[Discuss-gnuradio] Packet based system

[Vamsi Krishna Adsumilli]

Hi,

Is there a way to existing block which sends out data only when packet arrives 
but keeps sending out nothing until then? I expected “PDU to tagged stream” 
block to work that way, but it seems like that block waits for input to fill to 
start sending out stream.

I would like to build something like a packet based system where packet occurs 
only at certain times.

Thanks in advance.

Hi,
I tried the following solution, but it didn't work for me.

I have tried the same on another macOS system with similar results.I have even 
installing gnuradio-devel macport, which gave the same error.

There is a python error twice (once during initial GNURadio startup and later

Could you please let me know how to resolve the issue?

[Discuss-gnuradio] Rational number for Interpolation factor

[vamsi krishna]

Hi,
Is there a way to get rational number as interpolation (or decimation) factor 
rather than just a integer?I have gone through the documentation and found this,
gr_sync_interpolator::gr_sync_interpolator (const std::string ,            
                                gr_io_signature_sptr input_signature,           
                                  gr_io_signature_sptr output_signature,        
                                    unsigned interpolation)
Here we have interpolation factor to be unsigned which means it is a integer. I 
was wondering if we can have rational number (i.e, for example 2 inputs produce 
3 outputs).

Hi Marcus,
RAM was the issue. It worked like charm once I increased the RAM size.
Thank you.

 This is almost certainly due to GCC running out of memory during compilation 
of (rather large) SWIG-generated code.  Add more memory to
   your VM, and/or add swap space.

[Discuss-gnuradio] Linking .so files to OOT module

[vamsi krishna]

Hello everyone,
I'm trying to create a source and sink block which will connect to a database 
to fetch and drop data. The interface to the database is created using shared 
libraries (.so files) that were defined by someone else, not us. I have 
included the header file, which contains all the interfaces, inside the include 
folder of the module.
I tried looking for possible solutions and many times it was mentioned to use 
"target_link_libraries" in CMakeLists.txt file. Could anyone let me know how 
and where it should be included?
Note : The code gets compiled and placed into respective folders alright, but 
there is this exception after executing on gnuradio-companion.
Traceback (most recent call last):
File "/xxx/x/.py", line 754, in 
tb = ()
File "/xxx/x/.py", line 617, in __init__
self._src_0 = x._src("127.0.0.1", 1234, "Username", "password")
AttributeError: 'module' object has no attribute '_src'
