arm64 architecture
It would be really useful to support other architectures, especially the arm64.
I tried a quick hack - in Dockerfile (for 7-toolchain & centos7) change standard x86_64 arch base image from centos:centos7 to arm64v8/centos:centos7, and then run make build TARGET=centos7 VERSION=7-toolchain, build have been going for short time and then failed trying to fetch repodata from wrong url (http://mirror.centos.org/centos/7/sclo/aarch64/rh/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found) - please see bellow the full log output.
Have been looking around, and found that this http://mirror.centos.org/altarch/7/os/aarch64/repodata/repomd.xml url might be the right one, but this would need to confirmed.

One of the configured repositories failed (CentOS-7 - SCLo rh),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=centos-sclo-rh ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable centos-sclo-rh
or
subscription-manager repos --disable=centos-sclo-rh
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=centos-sclo-rh.skip_if_unavailable=true
failure: repodata/repomd.xml from centos-sclo-rh: [Errno 256] No more mirrors to try.

@khardix What is a status of CentOS infrastructure for alternative architectures? Is it even possible to rebuild SCL for arm64?
@omron93 Yes, it should be possible to rebuild a SCL for aarch64/ppce64le. It is not enabled by default, however, and it must be requested via ticket in https://bugs.centos.org.
Currently the only collections built in this way are devtoolset-6 and -7. The link found by @pbukva should indeed be the correct one.
Currently the only collections built in this way are devtoolset-6 and -7.
And how it can be accessible? See log in https://github.com/sclorg/devtoolset-container/issues/31#issue-326890381
Ah, sorry, I failed to spot that the path in OP is different than the one I looked into :blush:. The correct baseurl is http://mirror.centos.org/altarch/7/sclo/aarch64/rh/.
I'm not aware of any prepared repo configuration in lieu of centos-release-scl* package for alternative architectures, so the repository must probably be added manually.
@pbukva So possible changes to be able to build this image for aarch64 are:
- change base image
- instead of https://github.com/sclorg/devtoolset-container/blob/master/7-toolchain/Dockerfile#L23-L24 have
RUN yum-config-manager --add-repo=http://mirror.centos.org/altarch/7/sclo/aarch64/rh/ && \
Please comment if it works. Thanks.
I had to move fast in order to test stuff on arm64 arch, so I switched to ubuntu:18:04 image & installed dev toolchain there quickly.
But I will return to this later, probably this by end of this week, and test the suggested solution.
Disable centos-sclo-rh && Enable centos-sclo-rh-testing? URL in centos-sclo-rh is incorrect even if in the host machine of aarch64.
Yup, it does not work.
Tried with what @omron93 suggested and it still fails.
Host is aarch64.

@samip5 Just an idea looking at the logs (did not try it out myself) - removing the yum -y install centos-release-scl part might help.
