I have put all subroutines into a big file and now is better. But I got the following error. What should I do? f77 -o uneqm UNEQM.FOR UNEQM.FOR: In subroutine `optif': UNEQM.FOR:62: warning: call optif(nr,np,p,uneq,typx,typf,msg,ndigit,itnlim,ipr, 1 UNEQM.FOR:1397: (continued): SUBROUTINE OPTIF(NR,N,X,FCN,TYPSIZ,FSCALE,MSG,NDIGIT,ITNLIM,IPR, 2 Argument #15 (named `fpls') of `optif' is one precision at (2) but is some other precision at (1) [info -f g77 M GLOBALS] On Thu, 2003-09-04 at 16:02, zhu wang wrote: > On Thu, 2003-09-04 at 15:23, Toon Moene wrote: > > zhu wang wrote: > > > > > I am trying to compile some Fortran code, but I got the following error: > > > > > > $g77 -o uneqm UNEQM.FOR > > > > > > /tmp/ccovHZ8m.o(.text+0x60d): In function `MAIN__': > > > : undefined reference to `uneq_' > > > /tmp/ccovHZ8m.o(.text+0x690): In function `MAIN__': > > > : undefined reference to `dfault_' > > > /tmp/ccovHZ8m.o(.text+0x722): In function `MAIN__': > > > : undefined reference to `uneq_' > > > /tmp/ccovHZ8m.o(.text+0x739): In function `MAIN__': > > > : undefined reference to `optif_' > > > /tmp/ccovHZ8m.o(.text+0xa11): In function `MAIN__': > > > : undefined reference to `cspec_' > > > collect2: ld returned 1 exit status > > > > There are some routines (with names UNEQ, DFAULT, OPTIF, CSPEC) that are > > not included in UNEQM.FOR, but used by it.
