Move the warning to an error as we have been promising would happen in
this release.

Oh. This has broken my U-Boot build/test system. I guess it's entirely
my fault for interpreting the "2018.01" warning as "you'll need to fix
this in Jan 2018", not "you'll need to fix this as soon as development
starts for 2018.01":-(
Is there a reason for requiring such an extremely new gcc, as opposed to
simply something not ancient? For example, no LTS version of Ubuntu
packages a compiler that's new enough to build U-Boot now:-(

I'm tagging v2018.01-rc1 later today, so I think this is about the time
to enforce the warning.

There's always the Free Electrons toolchains, as well as Linaro. And
yes, we've been having size problems and having to play various games to
allow for older gcc versions to still fit things in. GCC-6 is where
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 was resolved and we
get a lot of space saved, and a number of platforms simply won't work
with older.

Yes, all my U-Boot tbot builds tonight failed :-(

Yes, I have the AT91 based smartweb board, for which the SPL have to fit
into 4k sram (is in my weekly tbot builds).

Just looked at:
http://toolchains.free-electrons.com/
for example the stable toolchains for arm are gcc 5.4.0 based.
Ok, there is the "bleeding-edge" ... gcc 7.2.0 based...
Hmm.. linaro has 7.2.0 in its latest release ... so, currently only
linaro toolchain can be used for compiling U-Boot ?
setup the tbot tests with linaro toolchain:
https://releases.linaro.org/components/toolchain/binaries/7.2-2017.11/arm-linux-gnueabi/
Ok, build for corvus board works, see:
http://xeidos.ddns.net/tests/test_db_auslesen.php#528
but for the smartweb board I get:
LD spl/drivers/built-in.o
LD spl/u-boot-spl
arm-linux-gnueabi-ld.bfd: u-boot-spl section `.u_boot_list' will not fit in region `.sram'
arm-linux-gnueabi-ld.bfd: region `.sram' overflowed by 16 bytes
make[1]: *** [scripts/Makefile.spl:343: spl/u-boot-spl] Error 1
make: *** [Makefile:1394: spl/u-boot-spl] Error 2
hs at pollux [ 7:48:49] ttbott>
:-(
Full log:
http://xeidos.ddns.net/tbot/id_529/tbot.txt
This build worked last week with gcc 4.9.2, see
http://xeidos.ddns.net/tbot/id_515/tbot.txt

Heiko

GCC-6 matches the definition of “not ancient”.
We’ve just gone to phase 3 on GCC-8 a few weeks back, so GCC-6 will be 2 years old in April.
Usually, toolchains for embedded targets are maintained on a “stable” and “one behind-stable” basis.
Which already makes GCC-6 the oldest toolchain that will receive backports. For example, Linaro now has GCC-6 and GCC-7 trees and will retire the GCC-6 tree once GCC-8 becomes stable (i.e. once 8.1.0 comes out in about April).
> For example, no LTS version of Ubuntu packages a compiler that's new enough to build U-Boot now:-(
I recommend crosstools-ng for situations like this… in fact, I recommend crosstools-ng for any setup.
Building a [target]-elf toolchain really doesn’t take long.
Best regards,
Philipp.

I've been using gcc 7.x in Fedora since the beginning of the year to
build u-boot

I guess it's time, really, to make buildman fetch from the free
electrons toolchains instead of the old kernel.org ones, can you take a
pass at that? Thanks!

I disagree here. LTS Ubuntu (as an example of one reasonable distro that
one might use) is only released every 2 years, and multiple of them are
fully supported in parallel (so older releases are also reasonable to
use). A 2-year-old toolchain is just old enough that one single LTS
distro release /might/ have picked it up (in this case, this hasn't
happened yet). To me, "not ancient" means "not 5 years old or more",
where "5" is somewhat arbitary and could easily be 5-10 say, but
certainly not a very small number like 2.
FWIW, I managed to get my systems running using Linaro gcc-7.2.1
2017.11. However, the process was annoying since the older internal
U-Boot branches we still support don't support anything /newer/ than
gcc-5 (even for releases only about 1.5 years old; U-Boot jumped forward
on compilers extremely fast with little overlap in support), so I had to
make my system use a different toolchain for different builds:-( At
least I have the infrastructure in place for this for next time.
