Trying to install C++ from Devtoolset-3 to my CentOS6 system I've ran into dependencies problem:

bash-4.2# yum install devtoolset-3-gcc-c++
Loaded plugins: fastestmirror

You could try using --skip-broken to work around the problem

As for me it looks like a bug: SCL should contain updated packages for that libs... but maybe I've missed smth?

Answer 1

libmpfr.so is available from CentOS repository, but it is only 32bit version (I guess that is the case even for other mentioned packages).

There is bug #1312338 filled for this issue. From the comment it looks like issue with CentOS repositories. There is related bug #1254798 about missing ix86 (32bit) builds in the SCL, which might have solve your issue, if you would install this version.

I am afraid I can't help more, then guide you to these bugs, where you can ask for more details. Or you might try to report directly to CentOS if it is related only to CentOS.

As a workaround, you might give a try to copr repo with devtoolset, maybe with the dependencies.

Side question: Do you have enabled related software collections, as noted on the SCL page, section "Related software collections"?
