Build failed had to add -Wno-error to get it to build.

The build failed due to issues with linking perl symbols. Had to do this edit to make the build work:

python-xattr or python-pyxattr is required for ltfs_ordered_copy

https://github.com/LinearTapeFileSystem/ltfs/issues/334

attr -g ltfs.ltfs.startblock [srcfile]

gave nothing back but on ltfs-hpe it worked (ltfs_ordered_copy)

it think there is something vendor specific going on also with ltfs formated tapes didn't work with ltfs-hpe driver...

Getting errors in make install with the latest version:

Maybe try uninstall the old version first then build.

net-snmp is listed in makedepends, but ltfs errors with missing shared library if it's not installed, so it should probably be in depends instead.

For people having difficulty building this recently, see https://github.com/LinearTapeFileSystem/ltfs/issues/262

LinearTapeFileSystem seems to support quantum in the meanwhile. I can confirm, and please anyone with a quantum drive, please can you also confirm? See this issue on github: https://github.com/LinearTapeFileSystem/ltfs/issues/219

Here is a discussion (bug report) i started in the IBM repo. There is a lot of info inside, and we at least have product/vendor ids added now. Would be amazing if anyone could test with quantum drive. https://github.com/LinearTapeFileSystem/ltfs/issues/219#issuecomment-711160461

I have a working PKGBUILD for the IBM repo, pinned to the most recent tag. It relies on a hack that I'm not comfortable with, linking /usr/include/linux/sysctl.h to /usr/include/sys/sysctl.h.

If someone could build following these steps:

• Clone the IBM repo
• In the repo root, run ./autogen.sh followed by

./configure \
    --prefix=/usr \
    --sbindir=/usr/bin \
    --sysconfdir=/etc \
    --localstatedir=/var

• Finally, call make

I expect you to get an error about sys/sysctl.h not being found at this point.

• Make the symlink I mentioned above: sudo ln -sv /usr/include/linux/sysctl.h /usr/include/sys/sysctl.h, then call make clean and retry the steps above.

I haven't committed this workaround yet because I need to know that it works but I don't actually use this filesystem and have no way to test that it works. I find it a bit odd that there is not an already an issue logged about this error and I'm not able to find much about the error by googling except that "sys/sysctl.h" is deprecated! If someone can reproduce my error, I will log the issue upstream.

I am more that happy to continue maintenance on the package, but if there is someone out there who actually does use it and wants to take on maintenance, I will disown the package.
