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 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

On a quick look at the code, it appears your Fortran functions are doing unformatted I/O. The problem with that is that the structure files created using unformatted I/O are (Fortran) compiler dependent. The cio.c file is also doing binary I/O, and the mapping of data read from such a file into actual data structures (in C) is also compiler dependent.
