[gentoo-user] setting path for qpkg

[gentoo-user] setting path for qpkg

[James]

Hello,

qpkg is not accessible, due to the path, unless
I use: /usr/lib/gentoolkit/bin/qpkg

Where is the best (bash shell) place to
set this path once, so I do not have to
type out the fully qualified pathname
of the executable? 
I'd like it to survive the machinations of 
emerge, env-update et. al...

/root/.bashrc   ?

I also would have thought that installing it
from an emerge would set the path automatically?

I just copy it to /usr/local/bin. Since /usr/local/bin/qpkg is not owned
by gentoolkit, it won't be touched by portage. An update to gentoolkit
will reinstall qpkg in the original location, but it will be the same
version as qpkg is deprecated.

It is deprecated, which is why it is no longer in the path.

My recomendation is to create a symbolic link in /usr/local/bin (which
is in the default path)

ln -s /usr/lib/gentoolkit/bin/qpkg /usr/local/bin/qpkg

Answering your question about paths, the place to put it would
be /root/.bashrc

export PATH=$PATH:/usr/lib/gentoolkit/bin

Yes, I rather like this symlink approach.

Very kind of you to remind me via syntax on exporting the path.

Dude, (are old_farts allowed to use terms like dude?) 
with Gentoo, I do a lot of jumping. Granted, I have things
working better than ever on computers, but, I 'jump' all day
long just to keep my gentoo_boxen running smoothly. You 
do know that all computers are inherently asynchronous
(female), don't you?

It's a good thing I still play basketball with the kids,
cause Gentoo has me jumping all over the place..... Some days
I jump so much, I end up exactly where I started from. Jumping
can also be hazardous as one who has lots of electrical
devices about....

thanks for the tip.

James

That doesn't work with gentoolkit-0.2.1*, because qpkg is now
in /usr/share/doc/$PF/deprecated/qpkg/qpkg, so an upgrade of gentoolkit
would break the link.

Because it doesn't appear to offer features that qpkg does, for example;
listing all installed packages in a particular category

qpkg -I -g kde-base

Actually it does:

qlist -I kde-base

Will show all installed packages in kde-base

I just ran 'qgrep theora *' and got lots of hits,

I ran 'qgrep theoraenc *' and got nothing....

Does this mean no (ebuild) contains theoraenc ?

qpkg -i theoraenc    returns empty....too

How do I know somenthing I'm looking for (like theoraenc)
actually is or is not part of an ebuild
or a family of ebuilds like 'media-video' ?


suggestions?
 syntax using portage-utils?

"qgrep theora"  is actually similar to "grep theora $PORTDIR/*-*/*/*.ebuild"

I think what you are looking for is

#qsearch theora
media-libs/libtheora The Theora Video Compression Codec
media-video/ffmpeg2theora A simple converter to create Ogg Theora files.

also the "*" is expanded by bash to the list of the packages of the
current directory (if not surrounded writen like "*" or prefixed like
this \* )
so with grep theora * the result is to grep the ebuilds for theora and
the content of the directory you are in ;)


others will tell how to use qpkg I forgot it ;-)

So it does, neat. That will teach me to only believe the man page, it
makes no mention of this, only that it lists the contents of a package :(

There are no tools for searching for uninstalled files.  Here is what I
did

1. emerge --search theora (if you don't like the slowness, then install and use either esearch or eix)
Searching...

2. Based upon descriptions, it looks like libtheora is what I need

3. emerge -pv libtheora
These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] media-libs/libtheora-1.0_alpha3  851 kB

4. Looks okay, so run emerge -v libtheora

Hmm, nothing installed into /usr/bin, just libraries

5. Goto http://www.theora.org/ listed as the homepage

6. Click on FAQ, followed by "How can I encode videos to Theora?"

7. Get the following answer:

Have a look at ogg-theora-microhowto and transcode quicktime mov files
to Theora files under Linux. You can use libogg, to wrap theora video
with vorbis audio in Ogg file.

A user-friendly way to convert .dv and .avi format video into Ogg Theora
format is with ffmpeg2theora. It can be found at:
http://www.v2v.cc/~j/ffmpeg2theora/

A way to both stream and encode theora format video is with videolan
(VLC). 
Example for streaming the video4linux device in ogg theora/vorbis: 

vlc v4l:/dev/video:input=3:norm=pal:size=384x288 --sout \ 
'#transcode{vcodec=theora,vb=300,acodec=vorb,ab=96}:std{access=http,mux=ogg,url=server.example.org:8000}'

Or, replace "v4l:/dev/video:input=3:norm=pal:size=384x288" with a
filename if you want to transcode.

For more on the vlc syntax, see: 
http://videolan.org/doc/videolan-howto/en/ch09.html

9. So in order to encode theora files, I need to install ffmpeg2theora
and/or vlc.  I saw ffmpeg2theora listed in the previous emerge --search,
but it was masked.  Let's look at vlc

10. emerge --search vlc
Searching...
[ Results for search key : vlc ]

      Homepage:    http://www.videolan.org/vlc/
      Description: VLC media player - Video player and streamer

11. emerge -pv vlc
These are the packages that I would merge, in order:

12. It's not masked and has a theora USE flag.  So I'm presuming that adding "media-video/vlc theora" to /etc/portage/package.use and running emerge -v vlc will do it

Paul

Also, qlist kde-base/arts-3.5.0 is *much* faster than 
qpkg -l kde-base/arts-3.5.0
