way(cmake/make/install) with Cuda,I've modified the CMakeList in /lib as shown before. My block is created using gr_modtool and the language is c++.

The fact is that "make test" works well,while in GnuRadio interface give me the following error AttributeError: 'module' object has no attribute 'helloFunc_ff'.

Everything worked well before the addition of CUDA code(so it's not the problem experienced by other users)

Thanks,

Have you checked the library itself to see if the block exists there? 'nm -C lib<project name>.so | grep helloBlock' should tell you if it was properly built into your library.
