Bug 259341 – sys-fs/btrfs-0.16-r2 + gentoo-sources-2.6.28-r2 - volumes.c:86: error: implicit declaration of function 'close_bdev_excl'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Helmut Jarausch 2009-02-17 10:25:55 UTC]

trying to emerge sys-fs/btrfs-0.16-r2 (with a gentoo-sources  2.6.28-r2 kernel)
fails on an AMD64 system (it builds just fine on a similar but x86 system)
with:

volumes.c: In function 'btrfs_cleanup_fs_uuids':
volumes.c:86: error: implicit declaration of function 'close_bdev_excl'
volumes.c: In function 'btrfs_open_devices':
volumes.c:370: error: implicit declaration of function 'open_bdev_excl'

and  - maybe harmfull on an AMD64 system -
volumes.c:370: warning: assignment makes pointer from integer without a cast


Reproducible: Always

AFAIK btrfs support was added in 2.6.28 so you should either use this package with <2.6.28 or use >=2.6.28 properly configured.

[Comment 2 Joe Peterson (RETIRED) 2009-02-24 05:15:15 UTC]

Correct.  The live ebuild should technically work with later kernels, but still, better to use the in-kernel version.  I should probably put a kernel restriction in the ebuild for 0.16...

[Comment 3 Joe Peterson (RETIRED) 2009-02-24 05:41:13 UTC]

Added the restriction to the 0.16 ebuild.
