  • Linking error stdc++

    11 mars 2016, par Per M.

    Why am I having these linking errors ?

    Here is a short sample of link errors, there are hundreds similar :

    I am on Debian 7, using Clang compiler. The code is built using a makefile system, the following compiler flags is used

    CXXFLAGS = -g -I /opt/intel/composer_xe_2015.1.133/ipp/include/ -Wno-deprecated -D_GNU_SOURCE  -D_REENTRANT -D__STDC_CONSTANT_MACROS -I/usr/include/postgresql/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtX11Extras/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtWidgets/ -I/usr/local/Qt/5.2.1/gcc_64/include/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtGui/ -fPIC -fPIE -I/home/go/ffmpeg_build/include/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtCore/  -fPIC -fPIE -I/home/go/ffmpeg_build/include/libavcodec -I/home/go/ffmpeg_build/include/libavformat/

    If I add -lstdc++ to my compiler options, FFmpeg gives link errors instead. I have wrapped FFmpeg includes in extern "C" as I have seen elsewhere on this site. It doesn’t help. But I don’t think that is the problem here.

    FFmpeg is compiled as dynamic libs from source. (I had the same behavior when I linked static libs.)

    I have checked the FFmpeg libs with ldd and the dependencies is in place. I have checked for 32/64 mix-ups but it all seems to be 64 as it should be.

    The example contained in FFmpeg source compiled and linked fine.

    Is there any other external part that could give these errors ? C++11 ? Any indication could help. Thanks.

    dxva2 : allow an empty array of ID3D11VideoDecoderOutputView

    We can pick the correct slice index directly from the ID3D11VideoDecoderOutputView
    
casted from data[3].
    

    Also added myself as maintainer for DXVA2 and D3D11VA.
