ZFS support

Hi there,

I was curious lack of support of ZFS in LibreElec (is there any reason for that?) so i want to build my own.
Three days and still nothing.

Here is my package.md

Code

PKG_NAME="zfs" 
PKG_VERSION="2.3.0" 
PKG_SHA256="6e8787eab55f24c6b9c317f3fe9b0da9a665eb34c31df88ff368d9a92e9356a6" 
PKG_URL="https://github.com/openzfs/zfs/releases/download/zfs-$%7BPKG_VERSION%7D/zfs-$%7BPKG_VERSION%7D.tar.gz" 
PKG_DEPENDS_TARGET="toolchain linux" 
PKG_DESCRIPTION="ZFS filesystem support" 
PKG_TOOLCHAIN="autotools" 

pre_configure_target() { 
cd $PKG_BUILD 
if [ ! -f ./configure ]; then 
echo "configure script missing after autoreconf!" 
exit 1 
fi 
} 

configure_target() { 
cd $PKG_BUILD 
./configure --host=$TARGET_NAME --prefix=/usr \ 
--with-linux=$LINUX_DIR \ 
--with-linux-obj=$LINUX_DIR \ 
--disable-dependency-tracking 
# --disable-code-coverage 
} 

make_target() { 
make 
} 

makeinstall_target() { 
make install DESTDIR=$INSTALL 
} 

Which gives me error

In the zfs Makefile the line 14430 is

@CODE_COVERAGE_RULES@

I tried to disable --disable-dependency-tracking

But still it did not work as you see.

Any ideas?

Cheers,

Quote from dikov

I was curious lack of support of ZFS in LibreElec (is there any reason for that?)

We intentionally omit all forms of software RAID to reduce the scope of what we need to support and maintain. ZFS might interest a small number of people, but it's a small number. The remaining 99.9995% of our userbase has no clue what ZFS is or how to use or benefit from it's features. There's no objection to someone packaging ZFS as an add-on, but it's not for the core distro.

No ideas on the build issue .. not something I personally have time to look at right now, but others might comment.

Configure is doing strange stuff and not using the target compiler.

this will get you quite a bit further. It is not complete or fully working on the make.
