Failure to build for flame, v4l include?

[benjamin...@gmail.com]

Hi.

Trying to revive my flame, I fail to build (on Arch Linux). The script stops at this in objdir-gecko/media/webrtc/trunk/webrtc/modules/modules_video_capture_module_internal_impl

Looking at device_info_linux.cc I see that this includes

// v4l 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 has the following at line 2243

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

Now, at this point I'm lost. Any idea why this might fail?

Thanks in advance,
Ben

Hi Benjamin,

I guess you got your answer from the discourse thread?

The discourse thread/you helped me fix this error, yes.

I'm still unable to actually run that build, but I'm trying to learn as I go and - I posted all the details on discourse anyway.

Thanks a lot, both for approving the message and helping me over there.

Hi,

> I guess you got your answer from the discourse thread?

I've been trying to build for flame and I posted here the problems I
had. But there were no answers. Is everything happening in discourse,
should I go there?

Could you share the discourse link again?

Thanks, Eduardo.

yes, most activity has moved to discourse now.
