I'm used to install packages on Debian/Ubuntu distributions, but now I need to install gcc
and g++
version 8.*. There is only version 4.* in CentOS repositories. What's the correct way to install them manually?
The default CentOS repositories contain a package group named Development Tools that contains the GCC compiler and a lot of libraries and other utilities required for compiling software.
CentOS 8 already comes with GCC 8.
On CentOS 7, you can install GCC 8 from Developer Toolset. First you need to enable the Software Collections repository:
yum install centos-release-scl
Then you can install GCC 8 and its C++ compiler:
yum install devtoolset-8-gcc devtoolset-8-gcc-c++
To switch to a shell which defaults gcc
and g++
to this GCC version, use:
scl enable devtoolset-8 -- bash
You need to wrap all commands under the scl
call, so that the process environment changes performed by this command affect all subshells. For example, you could use the scl
command to invoke a shell script that performs the required actions.
