Thanks to all who responded, makes perfect sense now.

Great, that seems to do the trick! (actually, I just loaded the linux64
kmodule, did not try to apply the patch). Thanks!

Looks like the poudriere/common.sh needs this patch.

That should be linux_enable="YES" in /etc/rc.conf, not USE_LINUX.

The only thing you need on the host is to have the linux kernel module loaded.  
(You don't need to have any Linux packages installed there.)  The default 
setting in /usr/local/etc/poudriere.conf is to have NOLINUX=yes commented out, 
i.e., Linux support in Poudriere is enabled unless you explicitly disable it.

The easiest way to load the linux kernel module on the host for use with 
Poudriere is to add it to the "kld_list" setting in /etc/rc.conf, e.g.,

kld_list="linux"

To build a package, its dependencies need to be installed and on
installation some packages may need to run certain commands and for
linux packages these commands may be linux programs.  So, yes, if you
need to build linux packages the build host should have USE_LINUX=yes
in /etc/rc.conf.

qmake, moc, various utilities for maintaining Qt object registries... there
will be a lot of build tools, and you would need to force them to build
native instead of linux if you wanted to get away with not having the
linuxulator installed. (This will be hard if they are part of another build
that needs to be linux.) Same applies to gtk and dependents. And their
respective upstreams likely have no interest in what amounts to a
cross-compilation setup: too much difficult (and difficult for them to
test) work, very little demand.

For example, your log includes building qdoc3. It is likely to be used in build 
process of other Qt packages.

I rhink the host wouldn't need the linuxolator for building the Linux

Does building linux packages under poudriere require linux compatibility emulation?

[Mark Martinec]

When building packages under poudriere on 11.0-RELEASE-p7 (from a 
command
line in a terminal window) I'm noticing occasional streams of 
diagnostic:


  ELF binary type "3" not known.

which seem to be related to building some linux packages (example below,
parallel builds). Poudriere still reports success for these builds.

The host where poudriere is running does not have linux.ko loaded.

Does building such packages really require linuxilator configured
on the build host ???
