| Common Error | Likely Cause | Potential Fix | | :--- | :--- | :--- | | | Compiler version incompatibility with the source code. | Try a different compiler version (e.g., older Intel) or apply the latest official VASP patch. | | Error: Assignment to contiguous pointer from non-contiguous target | Strict Fortran 2008 compliance of newer gfortran versions. | Compile with -std=legacy flag or use an older GCC version. | | **"cannot create directory build/std': File exists"** | An incomplete or failed previous build left artifacts. | Run make veryclean to clean the build directory completely before recompiling. | | **Linking errors or "undefined reference"** | Missing or incorrectly linked libraries, especially MKL or FFTW. | Double-check the LLIBS and INCS paths in your makefile.include . Ensure that the MKLROOT` environment variable is set correctly or specify the full path. | GNU builds work, but Intel compilers with MKL
