Hello VASP team,

I have the following error when I am compiling the vasp_gpu version. How can I solve this problem and what do you suggest?

hamil_gpu.F(205): error #6683: A kind type parameter must be a compile-time constant. [C_INTPTR_T]

Than you for your help！

If you want to use VASP on a GPU, we advise to upgrade to VASP.6. Over the last few years, we spent a lot of effort to port larger parts of the code to run on GPUs. The old GPU port is no longer maintained because the new OpenACC port covers many more features. See here for more details.

That being said, if you really need to use the old version, please tell us the exact compilers you are using and upload the relevant makefile.include.
