[CentOS-devel] Ceph on arm32 - failing to compile devtoolset-8-gcc-8.3.1-3.1.el7.src.rpm

Ok, I missed an important part. I need version 8.3.1.3.1 the one in the 
rep is 8.3.1.3 :( So I have to compile it. I will give it a try. Or do 
you think there will be an updated package available soon?

Cheers,

Oliver
