Trying to compile fuse fs for ext4



Hi,

I’m pretty new to NetBSD, and I have some ext4 partitions that I would like to 
access
from my NetBSD installation.

So I found a fuse filesystem for ext4 (https://github.com/gerard/ext4fuse) and
I’m trying to compile it against librefuse. I’ve installed wip/libexecinfo from
pkgsrc, patched the Makefile (patch attached to this mail) and built a binary,
but when I try to mount a fs, I get a core dump :

# ./ext4fuse /dev/wd0i /f/disk
[1]   Abort trap (core dumped) ./ext4fuse /dev/wd0i /f/disk

I attach to this mail the output of the build, and a traceback.


If you think of any other way to acces ext4 fs from NetBSD, feel free to tell me
:)

Any help to build and use successfully this fuse filesystem would be great :)
