[CentOS-announce] Announcing release for Developer Toolset 3 on CentOS Linux 6 x86_64 SCL

[Honza Horak]

I am pleased to announce the immediate availability of Developer Toolset 
3 on CentOS Linux 6 x86_64, delivered via a Software Collection (SCL) 
built by the SCLo Special Interest Group 
(https://wiki.centos.org/SpecialInterestGroup/SCLo).

QuickStart
----------
You can get started in three easy steps:
$ sudo yum install centos-release-scl
$ sudo yum install devtoolset-3-toolchain
$ scl enable devtoolset-3 bash

At this point you should be able to use gcc and other tools just as a 
normal application. Examples of commands run might be:
$ gcc hello.c
$ sudo yum install devtoolset-3-valgrind
$ valgrind ./a.out
$ gdb ./a.out

In order to view the individual components included in this collection, 
including additional development tools, you can run:
$ sudo yum list devtoolset-3\*

About Software Collections
--------------------------
Software Collections give you the power to build, install, and use 
multiple versions of software on the same system, without affecting 
system-wide installed packages. Each collection is delivered as a group 
of RPMs, with the grouping being done using the name of the collection 
as a prefix of all packages that are part of the software collection.

The collection devtoolset-3 delivers version 4.9.0 of the GNU Compiler 
Collection, GNU Debugger, and other development, debugging, and 
performance monitoring tools as RPMs.

However, in comparison to Developer Toolset 3 collection as available 
for CentOS 7, this collection does not include Eclipse development 
platform, because SCLo SIG does not have enough resources for rebuilding 
many depended packages.

The SCLo SIG in CentOS
----------------------
The Software Collections SIG group is an open community group 
co-ordinating the development of the SCL technology, and helping curate 
a reference set of collections. In addition to the Developer Toolset 
collection being released here, we also build and deliver databases, web 
servers, and language stacks including multiple versions of PostgreSQL, 
MariaDB, Apache HTTP Server, NodeJS, Ruby, Python and others.

Software Collections SIG release was announced at 
https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html

You can learn more about Software Collections concepts at: 
http://softwarecollections.org
You can find information on the SIG at 
https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto 
get involved and help with the effort.

We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: 
https://www.centos.org/community/calendar), for an informal open forum 
open to anyone who might have comments, concerns or wants to get started 
with SCL's in CentOS.

Enjoy!
