I doubt there was any good reason for it at all barring they got around to it. Compiling Nordic's C code is hardly taxing. I've been using various things including crossworks which has been on the v6 toolchain forever. Just use the latest

I've always wondered whether more recent versions of the GCC ARM toolchain can be used. I use the Makefile.posix in the Nordic SDK to tell me which one to install. Nordic appears to be pretty conservative about the toolchain, they only recently bumped from 2015q1 to 2015q3. I assumed there was a good reason for this?

anyway the official source for arm-none-eabi is developer.arm.com/.../downloads now and they are 2 years ahead and DO provide a 64 bit one. So @ladasky you should just download that one and get a newer compiler and 2 years of fixes, and be 64 bit.

I don't know if those are absolute dependencies. If those were actual dependencies - they should have been marked as such in the package specification.

from the readme ...

For 64 bit system, 32 bit libc and libncurses are required to run the tools.
In addition, if you want to use gdb python build (arm-none-eabi-gdb-py), you'd
install 32 bit python2.7. Please refer
answers.launchpad.net/.../2601

and why are you using a version 2 years out of date?

Try a direct link to the .deb launchpad.net/.../gcc-arm-embedded_6-2017q2-1~xenial1_amd64.deb

If you installed from the ppa - it should have pulled in the correct 64-bit build. Was there a release recently? I wonder if the maintainers had a packaging issue ...

.. or you can follow the build instructions and build your own 64bit one. Not sure you want to go down that rabbit hole.

the 'file not found' in that case usually refers to one of the dynamic library bits of the runtime which doesn't exist because you're not 32 bit. I just pulled in the arm-none-eabi toolchain from the source and indeed it is 32 bit. So you need to apt-get libc6-i386 to run it.

RK, I get "file not found." And Koniho (see below) figured out why.

Thanks Koniho. I do in fact have a 32-bit version of gcc-arm-none-eabi installed on my usual 64-bit Linux. Why haven't I had to deal with this before? I switched to 64 bit about 5 years ago. And why does Linux issue a "file not found" error? That's horribly misleading.

The front page at Launchpad says: "For Ubuntu 12.04/14.04/16.04/16.10 32/64-bit user, PPA is available at launchpad.net/.../ppa." I'm trying to follow those directions now. I don't know why they look unfamiliar.

It is also possible that the tool chain that is installed is 32-bit and you are running a 64-bit system. Check the output of:

file /usr/local/gcc-arm-none-eabi-4_9-2015q3/bin/arm-none-eabi-gcc

against the output of:

uname -a

what happens when you pull up a shell and type
