[FLASH-USERS] Missing Makefile in FLASH 4.8 Build for AlfvenAntenna

Dear FLASH Community,

I am trying to build the AlfvenAntenna problem in FLASH 4.8 on WSL Ubuntu,
but I am not getting the Makefile or any files in the object directory,
even though setup.py reports SUCCESS.

*Steps followed:*

cd ~/plasma_codes/FLASH4.8
rm -rf object
mkdir object
python3.10 bin/setup.py AlfvenAntenna -auto +ug +hdf5 -objdir=object
-site=MyLinux -verbose=DEBUG
cd object
ls


   - setup.py output ends with SUCCESS, but object/ is empty:

ls: cannot access 'Makefile': No such file or directory

*Additional info:*

   - Custom site MyLinux created from Prototypes/Linux.
   - flashPar.py exists in source/Simulation/SimulationMain/AlfvenAntenna.
   - Tried make -j4 in object/, but no targets are found.
   - Python 3.10 and WSL Ubuntu environment.

*Questions: I want to know-*

   1. Is it normal for setup.py to report SUCCESS but not generate a
   Makefile in object/?
   2. Are there environment variables or additional steps required to
   generate the Makefile and compile flash4?
   3. Could this be related to WSL, Python 3.10, or missing libraries?

Any guidance would be greatly appreciated.

Thank you.

Best regards,
Subhasish Bag
