Howto: Install and use projectM music visualizer with pulseaudio support on Hardy

[struktured]

In regards to "alsa input" support,

there is alsa-based line in and mic support available via the project-libvisual-alsa subdirectory (turn on INCLUDE-PROJECTM-LIBVISUAL-ALSA and rebuild to test it out).

It would be nice if you could also make some more or less official ubuntu packages for the 1.2 version... then nobody would have to wait for much too long times until the MOTUs do something

[struktured]

Well the projectM developers (Pete and I) don't actually use ubuntu- so rather than wasting time not developing, we prefer that an ubuntu guru who likes projectM puts in the effort to do it (with our help if necessary). Also, we are terrible at making releases to begin with!

No problem with that, I just asked .

Anyway: Could you implement an optional internal FTGL like you did for GLEW, at least if it's not too much work? FTGL hasn't released something new since 2004 (seems dead to me), it is statically linked anyway, and it hasn't got a that huge codebase, so it shouldn't be much of a problem. An internal and thus known-to-work FTGL would help much, especially because all FTGL versions in ubuntu since edgy lead to segfaults (both the edgy/feisty/gutsy/hardy "-3"s and intrepid's "-4"), at least since version 1.1 (It worked in ubuntu's 1.01). I suppose keeping it optional would still be the better way to go . I don't know how much work it is, but I think you should at least consider that.

And please make ProjectM compatible to Qt4.4 before 1.2, I would like to stop holding back the update to Qt4.4 .

And for the last, a bigger feature request that came over me while writing this post - I will gladly post it at sourceforge if you wish, but as we discuss here anyway, I'll better port it here: If it isn't already planned, add (optional) DBus support to the Qt backend (fits there most because it is only needed for standalone apps anyway and because Qt4 has DBus bindings - article: http://doc.trolltech.com/qq/qq20-dbus.html). This would allow scripting in Amarok and a multitude of other things because it could allow for example track name display in the standalones.

If you don't want me to make these requests here, I wouldn't have a problem to post it to the sourceforge wishlist, but as we discuss here anyway, I think asking here is better, 2 of 3 problems are helping this thread anyway . For an official package in intrepid, I really think that the first two problems have to be resolved first, as intrepid will certainly contain qt4.4 and doesn't up to now contain a working ftgl-dev.

Excuse me for the much too long post .

One feature request that I posted at the bug tracker that should be pretty trivial to implement (I think) would be a sync to vblank on/off switch in the projectm preferences pane. Would save users having to force it on in their respective card control panels, and it certainly does make projectm look MUCH nicer

It works like a charm !

Thanks for the howto, however I got those errors with the make commands;

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.2.3/../../../../lib/libftgl.a(FTFont.o): relocation R_X86_64_32S against `vtable for FTFont' can not be used when making a shared object; recompile with -fPIC

make[2]: *** [projectM-engine/libprojectM.so.2.00] Fel 1
make[1]: *** [projectM-engine/CMakeFiles/projectM.dir/all] Fel 2

Any ideas? Really wanna get this to work, thanks in advance!

[Hells_Dark]

I've got something annoying :
When i fullscreen projectM, the mouse disappears.
And then, never goes back..

[Jojo12a]

compile with "-DUSE_FTGL=OFF" because the ubuntu ftgl-dev package isn't working correctly with projectM...

struktured, not sure if you're still following, but I'm getting the same "terminate called after throwing an instance of 'int'" error. Here's the backtrace after crash switching to next vis:

Your instructions worked fine on previous install, but getting that error on current fresh install.

Thanks!
