cpp in fortran

cpp in fortran

[Ganesh Ramakrishnan]

sir,
         Will you please explain me how to drfine
function like macros in Fortran linux? I am using cpp
for getting the line number & file name of a
particular function. After that i am not able to
compile it using g77. The problem is i think, cpp is
not supporting the fixed format. 
I am defining this macro in a header file & including
it in fortran source file using #include.

#define fun(x) fun(x, __LINE__, __FILE__)
 
But in the output file, that particular line is going
beyont the 72 columns & because of that i am not able
to compile using g77.

 Will you please suggest one method to get out of it?

      Expecting earliest reply.

           Thanking you,
                              R.Ganesh

You could use the -ffixed-line-length-N option on the g77 command line
(where N is maximum length of the source lines you want to use; N=0
means: infinite).

Hope this helps,

cpp in fortran

[Ganesh Ramakrishnan]

Hi,


 I am defining this macro in a header file &
 including it in fortran source file using #include.
 
 #define fun(x) fun(x, __LINE__, __FILE__)
 
 But in the output file, that particular line is
 going
 beyont the 72 columns & it is not taking care of the
new line symbol '$' in fortran source code. It is
taking care of new line character with cpp which comes
with gcc-2.81 & gcc-2.95.
But in the new version (gcc-3.2) it gives the above
problem.

Can you please help me out in this.
 
              Thanking you,
                           Ganesh R

Could you send me the source code - I cannot deduce what's wrong from 
this description.

Thanks,
