I have attached two patches that can be used to update to gcc 4.5.2.

Installation

patch-avr-config-unknown-mcu.diff patches gcc. It needs to go into $(port dir avr-gcc)/files. Something like this:

sudo cp ~/Downloads/patch-avr-config-unknown-mcu.diff $(port dir avr-gcc)/files

patch-avr-gcc-update-452.diff updates the portfile for gcc 4.5.2. Apply with something like:

cd $(port dir avr-gcc)
patch -p0 < ~/Downloads/patch-avr-gcc-update-452.diff

Background

For the background of patch-avr-config-unknown-mcu.diff, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45261.

Basically, gcc doesn't return with an error if it encounters an unknown MCU. This breaks the configure step of avr-libc.

Caveats

I have removed the other patches for avr-gcc without really understanding them. YMMV

What needs to be done to get Lars patches into trunk? They seem to be fine.

BTW: The patch patch-avr-config-unknown-mcu.diff is not needed anymore from gcc 4.5.3 onwards. See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45261. It is fixed in gcc trunk revision 170536.

I've created a patch to update current trunk version of avr-gcc 4.6.2: See #33107. Please also update to latest avr-libc since the older version won't compile with gcc 4.6.2. See #33106.

comment:15 Changed 9 years ago by lars@…

If I could, I'd close this ticket and link to #33107.

gcc 4.6.2 fixes at least one annoying bug (wrong const warnings for PROGMEM placed constants when using C++) over 4.5.2

(But here we are, ghosts whispering to each other in this deserted place.)
