(with the name replace to 7.4.0)
but when i run the make command i det the following error:

We ship numerous gcc versions as part of th e devtoolset packages. Does it need to be exactly 7.4.0? What we ship are the following:

Code: Select all

[root@centos7 ~]# yum list dev\*gcc
Loaded plugins: priorities
Available Packages
devtoolset-3-gcc.x86_64                                    4.9.2-6.el7                                      centos-sclo-rh
devtoolset-4-gcc.x86_64                                    5.3.1-6.1.el7                                    centos-sclo-rh
devtoolset-6-gcc.x86_64                                    6.3.1-3.1.el7                                    centos-sclo-rh
devtoolset-7-gcc.x86_64                                    7.3.1-5.15.el7                                   centos-sclo-rh
devtoolset-8-gcc.x86_64                                    8.2.1-3.el7                                      centos-sclo-rh

So yum install centos-release-scl then yum install devtoolset-7-gcc.x86_64 and use `scl enable devtoolset-7 bash` to get a command prompt set up o run it.

I would say:

Code: Select all

yum install centos-release-scl-rh
yum install devtoolset-7-toolchain
scl enable devtoolset-7 bash
* The centos-release-scl and centos-release-scl-rh have different subsets of SCL packages
* The *-toolchain pulls in all devtoolset packages that one needs for compiling from commandline. Not sure whether the *-gcc does.
* The scl environment is for whole devtoolset-7; the devtoolset-7-gcc does not have separate config.

I thought you did know already:

Code: Select all

$ which g++
/usr/bin/g++  # By default we see system's g++ 4.8.5

# When we start a separate bash session with different environment:
$ scl enable devtoolset-7 bash
$ which g++
/opt/rh/devtoolset-7/root/usr/bin/g++  # a different g++ is visible
# we can compile in this shell
#
$ exit
exit
# After that bash session ends we are back in bash that sees the 4.8.5
$ which g++
/usr/bin/g++
