invalid fix style

Dear LAMMPS Developers

In the current versions (14 Nov12, 4th Dec12), fix rigid command is not working.
I am getting an error:
ERROR: Invalid fix style (modify.cpp:666)
I have tested the given example also (/examples/rigid/in.rigid ) and got the same error.
Other rigid fixes such as rigid/nve, rigid/nvt and rigid/npt are also show the same error.

However, it works fine in older versions(29Jan2012, 12April,2012).

In particular, I would like to use rigid/npt which is added in recently versions.
I would appreciate if you look into the problem.

Thank you.

oh, it does work.

have you looked up what this error means?

there is no problem outside of you not compiling
LAMMPS properly for your purposes. all the rigid
styles have been made optional and moved to the
RIGID package. if you want to use them, you have
to install that package before compiling.

in short: no problem that needs looking into.

axel.

Thanks Axel for the information.
