Descriptions of options

Reference Guide

For example:

   foo.r90: c:\iar\product\include\stdio.h

   foo.r90: d:\myproject\include\foo.h

To generate a listing of file dependencies to the file 

listing.i

, use:

iccavr prog --dependencies=i listing

To generate a listing of file dependencies to a file called 

listing.i

 in the 

mypath

 

directory, you would use:

iccavr prog --dependencies mypath\listing

Note: Both 

\

 and 

/

 can be used as directory delimiters.

An example of using 

--dependencies

 with a popular make utility, such as gmake 

(GNU make):

Set up the rule for compiling files to be something like:

     %.r90 : %.c

           $(ICC) $(ICCFLAGS) $< --dependencies=m $*.d

That is, besides producing an object file, the command also produces a dependency file 
in makefile style (in this example, using the extension 

.d

).

Include all the dependency files in the makefile using, for example:

     -include $(sources:.c=.d)

Because of the dash (

-

) it works the first time, when the 

.d

 files do not yet exist.

--diag_error

--diag_error=tag,tag,... 

Use this option to classify diagnostic messages as errors. An error indicates a violation 
of the C or C++ language rules, of such severity that object code will not be generated, 
and the exit code will be non-zero. 

The following example classifies warning 

Pe117

 as an error:

--diag_error=Pe117
