Hi Daniel,

This sounds more of a question for the CDT mailing list or forum.

Try it this way it should work. Change the location to point to the your
lttng-ust folder. Basically, every .configure folder should map to a
different CDT project. "Empty project" in this case means that it just
doesn't create source files for you. "Makefile Project with Existing
Code" does pretty much the same thing as a new project with Makefile >
Empty project but there's not Autotools equivalent.

Cloning the git.lttng.org lttng-ust master branch (for example) is easy, my problem is in getting the Autotools to kick in properly.  Eclipse's array of options is somewhat overwhelming; as a consequence I've managed to build userspace-rcu, but I didn't take notes and I can't seem to reproduce the method with lttng-ust.  Frustrating.

This *almost* works, with the console showing configure attempting to run and failing because bootstrap did not run ("Invoking autoreconf in build directory: /home/daniel/git/git.lttng.org/lttng-ust/  |  sh -c "autoreconf -i"  |  aclocal: couldn't open directory `config': No such file").  I can shell out to the directory, run bootstrap, then refresh the Eclipse project and pick "Reconfigure project" from the contextual menu.  I can't help but hope there's an easier, better way?
