I got trouble compiling code for ARM based Arduino boards. All avr packages are correctly installed. The script I am using is compiling fine on Windows.
As I just recently started working with Arduino boards, I have to admit I lack experience in troubleshooting them. What I did find out through Google research is, that the fatal error - see logfile below - is somehow related to the avr-gcc package.
There are a lot of "elf32_x86_64" files in some /usr/share directory, but none with an "avr" phrase in the filename; don't know if this information is of any use.
Any ideas how to fix this?
