Installation fails on OS X #12

Sajonara · 2015-02-10T06:04:43Z

Hello,

I would like to thank you for p2pvc but I cannot install it on OS X (10.10.3 Beta 1). I have Homebrew installed and did install the depending packages like so, because at least with one package I got an error notice when I first tried to "make" p2pvc:

brew install homebrew/science/opencv
brew install pulseaudio
brew install ncurses

When all those installs are finished I'm still confronted with error messages, when I try to "make" p2pvc:

src/p2plib.c:275:7: warning: implicit declaration of function 'clock_gettime' is invalid in C99 [-Wimplicit-function-declaration]
      clock_gettime(CLOCK_MONOTONIC, &prevPacket);
      ^
src/p2plib.c:275:21: error: use of undeclared identifier 'CLOCK_MONOTONIC'
      clock_gettime(CLOCK_MONOTONIC, &prevPacket);
                    ^

      clock_gettime(CLOCK_MONOTONIC, &prevPacket);
                    ^

Any help would be appreciated.

Kind regards.

hey, try pulling from the portaudio branch. I've successfully been able to get it working on my OS X machine using that branch. You'll also need to install portaudio: brew install portaudio

git fetch; git checkout portaudio; git pull; make clean; make

Sajonara · 2015-02-10T06:09:12Z

I'm sorry @emgram769 I tried as you said but it still outputs these errors.

emgram769 · 2015-02-10T06:10:46Z

what is the output of git branch?

mofarrell · 2015-02-10T06:28:28Z

try this. it will directly clone the specified branch
git clone -b portaudio https://github.com/mofarrell/p2pvc.git
then
make
Also make sure you have opencv properly installed.

hzwzw · 2015-02-10T07:46:19Z

clock_gettime() is not supprted by mac os , can i use gettimeofday() instead?
if (delta == -1) {
gettimeofday(&prevPacket, 0);
// clock_gettime(CLOCK_MONOTONIC, &prevPacket);
delta = 0;
} else {
gettimeofday(&currPacket, 0);
// clock_gettime(CLOCK_MONOTONIC, &currPacket);
delta = currPacket.tv_nsec - prevPacket.tv_nsec;
// clock_gettime(CLOCK_MONOTONIC, &prevPacket);
gettimeofday(&prevPacket, 0);
}

mofarrell · 2015-02-10T07:50:11Z

Probably better using http://stackoverflow.com/questions/5167269/clock-gettime-alternative-in-mac-os-x
We will get to this once one of us can get our hands on a mac to test this with.

Alternatively you could try checking out a revision without the bandwidth information.

mofarrell · 2015-02-10T08:04:15Z

This has now been disabled for OSX on the portaudio branch until we get someone to look at it. If you pull the latest it should compile.

hzwzw · 2015-02-10T08:08:17Z

i change the code by using http://stackoverflow.com/questions/5167269/clock-gettime-alternative-in-mac-os-x
and compile is ok
and when i input the command "./p2pvc 127.0.0.1 -v" , nothing happened .
how can i help you test @mofarrell

emgram769 · 2015-02-10T08:09:25Z

what version of OS X are you running?

hzwzw · 2015-02-10T08:10:05Z

os 10.10.1 @emgram769

Sajonara · 2015-02-10T08:12:07Z

I downloaded the newest release and tried to "make" it. But the errors remain. I will be following this project and see what future releases will offer me. I'm on 10.10.3 Beta 1.

emgram769 · 2015-02-10T08:13:23Z

hopefully I'll be able to roll out some binaries for OS X soon, but there seem to be issues with 10.10's networking.

jirutka · 2015-02-10T10:41:14Z

emgram769 · 2015-02-10T15:19:21Z

looks like a bad #ifdef was the cause. it may compile now, but I will update this when I test on a mac.

Pinwheeler · 2015-02-10T15:27:45Z

using git clone -b portaudio https://github.com/mofarrell/p2pvc.git I am able to make the project without the clock errors. Execution as ./p2pvc 127.0.0.1 -v causes the application to hang with no error messages, however.

jirutka · 2015-02-10T17:04:50Z

Same as @Pinwheeler.

itsprdp · 2015-02-10T17:11:09Z

Same as @Pinwheeler

damianesteban · 2015-02-10T19:06:19Z

Same as @Pinwheeler unfortunately. :(

emgram769 · 2015-02-10T19:07:58Z

the thought is that yosemite is killing sockets with large UDP packets. I've just changed the way that the packets are sent to reduce the size of any individual one. can I confirm that most (if not all) of you are on yosemite? I'm not sure if the newest commit to portaudio will solve any of this, but it may help

jirutka · 2015-02-10T19:10:21Z

I’m on Mavericks (I don’t like Yosemite 😼).

itsprdp · 2015-02-10T19:11:09Z

@emgram769 I'm on Yosemite 10.10.2.
I pulled the latest from portaudio. Still the same. It's not working.

I used to have the same issue as @jirtuka

jirutka · 2015-02-10T21:24:42Z

I’ve just tried the last revision (5fb2904) of the portaudio branch. The same warnings as @Haroenv and…

$ p2pvc git:(portaudio) ./p2pvc 127.0.0.1 -v
An error occured while using the portaudio stream
Error number: -9998
Error message: Invalid number of channels

RileyMills · 2015-02-10T22:32:56Z

Also getting the same massive wall of warnings like @Haroenv (commit 4a34900). I don't ever get an error message, but noting happens when I try to run the program. I believe the audio system is working, as I'll start getting feedback if I leave my speakers on, but the camera never starts.

damianesteban · 2015-02-10T23:05:18Z

When I start it up on my Mac (OS X 10.10.2) I get the audio feedback from my mic, and no video. Going to test it out with a friend shortly.

RileyMills · 2015-02-10T23:13:00Z

I've done some debugging on my end, and as far as I can tell argv is getting passed in correctly, but the getopt() loop in p2pvc.c never actually finds any args. I have a print statement in the main while portion of the loop that never gets hit:

printf("argc: %d \n", argc);
  printf("argv:\n");

  int i;

  for (i = 0; i < argc; i++) {
    printf("%s\n", argv[i]);
  }

  printf("\n");

  while ((c = getopt (argc, argv, "bvd:A:V:")) != -1) {
    printf("HI\n");
    switch (c) {
      case 'v':
        spawn_video = 1;
        break;
      case 'A':
        audio_port = optarg;
        break;
      case 'V':
        video_port = optarg;
        break;
      case 'd':
        get_dimensions(optarg, &width, &height);
        vopt.width = width;
        vopt.height = height;
        break;
      case 'b':
        vopt.disp_bandwidth = 1;
        break;
      default:
        break;
    }
  }

  fprintf(stdout, "Checking Video.\n");

results in:

$ ./p2pvc 127.0.0.1 -v
Starting up.
argc: 3 
argv:
./p2pvc
127.0.0.1
-v

Checking Video.
Not starting Video.
^CUser defined signal 1: 30

Edit: I suppose I should clarify, I'm on OSX Yosemite 10.10.2

Update:

Just to test things I hardcoded the application to assume I requested video, and video output is working just fine. Of course, I cannot override the default dimensions (As all args are being ignored) but I can get the default video output working.

jirutka · 2015-02-11T01:57:47Z

Whoo, the last revision (4bc708d) finally works! 😸

However, video doesn’t look well, but it’s too late, maybe just insufficient light. I’ll try it tomorrow, also with another webcam.

mofarrell · 2015-02-11T03:03:50Z

PortAudio branch has been moved to master. Any new bugs with OSX should create a new issue.

jirutka · 2015-02-11T14:45:23Z

I’ve tried an external webcam with FullHD and it looks much better!

Haroenv · 2015-02-11T17:25:13Z

What font are you using? It looks fuller than mine . It's a bit dark now, but it didn't change that much when in daylight

emgram769 · 2015-02-11T17:30:24Z

you can now use custom ASCII with the -a flag, if you'd like to mess with different characters to better suit your font

jirutka · 2015-02-11T17:32:57Z

@Haroenv It depends on the used font, its size, spacing etc. I’ve used Courier New in the screenshot, it looks “fuller” than Monaco which I usually use.

Picture from my MacBook webcam is also quite dark, this one is from an external webcam.
