           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

Linking against a built libWPEWebKit-0.1.so is not posible when WPE is build with:

  -DENABLE_VIDEO=OFF
  -DENABLE_WEB_AUDIO=OFF


Error:

platform/mediastream/libwebrtc/LibWebRTCProviderGlib.cpp only is added if `ENABLE_VIDEO OR ENABLE_WEB_AUDIO` (L1 in Source/WebCore/platform/GStreamer.cmake) so `WebCore::LibWebRTCProvider::webRTCAvailable() and `WebCore::LibWebRTCProvider::create()' are not defined and the shared library is incomplete.

Other considerations:

    Actual CMake flags used for tests:

        -DPORT=WPE \
        -DCMAKE_BUILD_TYPE=Release \
        -DENABLE_ACCELERATED_2D_CANVAS=ON \
        -DENABLE_DEVICE_ORIENTATION=OFF \
        -DENABLE_ENCRYPTED_MEDIA=OFF \
        -DENABLE_FETCH_API=ON \
        -DENABLE_GAMEPAD=OFF  \
        -DENABLE_GEOLOCATION=OFF \
        -DUSE_GSTREAMER_GL=OFF \
        -DENABLE_MEDIA_SOURCE=OFF \
        -DENABLE_REMOTE_INSPECTOR=ON \
        -DENABLE_VIDEO=OFF \
        -DENABLE_VIDEO_TRACK=OFF \
        -DENABLE_WEB_AUDIO=OFF \
        -DENABLE_WEB_CRYPTO=OFF \
        -DUSE_WOFF2=ON


    WebRTC is not enabled in the CMake configuration:

        cat build/cmakeconfig.h | grep RTC
        #define ENABLE_WEB_RTC 0
        #define USE_LIBWEBRTC 0
        #define WEBRTC_WEBKIT_BUILD 0
