Can you add support for Travis? |
build-rr.sh
Outdated

There was a problem hiding this comment.
Can this bit somehow go into config.mk so that you don't need to keep typing "make kernonly" all the time in platform/hw?

I covered all the comments so far (thanks) and also fixed some other mistakes. I'll give the buildtests/Travis support a shot. |

Thanks. Please rebase your branch to clean up unnecessary commits and drop a note when you think it's ready to merge. |
Currently only supported for the 'hw' platform. This builds rumprun without any userland code (i.e. libc, app-tools), for custom builds that invoke rump kernel functions directly.

Added the -k flag to buildtests.sh as well; and rebased the code now. Ready to be merged from my side, once Travis is green. |

This will build the rump kernel bits and the platform code (i.e. librumpuser), but without libc or (as a consequence) app-tools. The motivation behind this is a use case where one invokes the rump kernel directly.
As there is no rumprun_base, the client code needs to provide the mainthread entry point invoked by the platform code. Linking also has to be done manually. This pull request contains some example code, showing how one could do this. Because there is no libc,
compiler_rtfrom the NetBSD tree is built if-kis used.Currently, only the
hwplatform is supported. I haven't found the time yet to fixxensupport, e.g.mini-os/types.hcurrently includes some userland headers.
