My bad. I should have posted the link to the issue with that statement.
I would have submitted these issues in the appropriate places had I known. It took two weeks before someone (thanks again, justjed) steered me to the Savannah site.

Now the big question. Is anyone else using avr-gcc v4.5.1?
I'm ok with being "the only one". I'm comfortable being the lead dog in the pack.


At least with free software, you can fix it yourself.

"Free" is neither necessary or sufficient for being able to "fix it yourself."  Universities and capable customers have had "source licenses" for otherwise proprietary (and expensive) software, and been fixing their vendors' bugs, since ... forever.

And how wonderful it is that Free Software and Open Source have provided that capability to everyone, not just those who have deep pockets for buying source licenses.

That's good, because unless you are the lead dog, the view is always the same.  :D



I found the ethernet problem and have posted all the bugs and fixes with Arduino and Savannah.

It is good to be back in a Linux environment again. All seems to be working great.

Arduino V0022
avr-gcc v4.5.1
avr-libc v1.7.1
gcc v4.5.2

I received notice this morning from the Savannah crew that the math.h bug in delay.h will be corrected in avr-libc v1.7.2

One down, two to go!  :)

Thanks, justjed!

UPDATE: I just got an email from the savannah crew that the bug fix did not make it into the avr-libc-1.7.2 package. That is out in a beta version now at the savannah site.

It will be in the avr-libc-v1.8.0 version. So if you plan on using v1.7.2, also plan on removing that bug yourself.


Update: For you Debian and Ubuntu repository users, the new avr-libc version with this patch are going into your repositories. I just received this:
Comment #7 on issue 604 by showard...@gmail.com: wiring.h round macro causes error with avr-libc-1.7.1 fix

Linux distributions just upgraded their gcc-avr to 1.7.1 too. Debian/Ubuntu/Mint's version of arduino has this patch:
