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

[eddier]

Running Maverick(in mint 10). I see projectM-pulseaudio is in the repo's but I decided to try this install and enable cg in ccmake, Crunch!

/home/eddie/projectm/projectM-Trunk/src/projectM-pulseaudio/qprojectM-pulseaudio.cpp: In function ‘std::string read_config()’:
/home/eddie/projectm/projectM-Trunk/src/projectM-pulseaudio/qprojectM-pulseaudio.cpp:170: error: ‘mkdir’ was not declared in this scope
make[2]: *** [projectM-pulseaudio/CMakeFiles/projectM-pulseaudio.dir/qprojectM-pulseaudio.o] Error 1
make[1]: *** [projectM-pulseaudio/CMakeFiles/projectM-pulseaudio.dir/all] Error 2
make: *** [all] Error 2

Anyone provide a clue,I tried to decipher it but its a bit gobbledegook to me,it appears to be a missing directory??

Try running "sudo apt-get build-dep projectm-pulseaudio"
and rerunning make.

fixed: open qprojectm-pulseaudio.cpp in a text editor, go to line 169 and comment it out. Then it will compile. Just make sure that ~/.projectM/config.inp exists, cause I am not a C++ programmer, so I don't know how to completely fix the situation, just kinda hack around it Now I get CG too lol

I found the fix for this problem. If you read the manual for the mkdir() function (type "man 2 mkdir"), you'll see that this function requires <sys/types.h> and <sys/stat.h>. So do the following:

1) Open "src/projectM-pulseaudio/qprojectM-pulseaudio.cpp" in a text editor.
2) Under line 46 ("#include <math.h>") add the following two lines:

#include <sys/types.h>
#include <sys/stat.h>

3) Save and exit. It should now compile.

I've submitted the patch to the projectM tracker: https://sourceforge.net/tracker/?fun...01&atid=637262

You might want to submit this upstream

Good point. I just submitted the patch to the projectM tracker: https://sourceforge.net/tracker/?fun...01&atid=637262

hopefully it gets committed

there hasn't been much/any projectM svn activity in a while iirc

Hi, I managed to get projectm installed but when I tried it I realized that it only shown a black screen, I hope somebody have any idea on how to fix this, PS. Im using ubuntu 10.10.

how did you install it? In Ubuntu 10.10 all you have to do is type

sudo apt-get install projectm-pulseaudio

in a terminal.

hi, I'm in a similar situation:
I installed it from the repos and it opens and shows the plugins ok, but even though i configured the right pulseaudio entry it just looks like there's no audio going through it.

then i downloaded the .deb from page 28 and the projectm-test works, but the projectm-pulseaudio one doesn't!

any ideas??

I'm using rhythmbox for playing audio

thanks!
