22:44 <basil1x> Hello

22:45 <basil1x> Having a bit of trouble getting boincscr to work in Ubuntu 12.10

22:46 <basil1x> &whatis platform_list

22:46 <Romulus> basil1x: "platform_list" could be

22:46 <basil1x> ah.  done that already

22:47 <MTughan> What kind of trouble?

22:48 <basil1x> it says 'not installed'

22:48 <MTughan> What says "not installed"?

22:49 <basil1x> I followed the instructions on site

22:49 <PovAddict> there is no boincscr for Linux

22:49 <basil1x> boincscr in XScreenSaver

22:49 <basil1x> says there is onsite

22:49 <MTughan> What page?

22:49 <basil1x> sec... looking up link

22:50 <basil1x>  <--- under 'on Linux'

22:50 <Romulus> <> (at

22:51 <MTughan> How did you install BOINC? Through a package or the binary on BOINC's site?

22:51 <basil1x> package

22:51 <PovAddict> looks like someone pulled the description out of the unmaintained screensaver_x11.cpp and put it on the wiki

22:52 <MTughan> I notice that there's a recent edit to that effect.

22:52 <basil1x> so it doesn't really work, then?

22:52 <MTughan> By Ageless, actually. He's not nobody.

22:53 <PovAddict> anyway, Debian and Ubuntu don't build it

22:58 <basil1x> helpfully, it says there's some command line option I can use... unfortunately, it does not say how to use it.

22:58 <PovAddict> boincscr is *not* part of the ubuntu package

22:58 <MTughan> Is it even built in the binary downloadable? Or would he have to compile from source?

22:59 <basil1x> Is it possible to install it, then?

22:59 <PovAddict> I don't know what the binary downloadable has

22:59 <basil1x> oh, fun... more source code.

23:00 <basil1x> very well... if that's the only way... I knew 'free' would have drawbacks.

23:01 <MTughan> If you need the screensaver. If I remember correctly, the screensaver only shows the graphics from project applications. So check if your projects have graphics before going out and compiling from source for the screensaver.

23:01 <PovAddict> the screensaver was added in 2010

23:01 <MTughan> If they don't have graphics, the screensaver won't really do anything for you.

23:01 <PovAddict> and it wasn't touched since then

23:01 <PovAddict> I'd be surprised if it works :P

23:01 <basil1x> SETI@home has graphics

23:02 <basil1x> worked perfectly well in Win7

23:02 <basil1x> which I have since abandoned

23:05 <basil1x> so... where is this source code, please?

23:05 *** zombie67 has joined #boinc

23:06 <PovAddict> basil1x: each operating system has completely different screensaver code

23:06 <PovAddict> the Windows one does work

23:06 *** zombie67 has quit IRC

23:06 <basil1x> OK

23:07 <basil1x> how about:  where is the Linux source code, then, pls?

23:08 <basil1x> assuming it exists

23:09 <MTughan> You can, but it looks like you might have to download the latest version altogether rather than the code for a specific version. PovAddict would know more about that than I do though.

23:10 <PovAddict> well he'll have to get it from version control anyway, since boinc doesn't release source tarballs

23:10 <MTughan> Yeah, but can you get it through svn (or git, I don't know if they've switched over yet)?

23:11 <PovAddict> yeah

23:12 *** zombie67 has joined #boinc

23:12 <basil1x> will the Win7 version work under WINE?

23:13 <MTughan> Not likely, but the screensaver wouldn't in any case anyway.

23:13 <basil1x> ah

23:13 <basil1x> lovely

23:13 <PovAddict> you'd have to run the Windows version of all of BOINC including the project applications

23:13 <MTughan> But I don't think wine can hook into the screensaver anyway, right?

23:14 <PovAddict> oh he asked if it would work

23:14 <PovAddict> I think it's unlikely, but even if it does it won't act as a screensaver :P

23:14 <basil1x> right <rolls up sleeves>

23:16 <basil1x> was the linux screensaver bundled in the package I downloaded, and, if not, where can I get it, and how do I install it, and, if necessary, what will I need to compile it beforehand?

23:17 <basil1x> I realise that's a lot, but It's what I'm after, and I rarely if ever give up.

23:17 <MTughan> No, it's not included in the Ubuntu package. To get it, you'll have to download source from the subversion repository, compile it (you should just be able to compile the screensaver plus its dependencies), and then install it.

23:17 <MTughan> However, you'll have to install X development packages beforehand, which don't come with Ubuntu by default.

23:17 <MTughan> If you don't have it already too, you'll also need gcc.

23:18 <basil1x> pretty sure gcc is here from when I attempted to rebuild pidgin.

23:19 <basil1x> that didn't go so well

23:20 <MTughan> PovAddict: If the screensaver code hasn't changed in the last year or two, I guess he can just download trunk as is, right?

23:20 <PovAddict> sute

23:20 <PovAddict> sure

23:21 <basil1x> How and where can I do that, pls?

23:22 <MTughan> In a directory where you can work, run the command "svn co trunk" That'll download the source info a folder named trunk in the directory you run it.

23:22 <Romulus> Title: svn - Revision 26153: /trunk/boinc (at

23:22 <MTughan> BTW, if you hadn't figured it out, you need to run all this stuff in Terminal.

23:23 <basil1x> got that bit

23:25 <MTughan> Then before you run the next step, you'll need to install automake. "sudo apt-get install automake" should do the trick.

23:26 <MTughan> PovAddict: In configure, know which package the screensaver would be a part of? client or manager?

23:26 <PovAddict> MTughan: manager

23:27 <MTughan> Well, that simplifies things somewhat then.

23:27 <MTughan> Though I guess we always have to build libboinc.

23:28 <basil1x> OK... done all through automake install

23:28 <MTughan> svn checkout done?

23:28 <basil1x> says Checked out revision 26153

23:29 <MTughan> Good. Now cd into the trunk directory just created and run "./_autosetup"

23:30 <MTughan> Assuming that completes, you can then run "./configure --enable-pkg-manager --prefix <where you want to install it>"

23:30 <basil1x> wth is 'libtoolize'?

23:30 <PovAddict> yet another component of the autohell build system :P

23:31 <basil1x> it wants it, and apt-get says it's not there X(

23:31 <MTughan> Probably a part of libtool.

23:34 <basil1x> now wth is libcurl?

23:34 <MTughan> The library for curl, of course. :P

23:35 <PovAddict> use --disable-client

23:35 <basil1x> ??

23:35 <basil1x> where?

23:35 <MTughan> PovAddict: ./configure help says --enable-pkg-manager does that.

23:36 <MTughan> "  --enable-pkg-manager    Builds and installs components that would be present in a boinc-manager package. This is a synonym for --disable-server --disable-client --disable-libraries --enable-manager"

23:37 <basil1x> where do I put this --enable-pkg-manager statement?

23:37 <MTughan> I put it in as part of the ./configure arguments.

23:37 <PovAddict> it's an

23:37 <PovAddict> argh, system lag

23:37 <MTughan> PovAddict: That didn't look like you were lagging to me...

23:38 <MTughan> Oh, for --enable-pkg-manager... Nvm.

23:38 <PovAddict> it's an option for the configure script

23:40 <basil1x> now it wants openssl... which is already here!

23:40 <MTughan> openssl-devel

23:40 <PovAddict> ok...

23:40 <PovAddict> basil1x: did you have to install libcurl?

23:40 <MTughan> You'll encounter a couple of these as you go through. I don't know what all the dependencies are off the top of my head.

23:40 <basil1x> not here

23:40 <PovAddict> ok good

23:40 <PovAddict> install:

23:41 <basil1x> openssl-devel is not here

23:41 <basil1x> unable to locate package

23:41 <PovAddict> apt-get install libssl-dev libwxgtk2.8-dev libgtk2.0-dev

23:42 <MTughan> Oh, I'm still thinking Fedora-based distros with -devel.

23:43 <MTughan> PovAddict: Will gtk-dev or wxgtk-dev pull in Xscreensaver dev libraries?

23:43 <basil1x> this is *involved*

23:43 <MTughan> It's a one-time thing if you do this on an ongoing basis, but yes.

23:43 <basil1x> that's over 80 packages so far

23:44 <MTughan> You don't want to see how many -dev packages are installed on a developer's machine. :P You're just getting a subset.

23:44 <PovAddict> could be worse

23:44 <PovAddict>

23:44 <Romulus> Title: QDB: Quote #29888 (at

23:45 <basil1x> holy (&^$... it finished without an error at the end!!!

23:45 <MTughan> ./configure?

23:45 <MTughan> Great! Now you get to run "make" and watch for more errors. :P

23:46 <MTughan> If you're feeling a bit more adventurous, you can run "make -jn" where you replace n with the number of thread you want to run concurrently.

23:46 <MTughan> Usually the number of cores in your computer plus 1 or 2.

23:46 <PovAddict> or

23:46 <Romulus> Title: QDB: Quote #464385 (at

23:46 <basil1x> wait... it says I need something for the graphical part... way back at the beginning

23:47 <basil1x> WARNING: Development libraries and headers ("-dev") of {openGL, GLU, glut} needed!

23:47 <MTughan> That's what I was wondering about...

23:47 <PovAddict> hm

23:47 <MTughan> I don't know these package names myself unfortunately.

23:47 <PovAddict> I'm not sure if you need that

23:48 <PovAddict> any other warning?

23:48 <MTughan> PovAddict: Only needed for the libraries if you're building graphics, you think?

23:48 <basil1x> WARNING: Test for glut-dev might have failed because of missing libXmu-dev!

23:48 <PovAddict> MTughan: yes, I think that's the case

23:48 <basil1x> isn't a screensaver 'graphics'?

23:48 <PovAddict> basil1x: anything about Xcb?

23:49 <MTughan> basil1x: Yes, but you're only running graphics already built with OpenGL, not creating new ones.

23:50 <basil1x> checking for XCB... yes

23:50 <basil1x> checking for XCBATOM... no

23:50 <basil1x> WARNING: Xcb-atom not found

23:51 <PovAddict> ok, you have to install libxcb-util0-dev

23:54 <basil1x> now it says it can't find libnotify, which is here

23:54 <PovAddict> libnotify-dev?

23:54 <MTughan> Why would it need libnotify?

23:55 <MTughan> In any case, PovAddict probably has the right package.

23:55 <basil1x> Package libnotify was not found in the pkg-config search path.

23:55 <basil1x> Perhaps you should add the directory containing `libnotify.pc'

23:55 <basil1x> to the PKG_CONFIG_PATH environment variable

23:55 <basil1x> No package 'libnotify' found

23:57 <basil1x> brb... dog wants walkies rather urgently

23:57 <MTughan> Heh.
