Gentoo how to compile LVM statically linked?

Question

A Gentoo install still in the livecd stage (unable to boot so far) fails to emerge LVM statically. I need a statically compiled lvm in order to use it in my initrd.

My make.conf:

CFLAGS="-O2 -march=native -pipe"
CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"
USE="bindist mmx sse sse2 static"

The emerge compile error:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/../../../../lib64/libudev.a(time-util.o): In function `now': (.text.now+0x8): undefined reference to `clock_gettime'

I also note that:

• Warning, we no longer overwrite /sbin/lvm and /sbin/dmsetup with
• their static versions. If you need the static binaries,
• you must append .static to the filename!

What does this mean? How am I supposed to append this ".static" to the filename?

I see that this person had the same issue, but with no answer: http://archives.gentoo.org/gentoo-user/msg_eb40f5d76161fda72d134551cc26d989.xml

I also notice this thread: http://forums.gentoo.org/viewtopic-p-4892618.html?sid=e41b07d9b8554c10430619e1f51d564a

I tried export LDFLAGS=" -lrt "

However it didn't appear to change anything, still the same error.

Works fine for me (in ~amd64 Gentoo), however try removing the udev useflag from lvm2 as a workaround, as udev is not important at initramfs stage. The static binary is called /sbin/lvm.static (requires static useflag to be built). You can check whether a binary is static or not using ldd.

echo sys-fs/lvm2 static -udev >> /etc/portage/package.use

Also check whether you have the static-libs useflag enabled, for the dependencies of the packages you wish to be built statically. Usually the ebuilds should check those dependencies for you, but better to double check.
