Hi Josh - thank you for your help !
I have been following the instructions from the porting guide:
https://wiki.gnuradio.org/index.php/GNU_Radio_3.9_OOT_Module_Porting_Guide
----------------
Porting from 3.8 to 3.9 can be achieved most simply by creating a new OOT
module (with the same name as the 3.8 OOT but in a different directory),
then performing some manual steps
1. Use the 3.9 gr_modtool to generate a module with the same name (in
another directory)
2. Copy the python folder from 3.9 OOT into your 3.8 OOT
3. (in 3.8 OOT) Add the bindings directory to the python directory
CMakeLists
./python/CMakeLists.txt → add the line:
add_subdirectory(bindings)
4. (in 3.8 OOT) Call gr_modtool bind for each block in your OOT
...
-----------------
I have not created anything in the 3.9 directory except using gr_modtool
new and add, nor have I copied in any code
from 3.8 directory to the 3.9 directory. I was under the impression that
step 4 would modify my 3.8 code so that I could
then copy it from the 3.8 directory over to the 3.9 directory.
There are significant file differences between the newly created 3.9 and
the existing 3.8 with conflicts in the /lib directory:
the hermesNB_impl.h and .cc and hermesWB.h and .cc files differ
significantly in content.
Do I need to first look through the code and figure out how to merge the
3.8 and 3.9 .h and .cc files together?
Then do I put those merged file into the 3.8 or the 3.9 directory?
