Compiling VASP on M1 Mac

Written by Alex Ganose @utf and Janosh Riebesell @janosh. Published 2022-03-28. Last updated 2024-03-30.

1. Install Xcode command line tools:

   xcode-select --install

2. Install dependencies using Homebrew:

   brew install gcc openmpi scalapack fftw qd openblas

   Optionally, add hdf5 for HDF5 support in VASP.

3. Compile VASP:

   These instructions are for VASP 6.4.1 but should work with minor adjustments for other versions.

   cd /path/to/vasp-6.x.y
   cp arch/makefile.include.gnu_omp makefile.include

   Edit makefile.include in the VASP src directory:

   • Add to CPP_OPTIONS:

     -D_OPENMP \
     -Dqd_emulate

   • Change all instances of gcc to gcc-13 and g++ to g++-13

   • Add after LLIBS = -lstdc++ to emulate quad precision:

     QD ?= /opt/homebrew/
     LLIBS += -L$(QD)/lib -lqdmod -lqd
     INCS += -I$(QD)/include/qd

   • Set SCALAPACK_ROOT ?= /opt/homebrew

   • Set OPENBLAS_ROOT ?= /opt/homebrew/Cellar/openblas/0.3.20 (Double check this is the path on your system)

   • Set FFTW_ROOT ?= /opt/homebrew

   • (optional but recommended by VASP) For HDF5 support, add

     CPP_OPTIONS+= -DVASP_HDF5
     HDF5_ROOT  ?= /opt/homebrew/
     LLIBS      += -L$(HDF5_ROOT)/lib -lhdf5_fortran
     INCS       += -I$(HDF5_ROOT)/include

   • Append getshmem.o to OBJECTS_LIB in makefile.include (VASP wiki)

     - OBJECTS_LIB = linpack_double.o
     + OBJECTS_LIB = linpack_double.o getshmem.o

   • In src/parser/makefile, change (as noted by @zhuligs):

     - ar vq libparser.a $(CPPOBJ_PARS) $(COBJ_PARS) locproj.tab.h
     + ar vq libparser.a $(CPPOBJ_PARS) $(COBJ_PARS)

     Do not replace the tab at the beginning of the line with spaces!

   • In src/lib/getshmem.c, add the line #define SHM_NORESERVE 0 (VASP forum):

     /*output: shmem id
     */
     #define SHM_NORESERVE 0 // this line was added
     
     void getshmem_C(size_t _size, int *_id)

   • In makefile.include, update the parser section (VASP forum):

     # For the parser library
     CXX_PARS = g++-13
     - LLIBS = -lstdc++
     + LIBS += parser
     + LLIBS = -Lparser -lparser -lstdc++
     QD ?= /opt/homebrew
     LLIBS += -L$(QD)/lib -lqdmod -lqd
     INCS += -I$(QD)/include/qd

4. Finally, run:

   make all

   If a previous compilation failed, remember to run make veryclean to start from a clean slate. Fixes gfortran errors like

   Fatal Error: string.mod not found

If successful, the VASP binaries will be in src/bin. Test with make test.

Last Tested on 2024-03-30

Confirmed working with VASP 6.4.1 on M1 Pro with Sonoma 14.2.1 and [email protected].

Resulting makefile.include with all modifications

See makefile.include.

Benchmarking

Initial performance testing suggests optimal parameters for the M1 Pro chip with 8 performance, 2 efficiency cores and 16" MBP cooling are

Thanks @janosh for these instructions on my M2 Pro Macbook, running macOS Ventura. I tried using them to compile VASP 5.4.4. I made just two tiny tweaks to your makefile.include for newer versions brew gave me for gcc and openblas, i.e. gcc-11 -> gcc-13 and openblas 0.3.20 -> 0.3.23. Things go ok up to the link stage, but then I get an Undefined symbols for architecture arm64 error, see command line output below. Have you (or anyone else compiling VASP on Apple Silicon) ever come across these errors, and would you have any idea how to fix them?

Kind regards, Peter

Having this same problem on my M2 Mac, appreciate any help!

I have this error showing up all the time "make libparser.a
make[1]: *** No rule to make target sites.o', needed by libparser.a'. Stop.
make: *** [all] Error 2"

My version of gcc is 13.0.1, so instead of making gcc-11, I used gcc-13. The path in the makefile.include was also changed accordingly. However, the returned error is the same. Can anyone please help? Thank you!

I've been trying to compile vasp6.4.2 on m2 mac, but I get this error message:
ld: unknown options: -commons
I used the makefile.include as posted by @lauren-walters with gcc-13 and g++-13. Perhaps someone also got this error and found some fix?
Many thanks in advance!

Fix for "Undefined symbols for architecture arm64"

I've found the solution to the 'Undefined symbols for architecture arm64' errors I posted about earlier in this thread, and I am now running the standard version of VASP 5.4.4 on my M2 Macbook Pro running macOS Sonoma 14.1.1. There are a number of tweaks that helped me get things working, which I gathered from a VASP wiki page, various VASP forum threads, and earlier in this GitHub Gist thread. Let me list those here:

1. Include getshmem.o in the makefile.include, so that you get a line:

   OBJECTS_LIB = linpack_double.o getshmem.o

   As described on the VASP wiki page.

2. In src/parser/makefile, adapt the line:

   ar vq libparser.a $(CPPOBJ_PARS) $(COBJ_PARS) locproj.tab.h

   to:

   ar vq libparser.a $(CPPOBJ_PARS) $(COBJ_PARS)

   As noted by poster zhuligs some posts above here. Do not replace the tab at the beginning of the line by blank spaces, as happens automatically with posts here. The multiple blank spaces at the beginning of the line must be a tab instead.

3. In src/lib/getshmem.c, add the line #define SHM_NORESERVE 0 to make part of the file read:

   /*output: shmem id
   */
   #define SHM_NORESERVE 0
   
   void getshmem_C(size_t _size, int *_id)

   As described in the VASP forum page.

4. In makefile.include, make the parser section as follows:

   # For the parser library
   CXX_PARS = g++-13
   LIBS += parser
   LLIBS = -Lparser -lparser -lstdc++
   QD ?= /opt/homebrew
   LLIBS += -L$(QD)/lib -lqdmod -lqd
   INCS += -I$(QD)/include/qd

   As learned from the VASP forum page.

That should do it.

@pavlvs-pinto
I did not have the problem with -commons option when compiling VASP 5.4.4, but I did get that problem while trying to compile another atomistic simulation code on my M2 Macbook, i.e. the mpi version of the lammps code. Some searching lead me to a comment that suggests that the problem lies in version 15.0 of the Xcode tools. Rumour has it that it may get fixed in v15.1:
https://community.intel.com/t5/Intel-Fortran-Compiler/Mac-Xcode-15-0-unknown-options-commons/m-p/1536100
If you have access to an Apple Silicon Mac that still has an older version of Xcode, you could see if you can compile on that.

Thanks @tpcklaver for the last post and detailed instructions; I successfully compiled vasp6.4.2 in m2 MacBook Pro with macOS Sonoma 14.1.1 and Xcode-15.1 beta 3. Before you start the compilation, make sure you have installed the correct CLT version, you can check it with:
brew config

   as describewd in the VASP forum page https://www.vasp.at/forum/viewtopic.php?t=15106
4. in makefiule.include make the parser section as follow:
   #For the parser library
   CXX_PARS = g++-13
   LIBS += parser
   LLIBS = -Lparser -lparser -lstdc++
   QD ?= /opt/homebrew
   LLIBS += -L$(QD)/lib -lqdmod -lqd
   INCS += -I$(QD)/include/qd
   as learned from the VASP forum page https://www.vasp.at/forum/viewtopic.php?f=2&t=17477

That should do it.

These tricks worked for me. Many thanks to @pavlvs-pinto and @janosh and all.

I'va met this problem when compiling vasp6.4.3 on M2 chip, macos 14.5, gcc-14, and Xcode 15.4. Does anyone know how to fix it? Many thanks.

Hi @weiwan7,

I just recompiled VASP6.4.2 on an M2 MacbookPro, macOS 14.5, Xcode 15.4 and gcc-13 (the latter via homebrew). So it's close to your situation. I did not encouter the missing -ld_classic error. Where are you getting your fortran from, homebrew, Macports, or something else still? And what lines do you have in your .tcshrc/.bash_profile/etc files for your LIBRARY_PATH variable?

Hi @tpcklaver ,

Thank you for your kind help and reminder. I uninstalled Anaconda (possible conflict) and it works fine now. But still got the error "ld: warning: -commons use_dylibs is no longer supported, using error treatment instead". Is this error serious? Or can I just ignore it?

Hi @weiwan7,

I wouldn't worry too much about the warning. It seems that with every update of macOS, Xcode, Homebrew/Macports, or some of the major packages within Homebrew/MacPorts, such small issues can arise. And then after another update, they get ironed out again.
Just test your VASP binary on Apple Silicon against some runs carried out on orther platforms. That is a good basis for deciding if your VASP bianry is working propoerly or not.

Hi everyone,
I use MacBook M1 with Sonoma 14.5. I install VASP 6.1.0.
As following the guideline above, I have got these messages.
