Newer versions of mount(8) will use /proc/self/mountinfo if it detects that the final target of /etc/mtab (possibly /proc/self/mounts) is not writable. - -- Jonathan Callen -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCgAGBQJTVzHvAAoJELHSF2kinlg41ssP/1JO8FTHrGt6NPZm39BvMOrm GEAcQ5ZlHuzVjNc9lImYHrsiWpVXfikTqecR1P9sXZa98eZfrqXhlzpe+vZQxLu0 x/zki3wA29htlfvpRV+Bi8yieWVenNBhWkRq09nzLgglQWBsRFJUU+kIAtDX5Ynf E2MmZsa6K7uhy1Lrg4LVyqEjb1671fVvphQiB1zvjIjWc08tEqB/v4BMPuODbtJS Ame4AgvA89EFr0K1kw0NAOtxgmcpVjof1onwda8g6V84tIaq98279ratmM+knJFg 586+YKF9Ffd41twtYF3ANYgy9ruFLSZ/jlnV78IbH3FqPvzxqWmfNvET030Oq0q0 A67t4fwYO62PEwCcOlSnVLLfAQhFPKTv+Yqj1hI8l/64o52CHXIQzhnADJouw8aL i4OBkYAaFDv/uQsydsa3hQ519OG058nQZ/Sr+AN1qyp6Axum9GFqOvIzMEHpEH4P tb8Prvp+drNU+AC8uIEvCsaSSUC4wLpywwV23iAzrOQdG14SAkkz8Znrty1tSHc1 Y4lmiS4U9xRMGx1Mvz8Xat3yBOl/bRS0mAejKqjSDdZ+6Rtq1gZ7LhdBeG5Nokla Kdx1JO+QvcQDDnIj64qq6Hq1MY3zu+WYRiacx7KvpsuyIDM+Pc6qCJaRYGYveWW9 aDWZ2siL8DaOwYeRT48L =jgV4 -END PGP SIGNATURE-

(No, I can't explain why, I just do ;) For that reason I'd suggest running fix_libtool_files.sh, just in case your gcc ebuild didn't do it automatically. FWIW, opensp builds successfully for me and my configure logs look very much like yours (I'm using gcc-4.8.2/~amd64, though.)
Re: [gentoo-user] Point
The final -option gives me a dot instead of a comma on the keypad. Thank you for your answer, but I have just got the solution: In /etc/X11/xorg.conf.d/10-evdev.conf I have: Section "InputClass" Identifier "keyboard" Driver "evdev" Option "XkbLayout" "fr" Option "XkbModel" "pc105" Option "XkbOptions" "compose:lwin,kpdl:dot" MatchIsKeyboard "on" kpdl:dot was the key to solve my problem Regards Roger

Problem is not in this environment variable(which influence on few packages like webkit-gtk, libreoffice) but in OpenSP package which has no common with it.

Can you copy either of them into /etc/mtab and have the > correct result? I duped a Gentoo VM on my laptop, launched it, and looked at the output of "grep ' / ' /proc/mounts" in the "/mnt" chroot after mounting "/mnt/proc" before and after the chroot, which is unsurprisingly the same. What are you trying to find out? I haven't used lilo for 12 years at least. Does it operate using "/proc/self/mounts" or "/etc/mtab"? mount/umount, for example, use "/etc/mtab". grub-install, AFAIR, uses "/proc/self/mountinfo" as well as the "/sys/devices/" hierarchy. localhost ~ # mount /dev/vdb1 /mnt localhost ~ # mount -t proc proc /mnt/proc localhost ~ # chroot /mnt localhost / # grep ' / ' /proc/mounts rootfs / rootfs rw 0 0 /dev/disk/by-uuid/fe087ffc-ccb6-48ce-a8f7-a3a6d0fb20e3 / xfs rw,relatime,attr2,inode64,noquota 0 0 /dev/vdb1 / xfs rw,relatime,attr2,inode64,noquota 0 0 localhost / # exit exit localhost ~ # umount /mnt/proc localhost ~ # chroot /mnt localhost / # mount -t proc proc /proc localhost / # grep ' / ' /proc/mounts rootfs / rootfs rw 0 0 /dev/disk/by-uuid/fe087ffc-ccb6-48ce-a8f7-a3a6d0fb20e3 / xfs rw,relatime,attr2,inode64,noquota 0 0 /dev/vdb1 / xfs rw,relatime,attr2,inode64,noquota 0 0 localhost / # exit exit localhost ~ # xfs_admin -u /dev/vda1 UUID = fe087ffc-ccb6-48ce-a8f7-a3a6d0fb20e3 localhost ~ #

I did check anyway to be sure. -- Regards Peter
