VASP Forum

Dear all,

I tried to compile VASP as a local installation on a M1 Mac,
so I tried the recommendation of the VASP wiki using:

gcc-14.2.0
openmpi-5.0.7
fftw-3.3.10
openblas-0.3.29
netlib-scalapack-2.2.2
hdf5-1.14

however running the resulting executable does run but aborts always with the message below.
Anybody any thoughts?

Hello!

The error you observed is linked to an already known incompatibility with GCC > 14.2.X, see also here. I assume that homebrew installed not exactly the packages with versions listed on the Wiki here but probably newer ones, maybe even GCC 15, you can check with:

gfortran --version

Somewhere between GCC 14 and 15 the Fortran compiler became more strict and now trips over previously silently ignored non-conforming format specifiers. In the upcoming VASP release these issues are already resolved but for VASP ≤ 6.5.1 you can add the flag -std=legacy to the FFLAGS variable in your makefile.include. Then perform a make veryclean and compile VASP from scratch.

Hope this helps!

All the best,
Andreas Singraber

Dear Andreas,
