Hello,

There is a Linux console tool (written in FORTRAN/C) which I want to port under Windows. It can be started with one parameter:

$gribprint gfs1.grib

Example output on the console:

--------------------------------------------------
rec GRIB Lvl Lvl Lvl Time Fcst
Num Code Code one two hour
--------------------------------------------------
1 11 1 0 0 2005-10-11_00:00 +00

I have success with the compilation of the program under Windows. If I run it without argument it works fine and displays a help message. But if I run it with an argument (gfs1.grib) it starts to read the file and then it gives error message (it says that error log is created but I can't find it, W2K). The gfs1.grib file is ok. I'm wondering where is the problem and I guess that it's in the file:

/regrid/pregrid/util/cio.c

where are the I/O (read & write) functions. Here are the original sources for UNIX/Linux:

ftp://ftp.ucar.edu/mesouser/MM5V3/REGRID.TAR.gz

Thanks for any ideas!


Best Regards,

Angel

Since I don't have any compiler that will compile the 87 or so FORTRAN 90 files in your bundle, there's no way that I could help debug the lone C file there. In other words I can't do anything specific to help.

If I had this project and I observed that it bombs when I give it a command line argument, I would start with the command line argument and work forward from there. Find the FORTRAN files with "handle_arguments" and "getarg" function definitions and put in debugging write() statements to show exactly what the program is working with at each step.

If I thought there was a problem with I/O, and particularly with that one stinkin' C file, I would create a small project using whatever I/O routines that the big job uses and I would track things down with the small job: if it opens a file for writing, where does it put the dang thing. I would sprinkle lots of FORTRAN write() statements, and, perhaps, a few C printf() statements around the landscape. Things like that.

(Actually, I might first go to the compiler vendor's (Portland Group???) forum and poke around there for a while.)

Good luck,

Dave

Hi Dave,

Thank you very much for you response. As I see you are a regular visitor to this forum and you know a lot about the programming:-)

The compiler is PGI pgf90 from http://www.pgroup.com.
