https://bugzilla.novell.com/show_bug.cgi?id=676024 https://bugzilla.novell.com/show_bug.cgi?id=676024#c1 --- Comment #1 from robert spitzenpfeil 2011-03-02 13:20:05 UTC --- Just so I don't appear as a lazy half-wit: I tried to compile binutils/avr-libc/avr-gcc according to the user-manual on the avr-libc website. I tested 4.3.x and 4.4.x and 4.5.2 - all of them lack essential patches to activate device support for the ATtiny4313. There are several patches out there, one on a freebsd site I stumbled upon and one can be found on avrfreaks.net, but they seem to be for vastly different versions. http://www.freebsd.org/cgi/cvsweb.cgi/ports/devel/avr-gcc/files/patch-newdev... http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=801807#801807 I managed to get one version to compile and avr-gcc at least accepts 'attiny4313' as mcu parameter, but later the linker complains about a missing object file for this cpu (but it exists). Whoever got the 4.3.3 packages going last time might have a better chance to apply the patch(es) to avr-devices.c than me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Apparently avr-gcc doesn't have a problem with these, but avr-g++ doesn't know about these at all. This can be resolved by adding #include to the top of

From what I've read in the most recent forum post I referred to, 'Bingo600' will look into this issue and if it is indeed resolved by adding only this include, he'll build some debian packages, which will be linked to on avrfreaks.net.

There's still the issue of Atmel not having provided the patches used for 'their' latest WinAVR (part of the new and infamous AVR-Studio 5 - a 520MB .net bloat - that's the size of the installer, not unpacked). As I can't fathom the amount of work necessary to update the packages, it may be wise to wait with that part a bit. All of this could be sooooo easy, if the bean counters at Atmel had seen the light. Apparently that's another case of 'why we're still using windows' and 'irrelevant market share'... .. but now it compiles my code ;-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Did not do anything with the toolchain for the last 6 months or so. Robert, would you want to help maintaining the toolchain yourself? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It is GCC version 4.3.5 with some additional patches. Could you please test the new package? You find it on https://build.opensuse.org/package/show?package=cross-avr-gcc&project=home%3Aarphen%3Abranches%3ACrossToolchain%3Aavr Download the RPM for your openSUSE version and install it. If it works well, please let us know. If it does not, report us the bugs. We hope to get the new package in the CrossToolchain:avr repository soon. Thanks, Simon -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I appreciate the effort. Speaking as a member of the Arduino community many thanks for making this work for all of us. I've tested these packages provided: avr-libc 1.7.1-1.1 cross-avr-binutils 2.19.1-33.1 cross-avr-gcc 4.3.5_20100125-29.1 vs. (via avrfreaks.net) GNU size (GNU Binutils) 2.20.1.20100303 avr-gcc (GCC) 4.4.3 avr-libc 1.7.1 So far I've successfully compiled code for ATmega168 and ATtiny24 chips. It seems to work as far as I can tell (no error messages at least). Code size is smaller with the 4.3.5 version of avr-gcc. However compiling for the 4313 still fails. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
