VASP Forum

I'm trying to Compile VASP 6.6.0 with intel fortran and mkl. I get a link time error:

ld: main.o: in function `MAIN__':
main.f90:(.text+0xb83f): undefined reference to `sync_vcaimages_'
make[2]: *** [makefile:154: vasp] Error 1

I searched with grep through the source code and I can't fine a definition for sync_vcaimages.

Any suggestions?

Thank you.

Hello!

The subroutine SYNC_VCAIMAGES is at the end of the file chain.F. I could not find a reason why the linker would not be able to find it... could you please paste or attach your makefile.include? Furthermore, please give us the exact version of the Intel compiler you are using, e.g. by executing:

ifort --version
# or, alternatively,
ifx --version

Thank you!!

All the best,
Andreas Singraber

Thank you, Andreas.
I had messed up because I added the tst modifications. That replaces chain.F with one that doesn't include the SYNC_VCAIMAGES routine which is new in 6.6.0.
Fixed it now.
