devtoolset-7 also provides newer versions of lots of supporting debug and performance tools like gdb.

They (RH or Centos) also provide containerised versions of the build tools and the performance tools.

There is also a tech preview of the llvm-toolset, admittedly at clang v4 but still able to build those compatible binaries.

Note that you want to build using a host that is lower or same version as your minimum target version.

e.g. toolset-7 on host centos v6.7 will create bins compatible with 6.7, 6.9 and 7.x If your host is say centos 7.2 toolset-7 builds are only guaranteed to be compatible with v7.2+ targets.

Redhat's documentation is really good (and you can even get a free developer login to access more resources).

Also note that Centos provides similar options to RHEL.

The only downside is I don't think you can use the new ABI variant of CXX LIB as the ABI isn't compatible with older compilers like the default Centos gcc 4

Not really a problem as you can still use the C++11/14/17 features, just a few items are incompatible (such as list::size() still being O(n) and not const time, or strings still being COW)

https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/ (Lots of other tools/langs etc there too like Go,Rust,Python3 and lots of database updated versions etc.)

Not sure if you need to have a developer account, but an example of the documentation: https://access.redhat.com/documentation/en-us/red_hat_developer_toolset/7/html/7.0_release_notes/dts7.0_release

I found this source very useful and doesn't has much SEO. It lists the most common errors you might encounter while using @UnitasBrooks great answer and I'm afraid it gets lost in the future.

This is the link to the original post

I will copy, paste it here (I faced the last problem and it fixed it, however I didn't try all the problems/solutions listed and you try it on your own risk)

Glibc installation

The GNU C Library, commonly known as glibc, is the GNU Project's implementation of the C standard library. My environment required glibc (version 2.14) and it took a bit of fiddling to get it to work, so hopefully this will save you some time.

0.Glibc Installation Dependencies

Bash: sh
Binutils: ar, as, ld, ranlib, readelf
Diffutils: cmp
Fileutils: chmod, cp, install, ln, mknod, mv, mkdir, rm, touch
Gcc: cc, cc1, collect2, cpp, gcc
Grep: egrep, grep
Gzip: gzip
Make: make
Gawk: gawk
Sed: sed
Sh-utils: date, expr, hostname, pwd, uname
Texinfo: install-info, makeinfo
Textutils: cat, cut, sort, tr

1.Download installation package

http://www.gnu.org/software/libc/ for all versions.
http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz for version 2.14.

2.Compile and install

To avoid disturb current environment, compile and install this version separately by configuring prefix.

[root@localhost ~]# tar xvf glibc-2.14.tar.gz
[root@localhost ~]# cd glibc-2.14
[root@localhost glibc-2.14]# mkdir build
[root@localhost glibc-2.14]# cd ./build
[root@localhost build]# ../configure --prefix=/opt/glibc-2.14
[root@localhost build]# make -j4
[root@localhost build]# make install
[root@localhost build]# export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

3.To check glibc versions installed

root@localhost:~/intel64/runtime/glibc$ strings libc.so.6 | grep GLIBC
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_PRIVATE

4.Compiling errors

Error:

make[1]: *** No rule to make target /mnt/lfs/sourcenew/glibc-build/Versions.all', needed by/mnt/lfs/sourcenew/glibc-build/abi-versions.h'. Stop.

Solution:

sudo apt-get install gawk
sudo apt-get install texinfo

Error:

make[2]: *** [/mnt/lfs/sources/glibc-build/misc/syslog.o] Error 1

Solution:

make clean
make -j2 CFLAGS="-U_FORTIFY_SOURCE -O2 -fno-stack-protector"

Error:

/Downloads/glibc-2.14/build/elf/ldconfig: Can't open configuration file /opt/glibc-2.14/etc/ld.so.conf: No such file or directory

Solution:

:/opt/glibc-2.14/etc$ sudo sh -c "echo '/usr/local/lib' >> ld.so.conf" 
:/opt/glibc-2.14/etc$ sudo sh -c "echo '/opt/lib' >> ld.so.conf"

glibc-devel should be part of the base repo, you may have a some conflicts with your repos.

try disabling all the extra repos you added and try again.

You should also check yum Priorities plug-in which can prevent a 3rd party repository from replacing base packages, or prevent base/updates from replacing a 3rd party package.
