Invalid pair style


i am using pair_style meam, and it gives me an error invalid pair style. I am not sure if meam is installed or not! But i have a copy of the commands I used in the installation:

cd ./MAKE

cp Makefile.g++3 Makefile.g++3_ORIG

Edit Makefile.g++3: CCFLAGS = -O


you should add the meam package to the build (make yes-meam), but before compiling it, you should first compile the meam library in lib/ (it has a README file with instructions). See also
