CDEPEND is a commonly used name for COMMON_DEPEND - dependencies shared between
DEPEND and RDEPEND (and, potentially, PDEPEND). In cases where you have a fair
number of shared dependencies, and one or two in only DEPEND or RDEPEND, you
could enter the common ones in a variable (commonly CDEPEND) and add that to
your {,R}DEPEND definition.

Use of CDEPEND is common, but not policy. You can find other examples of it's
usage with `qgrep -H CDEPEND` (qgrep is provided by app-portage/portage-utils).

You could always use a Google search of "CDEPEND site:devmanual.gentoo.org" (or
similar), but otherwise there isn't that I'm aware of.

There is, however, a definition of CDEPEND in the Java Developer Guide[0] on the
wiki (as found with Googling "CDEPEND site:wiki.gentoo.org"). Note that the wiki
*does* have native built-in searching, though).

and I see CDEPEND::

 CDEPEND="dev-java/ant-core:0"

Compile-Depend? If so, what's the difference in DEPEND and CDEPEND?

Googling only produced examples with CDEPND, no clear definition::

[2] https://devmanual.gentoo.org/eclass-reference/autotools-utils.eclass/

Do you have a definition of exactly what a CDEPEND is?

Those (2) aforemention docs do not show CDEPEND in the local search, as 
they (occurences of "CDEPEND") are found in non-text parts of the documents.


Is there way to globally search doc indexs like: [3] ?

Huh. OK. Never looked at this closely before. It strangely makes sense
but, I'm going to have to marinate on this..

Beats me too. That why I'm going to marinate on this. Perhaps if somebody
was to shed a bit more light on the circular need, it might ease the
effort of understanding.

Thanks for the the insight.

Unless you have a NVMe motherboard and disk (which are quite new and you
would likely know about it), leave it off as it wont/cant be used.

Most SSDs are AHCI, so make sure the kernel is configured for that and
controller is using that in the MB settings, otherwise you will be use an
older, slower interface.

Before you curse give rtmpdump a spin, because it may be able to capture the 
stream and save, or pipe to vlc/mpv with rtmpsrv, or rtmpsuck.

It's intentional. In jflex-1.6.1.ebuild, you'll find...

  PDEPEND=">=dev-java/javacup-0.11b_p20151001:0"

That's a "post-merge" dependency, and they exist to get around

[gentoo-user] new packages has no dependencies

[James]

Hello,

After a sync, One of the new packages called for install was
dev-java/jflex

equery depends came back empty
and it's not in the world file.

strangely, why is my system asking for this package to be installed?

It is related to maven-bin but that's not showing up on the dep. tree.
I do have dev-java/maven-bin installed.

jflex does not show up in maven-bin-3.3.3-r1.ebuild

I guess I need enlightenment? a bug?


So now I installed it anyway, and guess what, a dependency now shows up::
dev-java/javacup

and 'equery depends javacup'  yeilds::
dev-java/jflex-1.6.1

A circular! yippie. So how do I post this bug? Can somebody confirm it?
just weird.

Indeed. I use cvlc, which displays just the stream in a window without
all the clutter of menu and navigation controls, to display feeds from
security cameras like this. You can also pass it more than one URL and
use the N and P keys to move between the streams.

Hi Alan,

I feared that...I had a somehow screwed up idea of something and
due to that it looks like highly complex too meand the solution
are programs I use to use nearly every day!
Thanks for the slight slap onto the back of my head ;) :))

Yep. If you can't do it with either vlc or mplayer, then it's likely
going to require some actual writing of code to impliment somebody's
halfwitted home-made streaming protocol.

When you get to the web page and get it playing, look at the page
source for hints as to the actual streaming protocol and URL for the
stream.  If you're lucky, somewhere amongs the HTML, there's a URL
that you can hand to vlc or mplayer, and it will "just work".

If that doesn't work, you can use wireshark to try to spot the
streaming connection getting started up when you click "play".

If it's flash, I don't know what you do other than curse at Adobe and
the web page developer...

[gentoo-user] Webcamviewer (or such) ?

[Meino . Cramer]

Hi,

For watching different wildlife webcams of the internet for a longer
period of time I am looking for something, which I tend to call
"webcam viewer"...(Warning! Not-native-english-speaker ahead! ;)

Normally one opens up firefox (or any other browser), enter the
URL and get the interface of the webcam displayed...sometimer with
more than one port to watch. The resolution of these streams are
low most of the time...nonetheless I need a completey firefox and
its memory footprint is not that of a child.
Rendering a complex scene with blender in parallel let my PC with
8GB start swapping from time to time.

I am looking for something, which displays one port/one stream of
such an URL in a window sized according to the physical resolution
of the stream, so I can pin it in one corne of my display without
interfering with the rest and without killing my RAM.

Or is this complete idea nonsense ? ;)

What is the recommended application for such a task?

Thank yo very much in advance for any help!

Best regards,
Meino

[gentoo-user] Open-Channel SSD target support option

[Jacques Montier]

Hello all,

In the new stable kernel configuration (4.4.6-gentoo-sources) there is the
option :

*Open-Channel SSD target support (NVM) [N/y/?] (NEW) ?*

*CONFIG_NVM:*

*Say Y here to get to enable Open-channel SSDs.*

*Open-Channel SSDs implement a set of extension to SSDs, that*
*exposes direct access to the underlying non-volatile memory.*

*If you say N, all options in this submenu will be skipped and disabled*
*only do this if you know what you are doing.*

*Symbol: NVM [=n]*
*Type  : boolean*
*Prompt: Open-Channel SSD target support*
*  Location:*
*-> Device Drivers*
*  Defined at drivers/lightnvm/Kconfig:5*
*  Depends on: BLOCK [=y]*


Gentoo is installed on a 256 Mo Crucial SSD and  i see the line "*only do
this if you know what you are doing"...*
So is it safe to select this option or not ?

Thank you in advance for your response,

Regards,
