I apologize for the strange-ness of the email but we've been struggling with this problem for several days. First, I have GNU Radio 3.7.5.1 installed on three different Laptops each running 64-bit Ubuntu. GNURadio was installed using the 'apt-get' install call for gnuradio with no other modifications. The steps below will produce this exact problem on every machine we have tried it on. Step 1. Pick any GNU Radio Tutorial such as the 'square2_ff' Tutorial. Follow all the steps exactly as indicated to create the basic block. Compile and install the block into GNURadio following the steps in the Tutorial. Run the Block in GNURadio. The Block should work in GNURadio exactly as indicated in the Tutorial. Great Tutorial by the way! Step 2. Now, completely exit GNURadio. Open the 'square2_ff_impl.cc' file (or whatever your implementation file is) and add (any) one of the C++ API Class Headers such as: #include *gnuradio/filter/fir_filter_fff.h* http://gnuradio.org/doc/doxygen/fir__filter__fff_8h_source.html Next, in the constructor for square2_ff_impl add a single line to instantiate a filter object such as: gr::filter::fir_filter_fff::sptr filter(gr::filter::fir_filter_fff::make(1,m_taps)); Make sure the 'm_taps' vector does in fact hold values but don't do anything else here. Just declare a variable of the C++ API Class you picked. Do not modify any other files than the .cc file. Step 3. Following this, compile the Block code and install the Block into GNURadio again following the exact same steps from the Tutorial as before. The Test Steps on my machine do not indicate any errors here, which is adding to my confusions. Step 4. Open GNURadio and try running the 'square2_ff' (or whatever yours is called) Block again. Now, with every machine I've tried this on, you will get the error: AttributeError:'module' object has no attribute 'square2_ff' Following this, exit GNURadio completely. Step 5. Open the source module 'square2_ff_impl.cc' file again and comment out only the line where you instantiated the 'filter' object. Leave the #include for 'fir_filter_fff.h' alone. Recompile and reinstall the Block back into GNURadio following the Tutorial steps as before. Don't modify anything else other than the .cc file. Step 6. Open GNURadio again and try the square2_ff block again. This time it works exactly as it should with no errors. For some reason, the C++ OOT Blocks will not run inside GNU Radio if I try to use any of the C++ API Classes in the implementation code. I've tried everything I can think to move the declarations/headers around but nothing works. Granted, I have not tried every single API Class but I've tried enough to know it doesn't work. I do not touch any of the swig or python files or XML files. The only file I touch is the implementation file and this is enough to cause this error. What am I doing wrong here? This problem is all over the internet but none of the solutions offered seem to work on any machine I try them on?? Any help on this would be greatly appreciated.

Yep, that tells you it right there. You are not linking against the ITPP
library. Here's the change you need to make to your lib/CMakeLists.txt file:
add_library(gnuradio-wsi SHARED ${wsi_sources})
-target_link_libraries(gnuradio-wsi ${Boost_LIBRARIES}
${GNURADIO_ALL_LIBRARIES})
+target_link_libraries(gnuradio-wsi ${Boost_LIBRARIES} ${wsi_libs})
set_target_properties(gnuradio-wsi PROPERTIES DEFINE_SYMBOL
gnuradio_wsi_EXPORTS)
You've created a wsi_libs variable already, but never added this to the
target_link_libraries call. So when trying to open the shared library and
make ITPP calls, you couldn't, which was causing the import to fail. Notice
all of the extra libraries it links against when you make this change

I was hoping that the gdb call would tell us of the failure going on in
inside the module while it was trying to import it, but looks like that's
opaque here. Oh well.
Also, just as an aside, your git needs a bit of work. You've added the
build directory, which you should never do, as well as all of your
temporary emacs files (the files ending in ~). And for some reason, your
root directory is Documents with gr-wsi underneath. Just some tips to make
it easier

[Discuss-gnuradio] AttributeError: 'module' object has no attribute 'block_name'
Hello all,
I've just created a block called sliding_fft. The _impl.h file looks
like:
#include gnuradio/fft/fft.h
namespace gr {
namespace lte_dl_rx {
class sliding_fft_impl : public sliding_fft
{
private:
fft::fft_complex *d_fft;
uint d_fft_size;
uint count;
public:
sliding_fft_impl(uint fft_size);
~sliding_fft_impl();
// Where all the action really happens
int work(int noutput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items);
};
} // namespace lte_dl_rx
} // namespace gr
and the _impl.cc looks like:
/*
* The private constructor
*/
sliding_fft_impl::sliding_fft_impl(uint fft_size)
: gr::sync_block(sliding_fft,
gr::io_signature::make(1, 1, sizeof(gr_complex)),
gr::io_signature::make(1, 1, fft_size*sizeof(gr_complex))),
d_fft_size(fft_size),
count(1)
{
d_fft = new fft::fft_complex (fft_size, 1, 1);
set_history(fft_size);
}
There is no attribute problem till I don't use the d_fft = new
fft::fft_complex (fft_size, 1, 1); line in the constructor!
After working a lot, I got the attribute error in grc is due to this line!
Please help me why this is happening ?
Thank you kindly,
Mostafa

Re: [Discuss-gnuradio] AttributeError: 'module' object has no attribute 'block_name'
Hi,
I have individuated the error and we are near the solution, thanks to all.
I just remember the error that appear when I try to run a simulation of my
new block power:
Traceback (most recent call last):
File /home/simone/Scrivania/top_block.py, line 228, in module
tb = top_block()
File /home/simone/Scrivania/top_block.py, line 71, in __init__
self.t1_power_0 = t1.power(0.001, 0.5)
AttributeError: 'module' object has no attribute 'power'
I tried my block just eliminating the use of the class function
gr::uhd::usrp_source and it works.
So, the error is in the way in which I define and call a new USRP source
block.
/*** INSTRUCTION
/
This is my creation of the new UHD object in the _impl.cc file of my new
written block
::uhd::device_addr_t addr;
gr::uhd::usrp_source::sptr my_usrp_source =
gr::uhd::usrp_source::make(addr, ::uhd::stream_args_t(fc32));
and then I use this function
DB_gain = (float) my_usrp_source-get_gain(0);
/**/
I have some questions:
consider the flowgraph attached in this mail,
first of all, I'm using an usrp (UHD: USRP SOURCE block) with a fixed ip
address (addr=192.168.10.2), and I set sudo ifconfig eth0 192.168.10.1
and get addr 192.168.10.2 to setup the device.
In the same flowgraph, in my created block (my _impl.cc) now I'm creating
another USRP source block and I don't understand which address I need to
use to set correctly the make function (see instruction above) for
modifying parameters of the same USRP that is working, the USRP with
address 192.168.10.2.
In my code I set addr=192.168.10.2
Second, this definition:
gr::uhd::usrp_source::sptr my_usrp_source =
gr::uhd::usrp_source::make(addr, ::uhd::stream_args_t(fc32));
is sufficient to put it into the general work and no other places to use
this class??? The compilare does not advice me that there is an error, but
my definition for class usage is not clear and wrong and then I get error
in simulation...
Anyway, is well appreciated if someone can show me the correct way to
define and use function of other classes into a new created block!

Yeah, I figured there were two arguments. I just put them as x and y.
One thing that can happen here is if there's a declared function in the
public and/or private header that's not implemented in the .cc file. You
might have something like that going on, such as not having or deleting
the
destructor. Using gr_modtool should protect you from things like this,
and
testing it out on my end here worked fine. Just double-check your work to
make sure you didn't remove anything you shouldn't have.

We've been seeing this issue from a few people recently. I can't
duplicate
the problem. I just did exactly what you did above, though the work
function doesn't actually do anything.
Are you potentially adding some interface setter or getter to the class
and
not putting it in all the right places (pure virtual in the public
header,
then again in the private header, and implemented in the source file)?
Have you added QA code? In qa_power_control.py, just add a line to the
test
function to create the PWagc.power_control(x,y) and see if it works
there.

Re: [Discuss-gnuradio] AttributeError: 'module' object has no attribute
Hi Mike, my first guess if making from scratch didn't help: maybe your module's name is conflicting with an existing module, or there are remnants of a former installation lying around for some reasons. You could try uninstalling your module via make uninstall, and then running a python trying to import yourmodule; if that doesn't fail, we know there's a conflict. Another popular source for errors are spaces and special characters in paths; but since you didn't move your module, this is not very likely the cause. Btw: what's your GNU Radio version (gnuradio-config-info -v)? Greetings, Marcus On 27.07.2014 18:17, Mike wrote: I followed the tutorial to generate a module and all was well.

Thanks Martin, Now I'm able to add running blocks.

If I add a C++ block with gr_modtool add -t general square_ff then the error disappears. What should I do if I want to add a block written only in Python?

EVT_DATA_EVENT = wx.PyEventBinder (myDATA_EVENT, 0) AttributeError: 'module' object has no attribute 'PyEventBinder' any ideas? i've looked everywhere and have even upgraded to gcc-3.4.3 and re-compiled everything. cheers, = mj - m0mik hotstudent.com [are you hot enough?! __ Do you Yahoo!?
