Error message in fortran

  1. Jun 23, 2008 #1
    I have a code in Fortran that I can compile but when I try to build it I get the following messages:
    error LNK2001: unresolved external symbol _DEVCRG@24
    fatal error LNK1120: 1 unresolved externals

    I guess that it does not understand it cannot find the subroutine DEVCRG, but I do not know the reason why...
    Please help

    DEVCRG is a library routine belonging to the IMSL® Fortran Numerical Math Library.
    I guess you need to link against this library to get it to work.
    Which compiler are you using and which OS?

    Thanks for the reply,
    I compile with Fortran Powerstation 4.0, Microsoft developer studio and my OS is windows xp sp2. Please tell me where can I download this library and how can I link it to my code?
