https://github.com/kornelski/pngquant/blob/3.0.3/CHANGELOG Since 3.0.0, pngquant uses libimagequant 4.x, which is a Rust rewrite, and and switches the build system from make to Cargo. The `pngquant` executable is now a Rust wrapper around `pngquant.c`, which in turn interfaces with libimagequant via the `imagequant_sys` crate, which exports a C API.[1] The CLI seems unchanged. Upstream lacks a Cargo.lock[2], so I generated one and patched it in. Set `doCheck = false;` as there are no Rust-based tests. `test/` was previously part of the make-based workflow (which is gone with pngquant 3.x) and looks like it isn't meant for pngquant 3.x anyway (as `test.sh` executes `$BIN --version 2>&1 | fgrep 2.`). `$ nix build .#pkgsCross.raspberryPi.pngquant` succeeds[3]; remove the workaround originally introduced in [4]. Notes on dependencies: - While nixpkgs package libimagequant on its own, pngquant depends on a specific vendored version - pngquant 3.x depends on the libpng-sys and lcms2-sys crates, which provide bindings to the respective C libraries. If those are not provided by the system at build time, vendored versions of them will be built and statically linked; libpng 1.6.37 and LCMS 2.15, respectively [1] See also: https://github.com/kornelski/pngquant/issues/368#issuecomment-1542507114 [2] See also: https://github.com/kornelski/pngquant/issues/347 [3] New SSE flag decision logic: https://github.com/kornelski/pngquant/blob/3.0.3/rust/build.rs#L31 [4] https://github.com/NixOS/nixpkgs/pull/145672
