fix srd command

I changed diameters of wall particles from 0.5 to 1.0
But the peformance of program was stopped with an error as follows:
Too many big particles in bin
So i reset ATOMPERBIN parameter from 10 to 30 in fix-srd.cpp file
Then i run the following commands in src
make yes-srd
make openmpi
after running two these commands i saw change that i have made, back again to the initial state
But i dont know how i can recompile the code?

If you edited src/fix_srd.cpp instead of src/SRD/fix_srd.cpp
then doing make yes-srd wiped out your changes. See the
doc pages about building LAMMPS with packages. It's
all explained there.
