hello gromacs users
i saw my em.log file after minimization no position restrain term is there
even i used -D  flag
; Include Position restraint file
#ifdef POSRES
#include "posre.itp"
#endif
; Strong position restraints for InflateGRO
#ifdef  -DSTRONG_POSRES
#include "strong_posre.itp"
#endif
; Strong position restraints for InflateGRO
#ifdef  -DSTRONG_POSRES
#include "backbone_posre.itp"
#endif

; Include ligand topology
#include "drag.itp"

; Ligand position restraints
#ifdef -DPOSRES_UNK
#include "posre_UNK.itp"
#endif

; Include POPC chain topology
#include "popc.itp"

; Include water topology
#include "gromos53a6_lipid.ff/spc.itp"

#ifdef POSRES_WATER
; Position restraint for each water oxygen
[ position_restraints ]
;  i funct       fcx          fcy             fcz
   1    1       1000000    1000000    1000000
   2    2       1000000    1000000    1000000
   3    3       1000000    1000000    1000000
#endif

; Include topology for ions
#include "gromos53a6.ff/ions.itp"
this my topology how can i put position restrain
 minim.mdp
define          = -DSTRONG_POSRES   -DSTRONG_POSRES   -DSTRONG_UNK

kindly help
