[gentoo-user] ZFS on Linux (spl build error)

[Michael Rühmann]

Hi all,

had some troubles to build sys-kernel/spl-0.6.2-r2.

<snip>
 >>> Emerging (4 of 6) sys-kernel/spl-0.6.2-r2

Thanks in advance for any help,

You could at least say how you did it. *sigh*

maybe even add the kernel part to https://wiki.gentoo.org/wiki/ZFS

well, you won't find it in menuconfig. Or at least I couldn't. You can
reach that option in xconfig.

On the other hand ZLIB_DEFLATE is turned on by a douzend of other
options that it is VERY probable you never have to touch it.

Nothing, but you've not answered the question. you have only shown that
you do have the option set, not how you set it.

exactly.. i couldn't find it in menuconfig.
The answer was to set CONFIG_CRYPTO_DEFLATE=y manually in .config.
After building the new kernel, CONFIG_ZLIB_DEFLATE was pulled in and spl 
compiled without any problem.

There is nothing difficult about that :-)

xconfig doesn't turn on options that aren't there in menuconfig ... you just
might be able to navigate xconfig's interface better.

Any time you can't see how to enable a kernel option, just search for it and
look at the Selected By field to see what you need to turn it on:

Symbol: ZLIB_DEFLATE [=y]
Type  : tristate
  Defined at lib/Kconfig:198
  Selected by: PPP_DEFLATE [=n] && NETDEVICES [=y] && PPP [=n] || BTRFS_FS [=n] && BLOCK [=y] || JFFS2_ZLIB [=n] && MISC_FILESYSTEMS [=y] && JFFS2_FS [=n] || LOGFS [=n] && MISC_FILESYSTEMS [=y] && (MTD [=n] || BLOCK [=y]

My personal preference is nconfig ... easy to navigate, nice colors on black bgd.

YDIW ... it's never a good idea to edit .config by hand. Always use one of the
"make <some>config" commands.

I saw the option in xconfig. I did not see it in menuconfig.

xconfig has a setting to show options that are only enabled by other
options.

Show normal options: ZLIB_DEFLATE is hidden
Show all options: ZLIB_DEFLATE is visible and can be changed.

and you are missing half of it:
Selected by: PPP_DEFLATE [=n] && NETDEVICES [=y] && PPP [=n] || BTRFS_FS
[=n] && BLOCK [=y] || JFFS2_ZLIB [=n] && MISC_FILESYSTEMS [=y] &&

BLOCK [=y]) || CRYPTO_DEFLATE [=y] && CRYPTO [=y] || CRYPTO_ZLIB [=m] &&
CRYPTO [=y]

oh look: crypto_zlib turns it on too.

> My personal preference is nconfig ... easy to navigate, nice colors on black bgd.

but it seems that nconfig is hiding information from you, that xconfig
delivers.

There's always a lot to learn :D
I will have a look at nconfig and give it a try in the future.

Many thanks for the tips, Bruce

As per another post, but my mouse paste came up short. Let me try again:

Selected by: PPP_DEFLATE [=n] && NETDEVICES [=y] && PPP [=n] || BTRFS_FS [=n] && BLOCK [=y] || JFFS2_ZLIB [=n] && MISC_FILESYSTEMS [=y] && JFFS2_FS [=n] || LOGFS [=n] && MISC_FILESYSTEMS [=y] && (MTD [=n] || BLOCK [=y] ) || PSTORE [=n] && MISC_FILESYSTEMS [=y] || CRYPTO_DEFLATE [=y] && CRYPTO [=y] || CRYPTO_ZLIB [=y] && CRYPTO [=y]

Which combination depends upon your use case.

No, it was 100% user error. Trying to do 14 things at once, and no matter what
any human says, when we "multi-task" we don't do *any* of the >1 tasks as well
as we do "exec task1 ; exec task2 ; exec task3 ; done"

Here's what I should have pasted:
