bjam doesn't stop when it fails a build but compiles until the end (it does return an errorcode though). It would have a more make-like (and developer friendly) behaviour with the -q flag. From bjam --help: " * -q Stop at first error" Reproducible: Always Steps to Reproduce: 1. emerge boost (so that it fails somewhere ;)) 2. Have fun finding the failing part
That's a pretty good idea. Added to the ebuild without revision bump. Cheers.
