Can't install arduino (missing avr-g++)

Postby rafaeltcc » Wed Nov 10, 2010 18:17

Hi,

Using latest Sabayon 5.4 KDE 64bits

equo install arduino warns me:

Missing avr-g++; you need to crossdev -s4 avr

I do as told:

crossdev -s4 avr

Everything is emerged all right, no error or warning, but reruning "equo install arduino" brings me the same warning. It seems as if avr-g++ hasn't been built...

Thanks a lot for any help.. For now I have to use a virtual machine with ubuntu to use my arduino...

eix -I avr && eix -I gcc

Hi, I had already tried that. I am in the same situation of the last one who posted in the bug report...

USE="-openmp" crossdev -s4 avr

is adequate to get a working avr-gcc, but not g++.


No warinng, no error, but avr-g++ isn't build or recognized...

I believe I had the same problem.

For me it helped to first change manually the use flag for crossdev to -nocxx at /etc/portage/package.use, remove any repeated use flags from the line (there were several, apparently after multiple runs of the script) and then use

sudo USE="-nocxx" crossdev -s4 -t avr

as instructed by Mr. Chau at the other forum.
