>Description:
Hi,

trying to get https://github.com/rumpkernel/wiki/wiki/Tutorial%3A-Building-Rumprun-Unikernels running inside OpenBSD (in VirtualBox 5 on Windows 7 64bit). However is not working with either default gcc or newer one from packages. Antti pointed this one out https://github.com/rumpkernel/rumprun/issues/14 which was exactly what I get.

So instead I followed his advice from here https://github.com/rumpkernel/wiki/wiki/Howto%3A-Set-up-a-Rumprun-toolchain-in-Mac-OS-X , downloaded sets from http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201605170140Z/source/sets/{share,gnu,sys,}src.tgz and tried build, first with no CC defined (default gcc), then with CC=egcc (from packages). But always getting same error which you can see here http://pastebin.com/UVt31Z45

Tried that already 6 times and still exactly same result.

$ gcc -v

$ egcc -v

Right now not sure if it is problem in src-netbsd, OpenBSD itself, cooperation of those two, load on VM and/or host or build.sh fail

Not right now to me.
