Error occurs when compiling VASP.6.3.2 with AOCC

Hi all,

I encountered an error when compile VASP.6.3.2 with AOCC 4.0.0 by using the template makefile.include.aocc_ompi_aocl_omp.

...

What's the problem?

Thanks,

We currently did not test with AOCC 4.0.0. Please consider our recommended toolchains. That being said, we do want to support AOCC 4.0.0 in the near future, so I will investigate whether I can reproduce this issue.

Can you post the incar_reader.f90 file after the preprocessor. Then I can inspect it to see if something goes wrong in that step.

[martin.schlipf]

We installed the AOCC 4.0.0 and found the issue. There is a bug in the flang preprocessor for files with the ending .F. Because that traditionally indicates fixed format, the preprocessor cannot handle long lines with the __LINE__ macro in them.

Here is a list of fixes:

• Switch to a different preprocessor e.g. cpp.
• Add -ffree-form to the preprocessor (CPP in the makefile.include).
• Rename the files that fail to .F90 (note that would require changes to the makefile as well).

Hi Martin,

Thanks for your suggestions. We renamed all filename to F90 and successfully complied.
