When trying to build nodejs (v6.9.1) on CentOS6, `make` got an error.
\nIt requires gcc and g++ 4.8 or later, but CentOS6's gcc is 4.4.7.<\/p>\n

node-v6.9.1\/BUILDING.md<\/p>\n

Prerequisites:<\/p>\n

* `gcc` and `g++` 4.8 or newer, or
\n* `clang` and `clang++` 3.4 or newer
\n* Python 2.6 or 2.7
\n* GNU Make 3.81 or newer<\/p><\/blockquote>\n

So I decided to install gcc and g++ 4.8 or later with scl.<\/p>\n

$ sudo yum install centos-release-scl\r\n$ sudo yum install scl-utils\r\n$ sudo yum install devtoolset-4-gcc devtoolset-4-gcc-c++ devtoolset-4-binutils\r\n$ scl enable devtoolset-4 bash\r\n$ gcc --version\r\ngcc (GCC) 5.2.1 20150902 (Red Hat 5.2.1-2)\r\nCopyright (C) 2015 Free Software Foundation, Inc.\r\nThis is free software; see the source for copying conditions.  There is NO\r\nwarranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.\r\n<\/pre>\n
There are devtoolset-3 and devtoolset-4. I installed devtoolset-4.
\nI installed only gcc, g++ and binutils necessary for building nodejs, because it is massive when installing all with devtoolset-4.<\/p>\n
$ scl enable < collection1> [< collection1> ...] bash\r\n<\/pre>\n
This makes bash start with the environment where the installed collection can be used.<\/p>\n
To enable software collections for users after reboot, create under \/etc\/profile.d with the following content.<\/p>\n
$ cat \/etc\/profile.d\/enabledevtoolset-4.sh\r\n#!\/bin\/bash\r\nsource scl_source enable devtoolset-4<\/pre>\n
https:\/\/access.redhat.com\/solutions\/527703<\/a><\/p>\n
Caution<\/h2>\n
When devtoolset-4 is enabled, sudo is sometimes broken such as `sudo -i` results in error.<\/p>\n
$ sudo -i\r\n[sudo] password for foo:\r\n\/var\/tmp\/sclXXXXXX: line 8: -i: command not found\r\n<\/pre>\n
https:\/\/bugzilla.redhat.com\/show_bug.cgi?id=1319936<\/a><\/p>\n
In such cases, you can use `\/usr\/bin\/sudo` explicitly.<\/p>\n","protected":false},"excerpt":{"rendered":"
