idb with multiple source

[roddur]

with multiple file as subroutine compiled with make, how can i set a breakpoint in some point? suppose, i want to find value of argument A on a subroutine S ....its easy if there is a single source code....but what if each subprogram is written as a seperate file?

I have gone through the intel's manual....so its not RTFM....may be U(nderstand)TFM?

Plz reply the post...even if it quite idiotic.....i am really stuck

You can set a break point in the subroutine using the subroutine's name. See the example below and the "br sub1" command.

[bash]$ cat -n sample1.f90
     1  program sample
     2  integer i
     3  call sub1(i)
     4  end

$ cat -n sub1.f90
     1  subroutine sub1(i)
     2  integer i
     3  print *,"i = ",i
     4  end

$ ifort -V -c -g sub1.f90

The point is that you can stop at subroutine entry, then set an internal break point, without reference a priori to the location of the source code. The debug-enabled code has a record of where the source was at compile time. If you have moved the source, the debugger should open a pop-up asking you to browse for it.
