Re: [Discuss-gnuradio] CMake and CUDA

[marco Ribero]

Thank you very much for your reply.
I've launched your command over the  library build/lib/libgnuradio-hhh.so (is the unique in this folder), generated using cmake/make/sudo..
Entries seems ok.

Output of nm -C | grep over the basic version(without CUDA):
http://pastebin.com/index/QJSvXLpz

Output of nm -C | grep over the version with CUDA(a simple memcpy,the block works perfectly with make test)
http://pastebin.com/index/9BXvv6X3

They seems equal(except addresses)

The name of the project is hhh(gr-hhh),and the block is mod(mod_ff), sorry for names..

This is the log given by gnuradio:

Traceback (most recent call last):

  File "/home/marco/Scrivania/gnuradio/top_block.py", line 203, in <module>

    tb = top_block()

  File "/home/marco/Scrivania/gnuradio/top_block.py", line 162, in __init__

    self.hhh_mod_ff_0 = hhh.mod_ff()

AttributeError: 'module' object has no attribute 'mod_ff'

Reattached kernel driver

Thanks for your effort,

marco

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,

Marco

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.
