I have been running vasp 6.4.0 for a while without problems and had been running vtst tools in vasp.6.3.2. I followed the instructions under "Installation" on the vtst tools pages (the same way I had followed them for vasp.6.3.2, but I ran into a problem during compilation. In particular, the compilation stopped for dynmat (a source file that was untouched from a functional vasp.6.4.0 installation). It seems that the modifications made to the source main.F may be causing this problem. Any suggestions as to what to try next?

I thought it would be prudent to add the line that the error in dynmat.F

CALL RD_POSCAR(LATT_CUR, T_I, DYN, &
NIOND,NIONPD, NTYPD,NTYPPD,IO%IU0, IO%iu6)


The corresponding line (57) in the RD_POSCAR definition (in poscar.F) is:

SUBROUTINE RD_POSCAR_HEAD(LATT_CUR, T_INFO, &
& NIOND,NIONPD, NTYPD,NTYPPD, IU0, IU6)
