Hello,
I'm trying to remove an element from DISTRO_FEATURES (specifically
"ld-is-gold"), but I am unable to find the right spot to do it. The
distribution we're using (Angstrom, as it happens) sets this in
conf/distro/angstrom-v2012.x.conf. My machine configuration is the
wrong spot to modify DISTRO_FEATURES, since it will be processed
first. local.conf is not working, too.
So could anybody please tell me where I need to put my
DISTRO_FEATURES = "${@'${DISTRO_FEATURES}}'.replace('ld-is-gold', '')}"
so it applies for the build?
Regards,
Thilo

Unfortunately such hacks only work for variables that are not set within the distro configuration, which is applied after local.conf. Ultimately you shouldn't really do this. If you want to change distro policy then you really ought to have your own distro configuration, or try to work with the existing distro to fix whatever problem exists.

It's a backwards compatibility thing: we're bound to gcc-4.5 (we have kernel build issues with newer gcc versions; we're nailed to linux-2.6.37 thanks to lack of support by Texas Instruments) which fails to detect the correct version of binutils GOLD (LD would work) and therefore misses critical features which break the build later on. I won't, however, try to convince the Angstrom guys to further support ancient toolchains and make gold optional again just because of TI's laziness. I'll try to set up a minimal config for a distribution based on Angstrom, then, so I can fix up DISTRO_FEATURES. Thanks for your help, Paul.

I think you are severely misinformed! Above issues (binutils-2.20/gcc-4.5 requirement and gold ld problem with Thumb) were already fixed. I've been testing the builds with gcc-4.6 and binutils-2.22 for few weeks and even gcc-4.7 with gold linker since last week. I don't know what layer you are using, but you may need to update, if you are using meta-ti. Otherwise, if your platform is not directly supported by meta-ti, please send the bug report with the error message to meta-ti mailing list and I'll try to address it. As of linux-2.6.37 for your specific platform - this one I can't help with, you would need to talk to your TI rep from the division that makes the platform and convince them to provide support for newer kernels. -- Denys ^ permalink raw reply [flat|nested] 13+ messages in thread

You're right, gcc-4.7 works well in the current setup. gcc-4.5, however, does not detect the right binutils version with the GOLD linker. GOLD version output is: GNU gold (GNU Binutils 2.22) 1.11 The configure logic of gcc-4.5 would extract "1.11", not "2.22", for the version number. Since Binutils 1.11 is ancient, some features of gcc-initial are not set up correctly (gcc thinks the linker does not support the "hidden" attribute). This breaks the build of eglibc-initial later on. I overslept the whole thing and I guess I'll just provide a patch to gcc-4.5's configure so the GOLD linker version is detected correctly instead of setting up my own distribution config. > I don't know what layer you are > using, but you may need to update, if you are using meta-ti. meta-ti does not provide any toolchain anywhere. I have a toolchain issue. The issue is with gcc-4.5 from meta-oe/toolchain-layer in combination with binutils-2.22 from openembedded-core/meta/recipes-devtools/. Just in case you're curious, our layer structure is documented here: <https://github.com/DFE/HidaV/wiki/Hidav-oe-layers>. > Otherwise, if your platform is not directly supported by meta-ti, please send > the bug report with the error message to meta-ti mailing list and I'll try to > address it. Which meta-ti mailing list are you talking about? There seem to be many: this one, the arago lists, yocto-ti, ... And then again, it's a toolchain issue (see above); meta-ti doesn't have toolchains. > As of linux-2.6.37 for your specific platform - this one I can't help with, > you would need to talk to your TI rep from the division that makes the > platform and convince them to provide support for newer kernels. I know, it's OK. We talked to TI a lot for quite a while, but our realistic assessment from our TI experiences is that they'll never do it. There are still a lot of issues with their old 2.6.37 kernel, TI continually keeps breaking things. They don't have proper issue trackers or mailing lists for communication with their developers. From the reps and FAEs we'd get the occasional empty promise, but that's it. Personally I think we went wrong with buying TI in the first place.

Well, while still being an ugly hack, this should still be possible using local overrides... I.e. VAR_local in OE or VAR_forcevariable in OE-core/Yocto.

Actually it would be easiest for me if the last 5 lines of https://github.com/Angstrom-distribution/meta-angstrom/blob/master/conf/distro/angstrom-v2012.x.conf would not be DISTRO_FEATURES += "${LDISGOLD}" LDISGOLD_arm = "ld-is-gold" LDISGOLD_x86 = "ld-is-gold" LDISGOLD_x86_64 = "ld-is-gold" LDISGOLD = "" but instead be DISTRO_FEATURES += "${LDISGOLD}" LDISGOLD_arm ?= "ld-is-gold" LDISGOLD_x86 ?= "ld-is-gold" LDISGOLD_x86_64 ?= "ld-is-gold" LDISGOLD ?= "" But anyways, I decided to fix the gcc-4.5-cross-initial build.

The latest angstrom is built around systemd which requires a 2.6.38 or better kernel. > I've had to reluctantly revert back to oe-classic and angstrom 2011.03. > Any hints on getting oe-core/Angstrom-v2012x working with a 2.6.37 kernel would be great. Angstrom uses linux-libc-headers-3.2 for user space ABI. It's a rather dangerous hack, but it enables you to use 2.6.37 with a state of the art user space. If you're curious just take a look at <https://github.com/DFE/HidaV>, that's our layer stack. The wiki has some documentation, too: <https://github.com/DFE/HidaV/wiki/Hidav-oe-layers>. Basically we use everything from meta-ti, meta-oe + meta-angstrom, and oe-core (let's not talk about meta-java ;) ). We just stick it together in meta-hidav, and so far angstrom-v2012.x works for us.
