Block key "isdbt_bit_deinterleaver" not found

[ShiX10]

Hello,I am a student who recently started using GNUradio on MacOS(macOS High Sierra 10.13.6). I installed GNUradio(3.7.13.4) on my computer and tried to open rx_1seg_demo. However it did not work and it says missing block like the picture I attached. I followed you instructions on README and I thought installations were successful(I did not see any errors). Could you help me to solve this problem?

Thank you.

I now directly copied files in block folder and it does not show missing blocks. But it still has error which says

Traceback (most recent call last): File "/Users/hibikishiiba/gr-isdbt/examples/rx_demo.py", line 29, in import isdbt ImportError: No module named isdbt

Please make sure your PYTHONPATH variable contains directory where isdbt module is placed. After you adjust your PYTHONPATH variable and duly export it, you may test module isdbt import by invoking python in a terminal or a Python IDE like Idle, and trying the command import isdbt It should do the import with no error messages.

Thank you for the comment. Does it mean I have to open a path for the folder which is named isdbt? And Should i type “import isdbt” after that?

If you don’t mind could you show the commands for me?

Task: ensure your PYTHONPATH variable contains the directory where your isdbt module can be found.

1. Verify is this is really your problem. The command echo $PYTHONPATH should contain the directory where your isdbt module is placed. If the directory is present, this is OK and the origin of your problem must be sought elsewhere.

2. If you did a normal GNU Radio installation, you can try this: source <full path to your GNU Radio installation>/setup_env.sh You may find your setup_env.sh in your machine and use the full path obtained. After this, step 1) should show all paths to your GNU Radio installation, including the one where isdbt can be found. If the command was successful, you may try to invoke GNU Radio Companion and see if it works with isdbt. If this worked, you may include the "source" command at the end of your .bashrc for it to be executed each time you open a terminal.

3. More specifically, you can test isdbt import by issuing the following commands in a Linux terminal: python # opens a Python command line terminal import isdbt It should silently return. The command dir(isdbt) should show all components of the isdbt module. Write exit() or Ctrl-D to end the Python session.

Hi, If you had to copy the grc files into the folder it means that something went wrong during the installation process. Are you sure you had administrative privileges when you issued "sudo make install"?? best

Hi there, thank you for the response. When I execute the command sudo make install, terminal shows a result below.

Thank you.

I've just realized you are using Mac. Please note that our intended working environment is Linux, and we have not tested gr-isdbt on MacOS. The problem is probably there. You should check if there are any changes that need to be done to OOT as ours in order to work on Mac. best
