linking errors in rumprun-bake when building against newer netbsd sources #129

Open fabianfreyer opened 5 years ago

fabianfreyer commented 5 years ago

Build process

I Built rumprun with GCC 8.2.0 after applying #127. I also had to apply #128, as NetBSD seems to have dropped the const qualifier on _lwp_park in https://github.com/NetBSD/src/commit/ff4eff81e3b6454b848a46b64db75576014f1e1b.

Updating src-netbsd

I used buildrum.sh/checkout.sh to generate an updated src-netbsd repository at https://github.com/fabianfreyer/rumpkernel-src-netbsd/tree/all-src. The CVSDATE of the checkout was

NBSRC_CVSDATE="20180401 0436UTC"

Note: I had to add --allow-unrelated-histories to the git merge commands, since git >= 2.9 won't merge those otherwise (not sure if I should open a PR for this?):

Hi,

May I suggest you to read that thread the following thread in the mailing list? https://www.freelists.org/post/rumpkernel-users/How-to-update-srcnetbsd-status-of-rumpkernel-and-related-questions

I think some parts are relevant.
