Cause (Documented platform behavior): Documented prebuilt platform floors: Linux x64/ARM64 glibc >= 2.28 or musl >= 1.2.5; Linux x64 requires SSE4.2; other arches higher glibc. Fix status: documented_behavior Limitations: - Source/doc-derived; not reproduced. - exact string is generic; match together with product/context Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/lovell/sharp/51a990faa26ade5586a4934ac9673c98d8893326/lib/sharp.mjs (official_docs, unknown, documented_behavior): If messages match symbol not found|CXXABI_ on Linux, adds '- Update your OS:' with Found/Requires libc from the @img/sharp-libvips package config; for non-prebuilt platforms suggests manual libvips or @img/sharp-wasm32. - https://raw.githubusercontent.com/lovell/sharp/51a990faa26ade5586a4934ac9673c98d8893326/docs/src/content/docs/install.md (official_docs, unknown, documented_behavior): Prebuilt binaries list: Linux x64 (glibc >= 2.28, musl >= 1.2.5, SSE4.2), Linux ARM64 (glibc >= 2.28, musl >= 1.2.5), others; Node-API v9 runtime (Node >= 20.9.0).

Problem details

Observed symptom
Could-not-load error including a dlopen message with 'symbol not found' or 'CXXABI_' and Found/Requires libc lines.
Context
Product: sharp Component: prebuilt libvips binaries / libc requirement Operation: require('sharp') on older distros (CentOS/RHEL 7, Amazon Linux 2, old Alpine) or CPUs without SSE4.2 Affected versions: unknown Environment: Linux with old glibc/musl; old x64 CPUs Packages: sharp 0.35.x (current source); message family since 0.33 Trigger: Prebuilt sharp/libvips binary linked against newer libc/libstdc++ than the host provides.

Recommended action: Use a newer base image (glibc >= 2.28, e.g. Debian 10+/AL2023) or musl >= 1.2.5; otherwise build libvips from source (see building-from-source) or use the WebAssembly fallback (npm install sharp @img/sharp-wasm32). Option: Move to a supported libc or use Wasm [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. Rebase image on glibc >= 2.28 2. Or npm install sharp @img/sharp-wasm32 Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
