[Pw_forum] Strange error within linking

[Sergei Lisenkov]

Dear PWscf users,

I met the strange error in linking stage. I have never seen it before. The machine is Xeon, cluster, Scali MPI, ifort 8.0, mkl61 library:

bp_radin.o: In function `radlg_':
bp_radin.o(.text+0x673): undefined reference to `f_iod'
bp_radin.o(.text+0x689): undefined reference to `f_iod'
bp_radin.o(.text+0x692): undefined reference to `f_iod'
bp_radin.o(.text+0x69e): undefined reference to `f_iod'
bp_radin.o(.text+0x6b4): undefined reference to `f_iod'

bp_radin.o: In function `radlg_':

bp_radin.o: In function `radlg1_':

bp_radin.o: In function `radlg1_':
bp_radin.o(.text+0x892): undefined reference to `f_stop'

How to solve it?

Thanks,
