[avr-gcc-list] avr-gcc toolchain problem on x86-64 system

[Ken Lauffenburger]

Hello,

I'm a newbie to this list, so please forgive me if this is an elementary problem.

I recently built the avr-gcc toolchain on my Gentoo AMD-64 system.  I used the following command to build it:

crossdev --target avr

It seemed to work fine.  However to test the installation I downloaded two different projects from the avrfreaks site and tried to build them.  I ran into the same issue with both of them:

avr-gcc (GCC) 3.4.6 (Gentoo 3.4.6, ssp-3.4.5-1.0, pie-8.7.9)

/usr/libexec/gcc/avr/ld: cannot open linker script file ldscripts/avr5.x: No such file or directory

So apparently avr-ld can't locate the ldscripts/avr5.x file.

Checking out the subdirectory tree where avr-gcc tools are stored, I find the following:

So there is a file avr5.x in /usr/lib/binutils/avr/2.16.1/ldscripts/ and the symbolic link ldscripts in /usr/x86_64-pc-linux-gnu/avr/lib/ points to it.

Apparently the search root for the ldscripts directory in avr-ld is something other than ../../../lib/binutils/avr/2.16.1/ldscripts/ ?

I'm guessing I have a wrong or missing symbolic link somewhere in my toolchain.

Can anyone help?

Thanks.

BTW, here are some other symbolic links relevant to the avr toolchain:
