Hi, The documentation is here:
https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_GuideIn this case I think that only one block rather than a whole OOT needs to be ported to GNU Radio 3.8, so basically the only changes that need to be done is XML to YAML .grc files (gr_modtool helps with the conversion) and python2 -> python3 in case it is a Python block.
In case of doubt or problems, it helps to see what people have done in other OOTs. Most of them have maint-3.7 and maint-3.8 branches that you can compare.

The general approach is to make a new OOT module for the version you want, using gr_modtool, then move code from the old module to the new module as needed.On Fri, May 14, 2021 at 7:25 AM Aditya Arun Kumar <[email protected] <mailto:[email protected]>> wrote:Thanks Marcus. I was also thinking the same thing. Can you please link me to some porting guides, I am new to this and the last time I tried I failed miserably.

I think the most straightforward way would be to port the AMC block to 3.8. I wasn't aware of it existing only in maint-3.7!
