build: opt-in static libxml2 link via LIBXML2_STATIC (v0.3.13)#202
Merged
Conversation
When LIBXML2_STATIC is set, build.rs probes via pkg-config with .statik(true), emitting static=xml2 (+ transitive -lm), for a SONAME-independent self-contained downstream binary. Default (env unset) is unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Adds runtime (default) / static cargo features selecting how bindgen finds libclang. `--no-default-features --features static` routes bindgen to clang-sys/static for fully static / musl / Alpine builds where dlopen of libclang is unavailable. Orthogonal to LIBXML2_STATIC (which links libxml2 itself); together they close #110. Default behavior unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Opt-in static linking of libxml2, gated on the
LIBXML2_STATICenv var.When set (with
PKG_CONFIG_PATHpointing at a non-system prefix holding a PIClibxml2.a),build.rsprobes via pkg-config with.statik(true), emittingcargo:rustc-link-lib=static=xml2(+ transitive-lm). This lets a downstream binary avoid any runtimelibxml2.sodependency — relevant now that libxml2 2.14 bumped its SONAME.so.2→.so.16, so a dynamically-linked binary loads on only one side of that split.Default (env unset) is unchanged: a normal dynamic link against the host libxml2.
