upgrade OOT to 3.8

[t812206236]

@jcrona

I redo this upgrade and avoid unnecessary changes,The instructions I did below:

gr_modtool newmod nfc

cjq@cjq-Latitude-5288:~/prefix-3.8/src/gr-nfc$ gr_modtool add modified_miller_decoder
GNU Radio module name identified: nfc
('sink', 'source', 'sync', 'decimator', 'interpolator', 'general', 'tagged_stream', 'hier', 'noblock')
Enter block type: general
Language (python/cpp): cpp
Language: C++
Block/code identifier: modified_miller_decoder
Please specify the copyright holder: 
Enter valid argument list, including default arguments:

cd gr-nfc/
gr_modtool add modified_miller_decoder
cd lib/

# overwrite modified_miller_decoder_impl.cc  modified_miller_decoder_impl.h and update modified_miller_decoder.h

cd ..
mkdir build
cd build/

# I use pybombs, so my installation directory is /home/cjq/prefix-3.8/
cmake -DCMAKE_INSTALL_PREFIX=/home/cjq/prefix-3.8/ ../
make
cd ..
gr_modtool makeyaml modified_miller_decoder # auto generate block in yaml format

# copy all files except LICENSE, MANIFEST.md, README.md

For related tutorials, please refer to https://wiki.gnuradio.org/index.php/OutOfTreeModules.

The only problem is that this package does not implement the test, as if it was not implemented. In addition, it is not tested whether nfc is executed according to its logic. At present, it can only be compiled and run, and the block nfc_modified_miller_decoder can be seen in gr3.8, but I think there should be no problem. After all, I did not change the source code.

Also, you will see a lot of changes, but these changes are automatically generated by gr_modtool, the new oot3.8 seems to have changed a lot of things.

I can't seem to get it to work now. "make" is having error with theses lines of code:

1. "<+OTYPE+> *out = (<+OTYPE+> *)"

2. r ::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)),

3. " gr::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)) output_items[0];"

4. gr::io_signature::make(<+MIN_OUT+>, <+MAX_OUT+>, sizeof(<+OTYPE+>)))

5. const <+ITYPE+> *in = (const <+ITYPE+> *) input_items[0];

@KimlongSeng I don't know why you can't compile, but I want to say that some libraries used by gnuradio's series of things are not compatible with the latest libraries, so they made a thing called pybombs. If you don't use pybombs, you may not have a problem, but once there is a problem, you don't know whose problem it is, Therefore, it is recommended to use pybombs as your gnuradio running environment, so that you can do relevant development at ease
PyBOMBS ? The What, the How and the Why

[KimlongSeng]

Update:
I manage to get the miller_decoder block show up with getting an error in the gnuradio, and fix the nfc lib error by add path to python sys manually.

My last error is showing:

@t812206236 Have you ever encounter this error : module 'nfc' has no attribute 'modified_miller_decoder'.
it is from the auto generate gnu-radio python(graph flow

)

[t812206236]

@KimlongSeng I just tried and didn't encounter this problem

[KimlongSeng]

I see it is probably something to do with importing modual from python2+ to python 3+.
Thank you for the reply :) @t812206236

I really, really suggest you use pybombs,The following is its built-in script for setting up the environment

Did you see it? It has helped you select the tools you need

I reinstall gnu radio with pybomb, and it does not recognize the rtlsdr_source at first , but after installing rtl-sdr., it still show "AttributeError: module 'nfc' has no attribute 'modified_miller_decoder'" when i try to run it.
