The errors you encounter suggest that these compilers do not exist or cannot be found in your environment. This often occurs when you haven't loaded the correct modules on your machine or when your PATH does not point to the correct compiler locations. Please make sure that the Intel compilers can be found during the VASP compilation process. This includes the Intel Fortran compilers used at the later stages of the compilation process.

In your terminal window, navigate to the VASP root folder (the one that has the makefile and makefile.include in it) and execute the following commands:

Code: Select all

icpc --version
which icpc

The first command invokes the icc compiler and simply prints its version to the console. The second prints the location of the icc compiler. Please, confirm for yourself that this location is indeed correct. If either of these commands fail, then the icc compiler is not found within your environment. In this case, please make sure that you have correctly installed the Intel toolchain and that it is made available to the environment where you compile VASP.

This will be available in upcoming VASP versions. However, if you have access to the older (legacy) Intel compilers, you should be able to compile as usual using the Intel makefile.include. Let me know how it goes.
