Nonnegative Width Required

Symptom

The following error is reported during compilation:

star2doc.f:358.39:
 
               READ(CTOKEN(1:NCHAR),'(I)') IDLIST
                                       1
Error: Nonnegative width required in format string at (1)
make: *** [spider_linux_gfort.a(star2doc.o)] Error 1

Cause

The standard Fortran requires that a nonnegative bit width be specified for characters. If the bit width is not specified, an error is reported during GFortran compilation. No such error is reported in Intel Fortran.

Procedure

Change READ(CTOKEN(1:NCHAR),'(I)') IDLIST to READ(CTOKEN(1:NCHAR),'(I5)') IDLIST.
