title: DISLIN double-precision libraries
body: <p>I am trying to compile a program written in FORTRAN that plots graphs using the DISLIN libraries, but all data is in double precision. I cannot lose this precision, so passing everything to simple precision is not an option. When I attempt to link to the double precision libraries (_d), I still get the following error I would expect had I linked to simple precision libraries:</p>
  
  <pre><code>call graf(-1.D0, 1.D0, -1.D0, 2.D0/10.D0, -1.D0, 1.D0, -1.D0, 2.D0/10.)
           (1)
  ERROR: Type mismatch in argument 'ax' at (1); passed from REAL(8) to REAL(4).
  </code></pre>
  
  <p>I also get other such errors in all plotting statements. My compiling command is (gfortran):</p>
  
  <pre><code>gfortran modulename.f95 progname.f95  C:\dislin\disgf_d.a -luser32 -lgdi32 -lopengl32
  </code></pre>
  
  <p>Note that disgf_d refers to the double precision libraries. Does anyone have any ideas here?</p>
  
  <p>Relevant code:</p>
  
  <pre><code>call metafl("XWIN")
  call disini()
  call graf(-1.D0, 1.D0, -1.D0, 2.D0/10.D0, -1.D0, 1.D0, -1.D0, 2.D0/10.D0)
  do i = 0, m
      Z(i) = -1.D0 + (2.D0*i) / m
      Y_Z(i) = Int_g(Z(i))
  end do
  call curve (Z, Y_Z, m + 1)
  do i = 0, m
      Y_Z(i) = g(Z(i))
  end do
  call curve (Z, Y_Z, m + 1)
  call endgrf()
  call disfin()
