Hi @dobryj !
As you probably know, multilib configuration is now in mainline GCC 7, so I completely removed the step which patches GCC to add that capability. This means that I also removed your big-endian variants or ARMv7-R. If you want to keep that, then please submit a pull request with updated patch that applies to GCC 7. Thanks in advance!

Hi FreddieChopin,
I'm new to this toolchain stuff.
Any idea why these errors (https://answers.launchpad.net/gcc-arm-embedded/+question/670151) happen when attempting to build the toolchain? I've applied the patch from here: https://gist.github.com/tgarc/3094325d61797d3ee0e3#gistcomment-2616981, and tried to build it but I got a string of "error: 'some var' undeclared (first use in this function) " complaints.
Thanks,
Saeed

Actually, I'm not even sure what's the difference between the patch in this link: https://gist.github.com/tgarc/3094325d61797d3ee0e3#gistcomment-2616981, and the one posted here. Aside from different toolchain versions.

@FreddieChopin @dobryj
Thanks for the reply. I re-applied the patch to [170314] and I was able to get the "installNative" and other packages as output. Was this patch tested on ARM Cortex R4 (specifically the Texas instrument's TMS570 boards)? Because when compiling with the patched-up toolchain I can't get my simple program to output anything to the serial monitor.
I've attached the patched build-bleeding-toolchain.sh and my Makefile in case you wanted to see.
script_and_Makefile.zip
I didn't port the patch to newer version 7 toolchain because I'm not sure how much changes has to be done for getting it to work.

This patch looks too aggressive. Current GCC compiler support big-endian very well. You need just compile big-endian version of multilibs. That is all.
See https://pastebin.com/z4AcpbDu
PS: we are using TMS570LC4357 and TMS570LS3137 big-endiand MCUs with GCC compiller more than 5 years. Problem is that discussion with maintainers of ARM feature of GCC is long story. Officially they don't want support something which they not able test and run testsuite.
