Building ZFS from sources : missing depmpfs sources
captain-haddock17 opened this issue · comments
Dear ZFS developers !
Id like to compile ZFS from sources, by following instructions in
Installing from sourc.
Launching ./zfsadmin.sh for configuration and compilation, I got somme errors on:
bin/sh ../../../libtool --tag=CC --silent --mode=link clang -Wall -Wshadow -Wstrict-prototypes -fno-strict-aliasing -g -Os -Wno-tautological-constant-out-of-range-compare -lstdc++ -o kextsymboltool kextsymboltool.o ./kextsymboltool -arch x86_64 -import allsymbols -export zfs.exports -output KernelExports_64
exported name not in import list: _decmpfs_cnode_alloc
exported name not in import list: _decmpfs_cnode_free
make[4]: *** [KernelExports] Error 1
Old OsX? If so, delete them from spl/module/spkl/KernelExports/zfs.exports
I found out that decmpfs source code is part of Apple's Opensource kernel.
57209 31 jan 19:13 ./xnu-4903.270.47/bsd/kern/decmpfs.c
8123 31 jan 19:13 ./xnu-4903.270.47/bsd/sys/decmpfs.h
I'm not quite comfortable with autogen and automate& al.
so as to declare these kernel source code.
Sorry,
William
Hmm did they change something.. check
# grep decmpfs spl/module/spl/KernelExports/allsymbols
$ grep decmpfs -n spl/module/spl/KernelExports/allsymbols

So they did, updating my mojave now and let's see if I get the same issue
Hmm no it appears normal, did you update xcode and it's component ? decmpfs_cnode_alloc doesn't exist in 10.13 and earlier, but still in latest Catalina

As I understand,
_decmpfs_cnode_alloc
_decmpfs_cnode_free
are already present on my system.
but not found at link time.
Good, it's in there. Something else must be going on with the build.
Yes, zfs.exports ask for them, the we produce all symbols in to allsymbols, then when spl links, it links against them. ZFS will complain they dont exist, but carry on.
Hi Jörgen,
I can't carry on with this for now.
Could you please give me a corrected build script ?
Thanks a lot,
William
Can you start again with sources? I have re-compiled everything on Mojave to make sure it works. You have shown that your kernel does have the decmpfs_cnode_alloc function.
