Hi all

I am trying to compile VASP in parallel on 64 bit CentOS linux. And it gives the error

/usr/bin/ld: warning: i386 architecture of input file `../vasp.4.lib/libdmy.a(derrf_.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: warning: i386 architecture of input file `../vasp.4.lib/libdmy.a(dclock_.o)' is incompatible with i386:x86-64 output

drdatab.f:(.text+0x4bf): undefined reference to `_gfortran_os_error'
collect2: ld returned 1 exit status
make: *** [vasp] Error 1

I have used the 64 bit mkl land fft libraries.

Have anybody any idea , what is the problem?

please compile vasp.4.lib and vasp.4.6 CONSISTENTLY, i.e. with the same compiler, and for the same processor architecture

You are trying to link 32bit and 64bit together. Go to vasp4.lib directory, remove all *.o and *.a files, recompile. Should work.
