LAMMPS build - "recompile with -fPIC" error

[Mskater]

New problem for LAMMPS build:

I had errors which said recompile with -fPIC due to a PIE error. After poking around a lot, I added the flag to the build command: make mpi -j4 -no-pie.
It ended with:
-L/usr/lib/python2.7/config-x86_64-linux-gnu -L/usr/lib -lpython2.7 -lpthread -ldl -lutil -lm -Xlinker -export-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions -o ../lmp_mpi
size ../lmp_mpi
A whole list of object files (*.o) are in the Obj_mpi directory (under the LAMMPS source directory ).
Is this an error? Because I cannot find an lmp_mpi executable.
What to do now? Thanks for any help.

lmp_mpi should be in the src directory, and "a whole list of object files (*.o) are in the Obj_mpi directory" is expected.

There is no lmp_mpi in the source directory. Yes I know the object files should be in Obj_mpi.
The errors now go like this for every object file (when I don't have -no-pie as a flag in the make mpi -j4), when I do, it doesn't even get this far :

/usr/bin/ld: fix_npt_cauchy.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC
(And on and on, naming all object files)
It's telling me to recompile all the object files differently somehow?
How to get over this error? Thanks!

What version of LAMMPS do you use? I think it's an issue related to LAMMPS itself. DeePMD-kit plugin does nothing to fix_npt_cauchy.

Yes, thanks, I know what you mean, it's about LAMMPS, but I was following the instructions on this website to build LAMMPS, (traditonal make), and something is missing. I am installing the March 2020 stable version. I don't know how to "recompile with -fPIC", and have read that it may mean something else, and so I'm stuck again.
