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

Quote:

---

I tried following this guide, but at the ccmake step it tells me that there's no CMakeList.txt

Any ideas?

---

Have you tried removing the Cmake cache as detailed in the tutorial? Please post the exact command output you get with this error.

The test if probably only useful for developers and debugging anyway, I might remove it from the tutorial.

EDIT: Has been removed from the tutorial, it was a useless additonal step anyway. Why care if the test fails as long as the actual program works?

I tried projectM-pulseaudio right after I tried projectM-test a few times. It segfaults as well.

digby@velvet:~$ projectM-test
dir:/usr/share/projectM/config.inp
reading ~/.projectM/config.inp
Screen Resolution: 1680 x 1050
MAX SAMPLES:2048
Segmentation fault
digby@velvet:~$ projectM-pulseaudio

MAX SAMPLES:2048
load config END

connectHelper: "alsa_output.pci_8086_24c5_sound_card_0_alsa_playb ack_0.monitor"
Segmentation fault

I'm using an ATI Radeon Mobility 9000.

I don't think I can help. Have you tried the IRC channel?

Sam

I can't really trace your problem without seeing it in gdb. Please change the CMAKE_BUILD_TYPE to "Debug", rebuild / install the project again, and run projectM-test via "gdb projectM-test". Then post the gdb's stack trace to the forum.

projectM-test works fine for me after compiling, projectM does nothing in terminal (bash: projectM: command not found).

I can select ProjectM in Mythtv settings.. but when I try and playback music the visualizations is just a white page. If I maximize the visualization i get a segmentation fault.

I have a Nvidia 6800GT

Edit.. I should say I'm using mythbuntu with xfce window manager

can anyone please tell me how to recompile it correctly (perhaps with different flags)?

I get this error when Making:

Thanks

Have you tried "-DCMAKE_BUILD_TYPE=RELEASE" mentioned here?

castles: The command is:

Code:

---

projectM-pulseaudio

---

Use tab autocompletion, it's much easier :-)

Thanks Sammy,

I was trying it with a lowercase "M" (might be worth updating the tutorial).

I get the following error now:

Code:

---

Connection failure: Connection refused
ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 808ea78. Receiver 'QProjectM_MainWindow' (of type 'QWidget') was created in thread 8064118", file kernel/qcoreapplication.cpp, line 274

Hi castles.

Tutorial updated, the other segfault you get is way beyond my abilities to decipher so we'd better wait for Struktured to comment.
