为 CentOS 安装过时的 Devtoolset 集合

Question

At present time Devtoolset-5 (and earlier) cannot be istalled from Software Collection Repository (centos-release-scl) using yum (only Devtoolset-6 and 7 are available). Nevertheless, this collection can be downloaded as a list of rpm-packages. Is it possible to enable such EOL collections for yum , or maybe there is another way to install them correctly?

Answer 1

There was no DTS 5 release. It was skipped to align the DTS version with the GCC major release, once GCC switched to a yearly increasing version number.

DTS versions 3 and 4 are available from the centos-release-scl repository.

Answer 2

While Devtoolset-3 and 4 are located on the Centos mirror site , yum will not be able to find them as they were not included in the repodata on the site. These were probably excluded because they are EOL (end-of-life), and have dependency bugs ( Bug 1410152 ). Try using the older Devtoolset-3 packages here, which do not have the dependency issues:

If you really want the packages from the centos.org site, I went with wget to download all the RPMs, then recreated a local yum repo. However, you'll see the dependency issues and yum install devtoolset-3 will fail.

$ wget -r -p -e robots=off --directory-prefix="/mnt/local-devtoolset3-repo" --recursive --no-clobber --no-parent http://mirror.centos.org/centos/6/sclo/x86_64/rh/devtoolset-3/
$ sudo yum install createrepo
$ cd /mnt/local-devtoolset3-repo
$ createrepo --database .

Answer 3

您可以通过以下方式安装过时的 devtoolset-3：

sudo yum --obsolete install devtoolset-3
