Re: [photran] How to use Intel idb as debugger

[Mike Garrahan <mgarraha@xxxxxxxxx>]

The idb GUI appears to run a backend called iidb, which emulates gdb
well enough for the Eclipse IDE to get by.

iidb needs to load certain shared libraries. I made this happen by
adding /opt/intel/Compiler/11.1/038/idb/lib/intel64 to environment
variable LD_LIBRARY_PATH prior to Eclipse startup. Your path should
match your specific ifort installation.

In your debug configuration, tab "Debugger," field "GDB debugger,"
replace gdb with iidb. If you want it to stop on startup, try replacing
main with MAIN__.

Good luck,
Mike

If you set a breakpoint in your Fortran code at a convenient place and click 'Resume', gdb should run to your Fortran breakpoint and stop with your Fortran source open.  The reason you see this behavior (if I am guessing correctly about your situation) is that debug launch configurations are created by default with 'stop at main()' enabled.  With Intel Fortran, the ifort runtime library provides the main() symbol so the debugger is stopping in ifort rtl code which it does not have any source for.  You can just ignore this stop at main() and click resume to continue into your Fortran code, or you can eliminate the stop at main() by disabling it in your debug launch configuration.  But make sure you set a breakpoint in your Fortran code either way so that your program does not just run to completion before you get a chance to debug anything.

I have a Kubuntu 9.04-system with the latest Intel Fortran 11 compiler and debugger. Compiling works fine but gdb cannot "read" the source files.
