Flame building issues, v4l includes?


(Benjamin Podszun) #1

Hi.

I tried posting this to the ML as well, but a) that was withheld for moderation and b) the ML seems a lot less frequented. I apologize if this ‘cross post’ is against the etiquette here.

I’m building on Arch Linux, after a long hiatus/switching machines, and my build fails in objdir-gecko/media/webrtc/trunk/webrtc/modules/modules_video_capture_module_internal_impl with

But … the file in question (device_info_linux.cc) has these includes

#if defined(__NetBSD__) || defined(__OpenBSD__)
#include <sys/videoio.h>
#elif defined(__sun)
#include <sys/videodev2.h>
#else
#include <linux/videodev2.h>
#endif

and /usr/include/linux/videodev2.h line 2243 is

#define VIDIOC_ENUM_FRAMESIZES _IOWR('V', 74, struct v4l2_frmsizeenum)

What am I missing? Thanks in advance,
Ben

You need to apply the patches from https://bugzilla.mozilla.org/show_bug.cgi?id=1304965


(Benjamin Podszun) #3

Whoa. That was insanely fast. Very much appreciated and I apologize that I didn’t see that bug earlier. I did a general “What could I do wrong here” type of search, but didn’t search bugzilla. My bad.

Appreciated!


(Benjamin Podszun) #4

That patch allowed me to build successfully and I could flash the result. Unfortunately that is broken (screen stays off, logcat shows a looping SIGSEGV. I … assume that’s because building ‘master’ isn’t a good idea and that this isn’t a problem on my side anymore, right? After the SIGSEGV everything dies

I/ServiceManager( 191): service ‘android.security.keystore’ died
6 I/ServiceManager( 191): service ‘SurfaceFlinger’ died
5 I/ServiceManager( 191): service ‘permission’ died
4 I/ServiceManager( 191): service ‘display.qservice’ died
3 I/ServiceManager( 191): service ‘media.audio_flinger’ died
2 I/ServiceManager( 191): service ‘media.player’ died
1 I/ServiceManager( 191): service ‘media.camera’ died
0 I/ServiceManager( 191): service ‘media.audio_policy’ died

and the process starts all over again.


(Fabrice) #5

You should use the ./run-gdb.sh script to start b2g and get a backtrace to track the issue.


(Benjamin Podszun) #6

Is this helpful? I’m - kinda lost. Also - is this thread the right way to ask about this issue?
Screen stays dark (only the ‘charging/connected’ LED is on), logcat repeats and so I assume the bt would repeat as well.

(gdb) c
Continuing.
