Hello,

Recently, I tried to install VASP 6.1.1, but I fail to execute due to segmentation fault error.
I wonder how to solve the segmeation fault after compling VASP

The following is my installation enviroments.
1. windows_WSL2 (Ubuntu 20.04, gcc, gfortran default version 9)
2. intel paralell studio cluster 2018 update 4 (default installation path: /opt/intel/...)
2. VASP: 6.1.1 version

I tried to compile the following combinations.
1. GNU compilers + GNU library > compilation and execution compeleted
2. GNU compilers + intel MKL > compilation and execution compeleted
3. intel compilers + intel MKL > compilation compledted, but segmentation fault error after execution.

When I used intel compiler and MKL combination, I got the following error

I utilized the default file in /ARCH/makefile.include_intel,
and modified CXX_PARS = icpc including std=c++11 option since it cause any error without the option.

We did not perform tests on the WSL2_ubuntu as part of our internal testing.

Here are some things you can try to debug the problem:
1. The backtrace you posted is not very informative, could you recompile by changing the makefile.include Some more information about debugging with intel here:
https://software.intel.com/content/www/ ... tions.html
2. Could you show which libraries your VASP executable is effectively linked with? 3. Have you tried the exact same compilation (makefile.include and the same version of intel) on a linux machine with ubuntu if you have one?
I recommend comparing the results of step 2 with what you obtain on the linux machine.
I assume that ubuntu on WSL2 should produce a similar executable but its a good idea to check.

PS: Note that the compilation with gcc9 is not officially supported yet.
Some users have reported issues:
forum/viewtopic.php?f=2&t=17831
Our internal testing also revealed other issues besides those resported here.
I recommend you use gcc7 for the compilation.
Here is the list of our recommended toolchains:
wiki/wiki/index.php/Toolchains
We will support gcc9 in the next VASP update.
