[gentoo-user] lvm2 emerge problem

[gentoo-user] lvm2 emerge problem

[Leopold Gouverneur]

emerge lvm2 abort during compilation with this message:
...
../include/lvm-string.h:40: attention : 'struct dm_pool' declared inside
parameter list
...

wordir/.../lvm-string.h i see:
...
struct pool;
       ^^^^
....
char *build_dm_name(struct dm_pool *mem, ....
                           ^^^^^^^
.....

It is not surprising then that the compiler complains about
dm_pool being declared inside parameter list!
Now what surprised me, was that if i untar  LVM2.2.02.05.tgz
and look in lvm-string.h, i see:

...
struct dm_pool;
       ^^^^^^^
...
char *build_dm_name(struct dm_pool *mem, ....
...
which makes the compiler happy.

How and why was this file changed?

I don't see any change in this file:

What use flags are you using?  Because somehow I managed to merge
2.02.05 without hitting this problem.

[ebuild  N    ] sys-fs/lvm2-2.02.05  USE="nolvm1 nolvmstatic nosnapshots
readline -clvm -cman -gulm -nomirrors"

Anyway i think that without a previous declaration of dm_pool the
compilation should abort.But since i seem to be the only one
encountering that error the problem is surely with me but where???

Well it is definitely a bug in the code...the declaration *should* be
dm_pool.  But for some reason I don't get a fatal error from this.
Even using the same USE flags, I don't seem to have an issue with
this...

Maybe it is CFLAGS or gcc version?  I am using:

[gentoo-user] Probems with radeon and drm after using kernel-2.6.16-gentoo-r7

[JC Denton]

[-- Attachment #1: Type: text/plain, Size: 2652 bytes --]

Hello!
 
 I am building a kernel-2.6.16-gentoo-r7 but I have a problem. First I tried to use greempt for the cpu. Because this does not work I build the kernel without again. But I still get :
 
 drm: version magic '2.6.16-gentoo-r7 PENTIUMM gcc-3.4' should be '2.6.16-gentoo-r7 preempt PENTIUMM gcc-3.4'
 [drm] Initialized drm 1.0.1 20051102
 radeon: version magic '2.6.16-gentoo-r7 PENTIUMM gcc-3.4' should be '2.6.16-gentoo-r7 preempt PENTIUMM gcc-3.4'
 
 I am now using the preempt latency option that I was using under 2.6.14 without problems.

Your out-of-tree modules are still compiled against your old config.  To 
fix this:

1) Correct your /usr/src/linux symlink, if needed, so that it points to the 
source tree of your running kernel.
2) Make sure the /usr/src/linux/.config file matches your running config.  
If you have no qualms about trampling the existing file this is easy 
enough to do with 'zcat /proc/config.gz > /usr/src/linux/.config'.
3) emerge module-rebuild
4) module-rebuild -X rebuild

That should make sure the modules installed are appropriate for your 
running kernel.

It could also be that your in-tree modules got compiled, but never 
installed over the old versions.  If that's the case, follow steps 1 and 2 
above, but then:
3) cd /usr/src/linux; make modules_install

That will compile the modules against the current config (if necessary) and 
install them under /lib/modules/$(uname -r) where modprobe expects them to 
be.

emerge --info
Portage 2.1_rc1-r2 (default-linux/x86/2005.1, gcc-3.4.6, glibc-2.4-r3,
2.6.17-rc4-mm1 i686)                          ^^^^^^^^^ 
=================================================================

when i compile lvm2 myself it succeed as root but fails as ordinary
user, because as user i use gcc-4.0.2 that i dowloaded and installed
under /usr/local.
I thought that was safe because emerge run as root and /usr/local/bin is
not in root PATH.But although emerge --info says  gcc-3.4.6, it seems to
use 4.0.2.Now why this fails is perhaps related to the presence in the
4.0.2 tree of a libdevmapper.h file quite different from
/usr/include/libdevmapper.h.
Anyway, the lesson for me is: Be carefull before installing things
outside emerge control!

Thanks for your help.

[gentoo-user] what to do to remove all kde dependencies and kdelibs

[JC Denton]

[-- Attachment #1: Type: text/plain, Size: 510 bytes --]

Hi!
 
 What can I do to remove all kde dependencies from my system? In have "-kde" in my /etc/make.conf and already did a emerge --depclean and revdep-rebuild after I did an emerge --update --deep --newuse world. But there is still a lot of kde stuff on the system. how can I check if an application still uses this stuff? How to remove the stuff savely?
 
 Thanks!

Many applications require kdelibs, the kde use flag merely determines whether 
certain packages will have optional kde support.

Also, start a new message when posting to the mailing list, rather than 
replying to an existing message.

Put -qt and -arts in USE too.

'equery depends kdelibs' will show you.

Also, do 'grep kde /var/lib/portage/world' to see whether you have
inadvertently added a KDE package to your world.

~# emerge --info
Portage 2.1_rc1-r2 (default-linux/x86/2005.1, gcc-3.4.6, glibc-2.4-r3,
2.6.17-rc4-mm1 i686) 

There is my problem.I installed gcc-4-02 whithout emerge thinking that
under /usr/local it was in a safe place (not in root PATH).
Now when i untar and compile  LVM2.2.02.05.tgz as root it uses gcc-3.4.6
and everything is OK but as user it uses gcc-4.0.2 and it fails!
Although emerge --info says gcc-3.4.6 , it fails because it uses
gcc-4.0.2 ( the error messages are exactly the same ).
Now, why it says one thing and does another and why 4.0.2 fails where
3.4.6 succeeds is another question.I noticed the presence of a file
libdevmapper.h under /usr/local/lib/gcc that was quite different from
/usr/include/libdevmapper.h. I replacing it with a symlink and the
emerge succeeded. But is that safe? Anyway,for me the lesson is clear:be
carefull before installing something outside portage control!

Thankx!
