What should happen: system font config reads config files and finds existing binary caches ready for use and mmaps them. What looks like is happening for you is that reading the config files produced tons of errors that look like the config belongs to a different font config version, and no caching is in effect. Is it possible that your system doesn’t have the font config dev packages installed? I think then the build will fall back to building its own font config. Ldd would also tell linkage. |

I agree. This happened twice now and it's not really an exotic library anymore :-) |

When the fontconfig dev package is not installed, servo-fontconfig will fall back to building its own copy, which may be incompatible with what's on the system. The result is a horrible start-up time and this patch opts to instead require fontconfig to be available at build time and error out otherwise. Fixes issue #88

instead of servo-fontconfig servo-fontconfig statically links a vendored fontconfig library if fontconfig is not found by pkgconfig. Using a vendored fontconfig library instead of the system fontconfig library doesn't actually work well though: slint-ui/slint#88 Building a vendored copy of fontconfig is also problematic because fontconfig has a lot of C dependencies, which makes it difficult to cross compile the vendored copy of fontconfig: $ pkg-config fontconfig --static --libs -lfontconfig -lfreetype -lz -lbz2 -lpng16 -lm -lm -lz -lharfbuzz -lm -lglib-2.0 -lm -lpcre -lsysprof-capture-4 -pthread -lgraphite2 -lbrotlidec -lbrotlicommon -lxml2 -lz -llzma -lm Instead of using a vendored copy, with yeslogic/fontconfig-rs#12 yeslogic-fontconfig-sys will have a Cargo feature to dlopen fontconfig at runtime instead of linking it at build time. This is exposed in font-kit with the new source-fontconfig-dlopen feature, which is disabled by default. This feature makes it considerably easier to cross compile by avoiding the need to cross compile fontconfig and all its dependencies.
