Linker error compiling examples

[a-maier]

I get a linker error when trying to run any of the examples, e.g. with

cargo run --example render-glyph

The problem are undefined symbols in libfontconfig, for example

  = note: rust-lld: error: undefined symbol: XML_GetCurrentLineNumber
          >>> referenced by fcxml.o:(FcConfigMessage) in archive /usr/lib/x86_64-linux-gnu/libfontconfig.a
          >>> referenced by fcxml.o:(FcConfigMessage) in archive /usr/lib/x86_64-linux-gnu/libfontconfig.a

Here is the full log.

I am running Ubuntu 24.04 with pkg-config, libfreetype-dev, libfontconfig1-dev installed.

A workaround is to manually link to libexpat:

RUSTFLAGS="-lexpat" cargo run --example render-glyph
