Getting rid of gcc-4.7.3...how?

Hi,

(this happens on a embedded system)

I ran into a problem I think...

As adviced I run 

    emerge --depclean -v -p

after a greater update to world.
(by the way: Updateing the world is generally to a bad idea...;)

Beside other things, gcc-4.7.3 was slated for removal. As 
gcc-4.8.3 was already installed and gcc-config shows that it
is active, I started the above command without "-p"....
And it screws up the whole thing badly:
There were many, many applications (the shell for example...)
which were directly linked to
/usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libgcc_s.so.1
and/or
/usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libstdc++.so.6

After clearing the sdcard and reinstalling the backup I started
to emerge all affected ebuilds by hand...only to find, that they
were again linked against the old libs.

I checked again with gcc-config and found:

beagleboneblack:/root>gcc-config -L

virtual/emacs-24

After reading a few google hits of gentoo documetation about virtual
pkgs.  I still didn't get it.

In my case I'm trying to avoid problems with a self built emacs (25)
not done thru portage.

I'm not looking to discuss the pros and cons of doing in this thead,
but want to understand how it will effect things in the situation
described below.

I also want to install emacs-w3m (thru portage)

emacs-w3m requires:

  [ebuild  N     ] app-admin/eselect-emacs-1.17  0 KiB
  [ebuild  N     ] app-emacs/emacs-common-gentoo-1.4-r1  [...]
  [ebuild  N     ] app-editors/emacs-24.4-r1:24  [..]
  [ebuild  N     ] virtual/emacs-24  0 KiB

  [...] a few other pkgs

I didn't want to have the confusion of another version of emacs
installed so resorted to use of:

/etc/portage/profile/package.provided: like so:
      app-editors/emacs-24

 To tell portage about my home rolled emacs

Well, that knocks down most of the unwanted pkgs but still as you see:

Identifying a file by a block number...how?

Hi,

with

    sysctl vm.block_dump=1

one can enable the logging of IO to the harddisk/flashmem/...
into dmesg.
The logs report the block number of the file in question...
but not the filename itsself.

Is there any other way as examine each single file of the
filesystem to find the file to which a certain block number
is assigned?

Thank you  very mcuh for any help!
Best regards,
Meino

No burners are currently available

When I start Xfburn I get a message:
No burners are currently available
Possibly the disc(s) are in use, and cannot get accessed.

How to check which program is using the DVD drive?
"ps fax" is not showing that any program is using it.

sysctl not executed at boot time

Hi,

It seems that my sysctl.conf is not executed at boot time. If a apply a
sysctl -p after boot, it adjusts a lot of parameters I added to syscl.conf.

A rc-update shows the the sysctl server should start a boot time.

Any ideas?

Mit freundlichen Grüßen,

Michael Schwartzkopff

BluRay reproduction

Hello!

Someone had already played BD Video discs

I bought a Pioneer BD player/recorder and I want to play BD films on it, but the things I found in net were (a) badly documented, (b) confusing and/or (c) Ubuntu oriented.

Any tips? Already tried to put bluray on USE flags  and all the things I could and nothing... :(

Garbled manpages OR terminal corruption OR ...

Hi,

Currently I haven noticed a few manpages (for example 'man ftop'),
which miss kinda second part of a sentence.

For ftop:

FTOP(1)                     General Commands Manual                    FTOP(1)

NAME
       ftop - show progress of open files and file systems

SYNOPSIS
       ftop [options]

COPYRIGHT
       ftop  is  Copyright  (C) 2009 Jason Todd.  Send bug reports and sugges‐
       tions/patches/etc. to jtodd1 <at> earthlink.net.

                Show all files that are open within the  displayed  processes.

ftop 1.0                          2009-02-16                           FTOP(1)

See the end of the explanation for option '-F'.

As it happens on all three embedded systems and my Linux PC it cannot
be something architecture dependant.

All systems are setup 'the same way' - regarding the applications
related to this effect (and hopefully I havent overlooked something.

It would help, if someone else could check this at her/his system...

What may ve the reason for this?

Thank you very much in advance for any help!

Best regards,
Meino

PS: If I came across more of the cutted sent
    I will post another email to this mailin
    ;)

How to install a pkg without all dependencies?

Setup: very new install of gentoo

I want to install emacs-w3m without most of the dependencies:

Calculating dependencies... done!

I don't want to install another (older) version of emacs.

I installed emacs outside portage from bzr sources.  I'd sooner track
emacs development my way.

I vaguely remember some way to tell portage about that... but not
enough to do it...

What is the correct way to remove an old gcc-version (emerge --depclean) ?

Hi,

on my embedded system I currently ran into a problem:

As adviced after a greater world update I did 

    emerge --depclean -vp

beside other stuff sys-devel/gcc was shown as candidate
for removal. An old version was shown for removal and
a newer one was shown as preserved.

I checked with eselect, whether the new version was selected
(it was), made a backup and started emerge --depclean -v.

As soon it has removed gcc, a firework of error brightened
my terminal...beside other things the shell failed while
trying to access libgcc (if I had recognized that correctly...).

Technically no problem: I stopped that, cleared the sdcard
and installed the backup...but what did I wrong here?

What is the correct way to handle such things?

Best regards,
Meino
