Topic: problem with "avr-size" (Read 2585 times) previous topic - next topic



I'm trying to use the avr-size utility unsuccessfully. I'm running Windows7

what i do is:
- open command prompt
- compile (verify) my sketch
- with command "cd" i move into my compiled sketch folder ( ex: C:\Users\Federico\AppData\Local\Temp\build2161693329745786396.tmp )
- write the command: avr-size MySketchName.cpp.elf and press enter...

What happen is:

"avr-size" is not recognized as internal or external command, an executable program or batch file

avr-size should be included in the avr-gcc toolchain that i suppose comes with Arduino IDE! Am I right?

Do you have any advice to get working this utility on my computer?

The operating system does not know where to find executables unless either

1.  The file is in a directory defined by the %path% environment variable


2.  You give it the complete path name as part of the command.

And, yes, you are correct: avr-size.exe  (and other avr-stuff) is under the arduino installation directory:


Append that directory to your %path%.  (In Windows XP, you can set and modify environment variables from the Control Panel->System->Advanced->Environment Variables box.  I don't know exact details for later versions of Windows.)

yes, but the ide invokes the programs explicitly, and does NOT modify your default system paths to include all of the binary directories that it provides.


so how can i modify something for get running avr-size.exe?


Like Dave said:  \\whatever\arduino-0022\hardware\tools\avr\bin

For example, I have a \bin\ directory where I put less formal installs, and I can do:
C:\Documents and Settings\Bill Westfield>c:\bin\arduino21\hardware\tools\avr\bin\avr-size.exe --help
Usage: c:\bin\arduino21\hardware\tools\avr\bin\avr-size.exe [option(s)] [file(s)]
Displays the sizes of sections inside binary files
If no input file(s) are specified, a.out is assumed
The options are:
  -A|-B|-C  --format={sysv|berkeley|avr}  Select output style (default is berkeley)
            --mcu=<avrmcu>            MCU name for AVR format only
  -o|-d|-x  --radix={8|10|16}         Display numbers in octal, decimal or hex
  -t        --totals                  Display the total sizes (Berkeley only)
            --common                  Display total size for *COM* syms
            --target=<bfdname>        Set the binary file format
            @<file>                   Read options from <file>
  -h        --help                    Display this information
  -v        --version                 Display the program's version

Within a particular session, the cmd window history functions are very useful.  If you're going to be doing this a lot, you can add the appropriate directory to your path:???
path c:\bin\arduino21\hardware\tools\avr\bin;%path%
(either manually, in some "avdev-setup.bat" file, or even autoexec.bat)


Wow thanks westfw and all others posted here!

For now, I used the temporary command:

Code: [Select]
path C:\Users\Federico\Desktop\arduino-0021\hardware\tools\avr\bin;%path%

to add the executable to the windows path, then move into the compiled sketch folder and launch the command:

Code: [Select]
...>cd C:\Users\Federico\AppData\Local\Temp\build4288029111388491449.tmp
C:\Users\Federico\AppData\Local\Temp\build4288029111388491449.tmp>avr-size SketchName.cpp.elf

And it works well!!

Now i need try to find the "autoexec.bat" and add the path there...
