I don't have any gcc right now on my machine. my Linux version is: Red Hat Enterprise Linux Server release 7.4 (Maipo) can someone help me and give me instructions from the beginning to the end how to do this properly? thank you very much.

Answer 1

yum install centos-release-scl-rh
yum install devtoolset-3-gcc devtoolset-3-gcc-c++
update-alternatives --install /usr/bin/gcc-4.9 gcc-4.9 /opt/rh/devtoolset-3/root/usr/bin/gcc 10

Answer 2

For installing the system compilers gcc, g++, the install command is # yum install gcc-c++ → Provides version 4.8.5 : /usr/bin/{ gcc, g++ }.

Other options: 1. gcc53-c++-5.3.0-1.el6.x86_64.rpm → https://drive.google.com/file/d/0B7S255p3kFXNRm9FVnZYUnhyZzg/view?usp=sharing&resourcekey=0-1N6zQa6Sbl_WycG1O9I7JA : Download and install : # cd Downloads/ && yum install ./gcc53-c++-5.3.0-1.el6.x86_64.rpm ..... Provides /usr/bin/{gcc53, g++53}.

2. The devtoolset´s : https://www.softwarecollections.org/en/scls/rhscl/devtoolset-6/ → # yum-config-manager --enable rhel-server-rhscl-7-rpms

Install gcc, g++ version 4.9.2 : # yum install devtoolset-3-gcc-c++

Note : You can have as many gcc/g++ versions as you want, installed at the same time. ( The system compilers are a must.)

RHEL comes with preconfigured repo, you can search for the desired packages and install them using yum package manager.

To do so, first run ( to search gcc )

$ sudo yum search gcc 

which will show you a list of available packages with the matching name

============================ Name Exactly Matched: gcc =============================
gcc.x86_64 : Various compilers (C, C++, Objective-C, ...)
gcc.x86_64 : Various compilers (C, C++, Objective-C, ...)
gcc.i686 : Various compilers (C, C++, Objective-C, ...)
=========================== Name & Summary Matched: gcc ============================
gcc-c++.x86_64 : C++ support for GCC
gcc-c++.i686 : C++ support for GCC
gcc-gdb-plugin.x86_64 : GCC plugin for GDB
gcc-gdb-plugin.i686 : GCC plugin for GDB
gcc-gdb-plugin.x86_64 : GCC plugin for GDB
