Undefined symbol: xmlMemSize when compiling webkitgtk-2.46.3

Platform

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

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

[ 92%] Built target WebCore_CopyPrivateHeaders

/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:

What am I missing ? How to make it work?

xmlMemSize was introduce in d7daf9fd which is available from libxml2 version 2.11.0.

Ubuntu 24.04 still uses an older 2.9.14 version.

So, it appears you’ve built and installed a much recent xmllint in a non-standard path, which tries to use the system libxml2, which is still at 2.9.14. Hence the failure. Use system libxmllint or update LD_LIBRARY_PATH if you want the custom built xmllint.

Also, you’ve posted the same question in multiple places in the past hour (which I think is not good practice).
