How to ensure the CPP option I added works?

[Zeng]

Hello, everyone! Wish you all the best!
I added codes to decay the passive tracer in step3d_t.F, as shown in the figure.

And I set a cpp option in .h file.

When I ran the case, the screen displayed as follow:

There is no cpp option of TRACER DECAY in the log. I am curious about if the cpp option works? Is there a way to prove that these codes have taken effect?(expcet run the case twice) And can I add the new cpp option through the above method?
Thanks for your attention and looking forward your reply!

The place to check is in the build directory. Look at step3d_t.f90 there to see if your conditional code is there.

For the output you were looking at, there is another file that needs to be modified to get that statement added: checkdefs.F
