AVFoundation indev cannot enabled when configure ffmpeg compile in Mac OS Marverick

[xnohat]

Summary of the bug:

AVFoundation indev cannot enabled when configure ffmpeg compile in Mac OS Marverick

How to reproduce:

Follow the guide at ​https://trac.ffmpeg.org/wiki/MacOSXCompilationGuide

./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-indev=avfoundation

But after ./configure script run, it not enable avfoundation indev

Enabled bsfs:
aac_adtstoasc		imx_dump_header		mp3_header_decompress
chomp			mjpeg2jpeg		noise
dump_extradata		mjpega_dump_header	remove_extradata
h264_mp4toannexb	mov2textsub		text2movsub

Enabled indevs:
lavfi

Enabled outdevs:
sdl

Problem from this line in ./configure:

# these are off by default, so fail if requested and not available
enabled avfoundation_indev && { check_header_oc AVFoundation/AVFoundation.h || disable avfoundation_indev; }

It disabled permanently avfoundation_indev

Patch suggest:

enabled avfoundation_indev

Please run ./configure and provide (the relevant part of) the file config.log.

Hi cehoyos,

I attached with this ticket config.log of configure arg:

./configure --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-indev=avfoundation

AVFoundation compiles fine under Mavericks here.
So this looks like an Xcode issue.
What Xcode version are you using?
And on which Mac? Does it have an integrated Camera?

[Carl Eugen Hoyos]

This is using an old compiler (see ticket #3569), workaround is apparently to install current XCode:

$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

[Carl Eugen Hoyos]

Could you test if attached patch makes any difference? Does it allow autodetection and build?

[Carl Eugen Hoyos]

I am able to reproduce the problem: AVFoundation cannot be built with Xcode 4.6.3 - gcc 4.2.1 llvm 2336.11.00 - on Mavericks, workaround is to install a more recent version of Xcode. I will attach a patch that fixes the issue here, tested with both the failing gcc version and clang 503.0.40.

(The patch I attached a week ago does not help.)

i face the problem under macosx 109 and gcc version 5.2.0 (MacPorts gcc5 5.2.0_0) .
if the clang of apple is used, OK.
