title: Mixed Programming Fortran and C
body: <p>I am a Theoretical Physics research student, working in Cosmology. In course of my research I have use to rather huge library of Fortran codes and I used C for my programming needs. </p>
  
  <p>I have been able to link the two programs in numerous test files and they work brilliantly. But for them I have been using the object files to link them all. But when I tried to run the real deal through C, include reference to the Fortran header files. They seem to integrate and call each other fine but the format of the Fortran header file is incomptible with the C compiler, so when it jumps to the header file it start throwing errors that it cannot understand the syntax. </p>
  
  <p>For example, the Fortran header file defines double variables with real*8 so when C reads them it throws errors. The same happens with comments in the file as well.</p>
  
  <p>So, I want to ask is there any way through which I can go about this problem? i.e. make the fortran format header file readible through C.</p>
  
  <p>I looked over the internet and found confusing answers, and I do not know which one to follow. Any help in this matter will be appreciated :)</p>
