[webkit-help] /usr/local/bin/xmllint: undefined symbol: xmlMemSize when compiling webkitgtk-2.46.3

[Raphy Ubuntu]

Hi!

During compilation of the latest stable release webkitgtk-2.46.3 I'm
getting this error:

raphy at raohy:~/Downloads/webkitgtk-2.46.3$ cmake --build builddir/

    [ 92%] Built target WebCore_CopyPrivateHeaders
    [ 92%] Built target WebKit-forwarding-headers
    [ 92%] Generating ../../WebKitGTK/DerivedSources
    /ModernMediaControlsGResourceBundle.c,

    /ModernMediaControlsGResourceBundle.c.deps
     /usr/local/bin/xmllint: symbol lookup error: /usr/local/bin/xmllint:
undefined symbol: xmlMemSize

/home/raphy/Downloads/webkitgtk-2.46.3/builddir/WebKitGTK/DerivedSources
/ModernMediaControlsGResourceBundle.xml: Child process exited with code 127.


But a suitable xml2 library was detected:
