Generic Makefile for CMT projects

History

CMT is a tool that moves away from the de-facto standards in the Open Source and Linux communities, making the usage of standard tools (like eclipse) difficult to use. In some cases the tools are configurable enough to allow, with some efforts, to enable them to build our software.

Instead of configuring different tools to understand CMT, we can take another route: add a layer of wrapping around CMT that adheres to the santards mentioned above, for example by a Makefile that embed calls to the cmt program.

I started to write such a Makefile avoiding as much as possible LHCb-specific conventions to have a single file that could be used in any CMT project to simply call "make" "make clean" and have the project built in the correct way (you should know that the safest way to build a CMT project iis a call to cmt broadcast cmt make from the "main" package of the project). Along the way I discovered that the Makefile I was writing allowed to build a project using several processes in a way that has never been possible even combining tbroadcast and cmt make -j.

After some time, the generic Makefile was included in the project LbScripts

How to get it

You may not have noticed, but you already have it. It is automatically added to each new local project created with SetupProject --build-env (or the shortcut setenvProject) and to each project checked out with getpack --project.

Actually, the Makefile created points simply to the one in the version of LbScripts you are using, so that you will automatically pick up the new features whenever a new release of LbScripts is put in production.
