[lammps-users] Error: kspace style is incompatible with pair style

Hi all,
I am simulating an ionic liquid system, and

I need to have the long range interaction calculated.

When I put the input like:

pair_style lj/cut/coul/long 10
kspace_style pppm 0.0001

I get this error Error: kspace style is incompatible with pair style
But as per the manual this combination should work fine.

Now, if I do not use long interaction like below it works fine.

pair_style lj/cut/coul/cut 15 15
#kspace_style pppm 0.0001

What may be wrong and how do I solve this problem and calculate long range interaction.

Thanks for suggestions

this works for me. please produce a full
self contained input that reproduces this
error message and let us know which
version of lammps you are using exactly.
