Hi Lammps peopĺe!
I am trying to couple Lammps to other code and would like to see if
someone can help me in some difficulties.
As a starting point, I am trying to compile the example included
in ~/examples/COUPLE/lammps-quest
It was possible to build lammps as a library, using a modification of
the Makefile.openmpi file and a file called liblammps_openmpi.a was
created.
After that, when I try to compile the lmpqst.cpp using
make -f Makefile.openmpi
I receive the error message ():
...
lmpqst.o: In function `quest_callback(void*, long, int, int*, double**, double**)':
lmpqst.cpp:(.text+0x42): undefined reference to `lammps_extract_global'

collect2: error: ld returned 1 exit status

it seems to me that the compiler doesn't find
lammps_extract_global
which is a function included in the library.cpp code, included in
~/src
Can someone indicate to me how to make this function to be found ?
Thank you in advance,
Ricardo
