Re: [scl.org] SCL devtoolset on arm64/aarch64



Hi Honza,

thank's for the reply!

You are right, I was searching for devtoolset-6 for arm64.
On another mailing list I already got the hint to use the packages from buildlogs.centos.org
(https://buildlogs.centos.org/centos/7/sclo/aarch64/rh/devtoolset-6/).

As I had to use g++ 4.9 or 5.x back then (the code base was not ready for g++ 6.x),
I ended up using a self-built g++ 5.4 (with -D_GLIBCXX_USE_CXX11_ABI=0 to be able
to link against pre-built CentOS libraries).

I just wanted to give it a try and use your instructions to install devtoolset-6.
However, I ended up with the following error:

So I can confirm, that the packages are not there.

If you plan to make them available, then I'd be happy to test them.

Thanks,
Christoph
