 |
|
Hi there
I'm currently in the process of installing Gentoo on second box. The root fs will reside
in a lvm logical volume on top of a luks-encrypted device. I prefer to create my own initramfs
and consequently I need static binaries of lvm2 and cryptsetup. However
| Quote: |
livecd src # equery uses lvm2
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for sys-fs/lvm2-2.02.97-r1:
U I
+ + lvm1 : Allow users to build lvm2 with lvm1 support
+ + readline : Enables support for libreadline, a GNU line-editing library that almost everyone wants
+ - static : !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
+ + static-libs : Build static libraries
+ + thin : Support for thin volumes
+ + udev : Enable sys-fs/udev integration (device discovery, power and storage device support, etc)
|
Indeed, emerging lvm2 with static USE flag enabled doesn't work at all. Here's the build log:

Right now I'm puzzled. How am I supposed to create to finish bootstrapping/installation, if I won't be able to boot
my new system. Can anyone give me a little hint on how to obtain a static lvm2 binary in this situation? |

The use flag actually does work, although you may need to add static-libs. You can use ldd to confirm. A dynamic build will link to libraries. A static one will link to numbers. I would recommend you also use busybox. It makes the initramfs so much easier.
I don't know what is causing your build failure, but I suspect it is related to udev. You may be able to disable this use flag as a work around or update udev.

Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box. |

Thanks for the input. You were indeed right. I changed USE flags to
| Code: |
Found these USE flags for sys-fs/lvm2-2.02.97-r1:

+ + lvm1 : Allow users to build lvm2 with lvm1 support
+ + readline : Enables support for libreadline, a GNU line-editing library that almost everyone wants

and I was able to build lvm2. The relevant part of the build log seems to be
| Code: |
/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 found this post on in the Mailing List archives
http://archives.gentoo.org/gentoo-user/msg_eb40f5d76161fda72d134551cc26d989.xml
that seems to address a similar issue. Following the advice there I investigated /usr/lib64/librt.a
| Code: |
livecd initramfs # readelf -s /usr/lib64/librt.a | grep clock
File: /usr/lib64/librt.a(get_clockfreq.o)
9: 0000000000000000 362 FUNC GLOBAL DEFAULT 1 __get_clockfreq
File: /usr/lib64/librt.a(clock_getcpuclockid.o)
7: 0000000000000000 207 FUNC GLOBAL DEFAULT 1 clock_getcpuclockid
File: /usr/lib64/librt.a(clock_getres.o)
9: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND __get_clockfreq
10: 0000000000000060 403 FUNC GLOBAL DEFAULT 1 clock_getres

14: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND __get_clockfreq
File: /usr/lib64/librt.a(clock_nanosleep.o)
7: 0000000000000000 144 FUNC GLOBAL DEFAULT 1 clock_nanosleep

I don't have any experience with these library issues and therefore I can not really interpret this output but it seems that `clock_gettime' is
defined. Well, maybe someone can shed some light on this issue. In the meantime I will try to proceed with lvm2 without udev support.
Thanks again for your help, very much appreciated  |
