Dear Vicki, for the following error you got, this is typical error for ifc compiler, In function `f_f77ioerr': : undefined reference to `__ctype_b' You can try to put the option '-i_dynamic' or '-lIEPCF90' in Linker Flags. Linker Flags: -L../SRC_lib -L/opt/intel/mkl61/lib/32 -Vaxlib -i_dynamic like this. Regards, Keisuke HATADA
