Bug 281673 – <sys-block/iscsitarget-1.4.19: kernel modules build fails in some cases

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Vitaly V. Bursov 2009-08-16 13:14:53 UTC]

If the current running kernel version differs from what sys-block/iscsitarget is built against build fails.

Reproducible: Always

Steps to Reproduce:
# running kernel version is different from /usr/src/linux (or $KERNEL_DIR)
$ uname -r
2.6.18-028stab062-2
$ stat /usr/src/linux
  File: `/usr/src/linux' -> `linux-2.6.18-openvz-028.064.4'

# emerge sys-block/iscsitarget

Actual Results:  
build fails with:

Fixed with:

+        emake KSRC="${KERNEL_DIR}" usr || die "failed to build userspace"
