fuse4bsd on kfreebsd?


I just tried to get fuse4bsd[1] compiled on kfreebsd. Here's how far I
came and what I needed to get (not) so far.

  [1] http://fuse4bsd.creo.hu/

First I had to add some symlinks:

# ln -vis kfreebsd-source-8.1/sys /usr/src/sys
# ln -vis i386 /usr/src/sys/i686

I guess for a package, the source would be patched appropriately
instead of creating those symlinks.

I had to use freebsd-make from freebsd-buildutils since GNU Make
doesn't work (as in other places, too).

It fails with "make: don't know how to make fuse_kernel.h. Stop". This
file can be found in the fuse source package, but is not included in
the libfuse-dev binary package built from it. Probably solvable via a
wishlist against libfuse-dev.

With that file symlinked to fuse4bsd-hg/fuse_module/fuse_kernel.h, it
fails to build after a while with the following error message:

fuse_dev.c: In function `fusedev_clone':
fuse_dev.c:551: error: implicit declaration of function `unit2minor'

This seems to be a change in FreeBSD 8.x, other software (e.g. zaptel)
patched it by replacing "unit2minor(unit)" with just "unit" for
FreeBSD > 800062 or so.

Now it ends with quite some conflicting types:

fuse_vfsops.c:797: error: (Each undeclared identifier is reported only once
fuse_vfsops.c:797: error: for each function it appears in.)
*** Error code 1

I didn't manage to fix that yet.
