[Discuss-gnuradio] Bugs gr-ldpc module‏

[Luiz Silva]

Hello,

Well, I installed the gr-ldpc module using pybombs in Gnuradio v3.7.6.1, and it no error occurred during the installation. I opened the Gnuradio and searched the module in the module list, and it was there, but when I tried to add the block: ldpc_encoder_bb to my project, the entire project in the flow graph disappeared, like when there is an erro in the .xml file of the block.

So, because of that, I tried install the module using OOT method. But I got the same results.

The installation by OOT method occurred well, it was presented only some warnings during cmake process (file: log_cmake.txt).

After that, I tried to open the example 1 of this module, it looked like the module would work fine, but after I configured the project to use my alist file ( alist file example from: http://www.inference.phy.cam.ac.uk/mackay/codes/alist.html) and executed the flow graph, the gnuradio showed me the some errors. (File: log_gnuradio.txt)

I don't know what can be causing these errors, maybe some library or module is missing.

Do you have some ideia what can be?

Thanks.
