I am pleased to announce the immediate availability of Developer Toolset 4 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-4-toolchain $ scl enable devtoolset-4 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-4-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-4\* 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-4 delivers version 5.2.1 of the GNU Compiler Collection, GNU Debugger, and other development, debugging, and performance monitoring tools as RPMs. 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! Honza SCLo SIG member
