Under 1.0 ,
the tone library reported a warning when compiling,
the 1.01 , seems to have added more warnings.
are these reported here ?
are they fixed , or as 'just' warnings are they ignored ?
I just compiled the following example tone sketches on IDE v1.0.1 with no warnings or errors.
toneKeyboard
toneMelody
toneMultiple
tonePitchFollower
If you are using pre-v1.0 sketches on the newer releases (v1.0 or v1.0.1), you may need to modify that sketch code.
I hope the "dr" in your username means doctor. I have a pain right here. What should I do about it?
have you the verbose warnings turned on ?
I still have the following popping up in the verbose warning list.
C:\Program Files\Arduino\arduino-1.0.1\hardware\arduino\cores\arduino\Tone.cpp:93: warning: only initialized variables can be placed into program memory area
The Arduino libraries are pretty flakey - you have to compile them with all
warnings off. To fix the "initialized variables" error, add:
// Re-define PROGMEM (34734 – [4.2/4.3/4.5/4.6 Regression][avr] attribute((progmem)) not handled properly in C++)
#undef PROGMEM
#define PROGMEM attribute((section(".progmem.data")))
to the top of Arduino.h.
I'm not sure if this caused by a new version of GCC, or just an old bug
recently exposed. Anyhow, if you have doubts about where the strings
are actually going, check with avr-objdump.

being new to arduino
I'm an asic engineer,
I'm sad that the libraries of a well established item like the arduino , are considered less than solid.
how do we get the fix's into the next release ?
how do we get the fix's into the next release ?
File a report here. Having the fix included will speed up things.

thank you
issue 963 raised !
I hope the warngings are fixed as its very off putting and over time saps confidence in Arduino
Have faith! Every bug and fix I have filed has been fixed. 
warning: only initialized variables can be placed into program memory area
This one is actually a bug in the compiler. Alas, one that ended up being "fixed" by having the compiler people declare that most of the avr-libc "pgmspace" implementation was "invalid."
oh dear
a can of worms,
any chance the other warnings can be fixed ?
for this warning, could we initialise the variable like the warning asks ?

I think it is an old bug exposed. My version of avr-gcc in my Ubuntu install shows 4.5.3 with Ubuntu patches. However, that is not the version that is used by the Arduino IDE. That is avr-gcc v4.3.2. Here is the thread that enlightened me:
http://arduino.cc/forum/index.php/topic,108211.0.html
I would try to help, but I will not waste my time on antique gcc versions.
appreciate your comment
what is avr-gcc might be a good question,
OK, I do know about gcc,
but did I not just install arduino on windows and I guess gcc came with it ,
or did I have to install gcc seperatly ,
does the team need to include a new gcc in the arduino distribution
or do we need a way to upgrade gcc on windows machines.
and is this true of all the warnings that pop up in the compile windows ?
I'm not a big Windoze fan, so that part I will presume. I think the Arduino crew is trying to get a stable version working on all operating systems. Can't blame them for that, but I think that version is a bit out of date.
WinAVR uses avr-gcc 4.3.2 and avr-libc v1.6.4. I believe that was a new release in 2008. Before upgrading (downgrading?) to IDE v1.0, I was using avr-gcc v4.5.3 and avr-libc v1.7.1 with IDE v0022. ??
As I understand, avr-gcc uses GCC with AVR code and the AVR library (avr-libc).
hi
won't get into the windows v linux v mac v what ever you want
thats like asking what is your fav editor !!!!
I always liked Vi and ed, but there you go,
I now use a windows based editor,
so,
is avr-gcc 4.3.2 quite old then ?
does the team up grade this or is it possible / practical for the user to do so ?
hay, I could always run a VM under windows to run Ubunto on,
is that the way around the problem :->
I'm with you. I don't care what OS you prefer, and that is why I understand the Arduino crew's quest to get a standard IDE version working.
Those versions are about 4 years old if they used them to build WinAVR in 2008. What Arduino IDE version was current in 2008? What Arduino hardware was available then?
any way we can fix the bug,
or do we have to wait ?
can we upgrade the avr-gcc ?
Here is a recent developer mailing list discussion about the AVR tool-chain:
http://arduino.cc/pipermail/developers_arduino.cc/2012-June/006856.html
so , do i get this
the latest win avr is 2010, which is newer than the one that comes with arduino ide.
and the warnings that are caused by the compile are due to the old winavr,
does that mean we should download and install the 2010 winavr ?
