If you mean with pre-built binaries of the ODB compiler (and bundled
GCC), then the answer is no. This proved to be very fragile with GCC
often breaking in obscure ways due to changes in system headers.

We do plan to provide (as a general build2 mechanism) automatic
creation of distribution packages (.deb, .rpm, etc., could probably
also be plain .tar.gz) but those won't include bundled GCC (so the
result will only work on the same distribution/version). You can
already do this manually as shown here:
