Hi,
I need to build VASP 5.2.12 with GCC 4.8.1.
After fixing a couple of issues with makefile.linux_gfortran,

[cchang@login1?vasp.5.2.12]$?diff?Makefile?makefile.linux_gfortran
52,53c52
<?FC=gfortran?-ffree-form?-ffree-line-length-0?-ff2c?-fno-second-underscore?
<?#FC=/usr/local/gcc-4.6/bin/gfortran46?-ffree-form?-ffree-line-length-0?-ff2c?-fno-second-underscore?
---

<?FFLAGS?=??-FR?-lowercase

I try "make"ing. The build fails at dfast.f90 with the following:

Code: Select all

gfortran?-ffree-form?-ffree-line-length-0?-ff2c?-fno-second-underscore??-FR?-lowercase?-O3??-c?dfast.f90
dfast.f90:182.10:

??????USE?dfast
??????????1
Error:?'lincom'?of?module?'dfast',?imported?at?(1),?is?also?the?name?of?the?current?program?unit

How do I fix this? The gfortran makefile supplied with the source code appears unusable, at least for GCC 4.8.1.

Thanks

i am having the same issue with gfortran 4.7.1. Have you solved this? working on the matter myself.
The only difference is in the debuging message being reported

dfast.f90:155.10:

USE dfast

Error: 'lincom' of module 'dfast', imported at (1), is also the name of the current program unit

Has anyone got any progress on this? according to
http://www.nsc.liu.se/~pla/blog/2011/06/28/vaspcompile/
it seems to be an issue with circular reference into the dfast source code which is buggy. Howeverm ifort 13 seems to be permisive and compiles a vasp executable which seems to work correctly. The alternatives are 1) downgrade to gcc 4.4 or 2) pathc the source code which is not recommendable if you dont know what you are doing.
