How to suppress creation of unwanted .DWF files

Accelerated Computing HPC Compilers Legacy PGI Compilers

With the Windows 11.9 PGI release, the compilers produce .DWF files even if one uses the -Mnodwarf option:

Reading rcfile C:\lang\PGI64\win64\11.9\bin\pgf95_rc
-Mnodwarf           Do not add DWARF debug information

Is it possible to suppress creation of these files by making changes to the settings in one of the *rc files?

Thanks.

Hi mecej4,

The .dwf files are part of the stripping process, so you can simply turn this step off (i.e. add -nostrip flag). However, your resulting executable may be bloated. Another option would be to have the output of the dwf file be sent to a temporary file instead. To do this, modify the ‘nt64rc’ configuration file. Look for the “strip” command:

command strip is
         help(Dwarf debug processing)
         tool(strip)
         set(OFILE=$dirname($input)/$basename($input).$POSTLINKSUFFIX)
         tempfile($OFILE)
         set(DFILE=$dirname($input)/$basename($input).$DEBUGSUFFIX)
         arguments($STRIPARGS $OFILE $input $DFILE);

Add a second ‘tempfile’ line as below

command strip is
         help(Dwarf debug processing)
         tool(strip)
         set(OFILE=$dirname($input)/$basename($input).$POSTLINKSUFFIX)
         tempfile($OFILE)
         set(DFILE=$dirname($input)/$basename($input).$DEBUGSUFFIX)
         tempfile($if($equal($DODWARF,),$DFILE))
         arguments($STRIPARGS $OFILE $input $DFILE);

Hope this helps,
Mat

Thanks, that worked. For the 32-bit compiler, the corresponding file to edit is win32rc.
