@ai-ecoverse/wasm-imagemagick-relink
The LGPL relink kits of
@ai-ecoverse/wasm-imagemagick
and
@ai-ecoverse/wasm-imagemagick-heif
of the same version as this package. Their bin/magick.wasm links its
libraries statically, among them GNU libiconv (LGPL-2.1-or-later, through
libxml2) and, in the heif build, libheif and libde265 (LGPL-3.0-or-later).
With a kit you can link magick again against your own build of any of
them. You don't need this package to run ImageMagick (homescoop#593).
Relinking
| Kit | For |
|---|---|
share/imagemagick/relink/ | @ai-ecoverse/wasm-imagemagick |
share/imagemagick-heif/relink/ | @ai-ecoverse/wasm-imagemagick-heif |
Each kit holds magick's objects (magick.a, libMagickCore-7.Q16HDRI.a,
libMagickWand-7.Q16HDRI.a), the static libraries of the link
(liblcms2.a, libtiff.a, libjpeg.a, libfreetype.a, libpng16.a,
libz.a, libwebpmux.a, libwebpdemux.a, libwebp.a, libsharpyuv.a,
libopenjp2.a, libxml2.a, libiconv.a, the slicc shims libslicc-cli.a
and libslicc_cred.a), the link flags (ldflags.txt, with the
--js-library files in js/), relink.sh, the notices of its build
(THIRD-PARTY-NOTICES.md) and kit.json: the sha256, size and import and
export hashes of the bin/magick.wasm these objects made.
relink.sh <out-dir> [dir] links magick and magick.wasm into
<out-dir>. A static library in dir with the name of one of the kit's
replaces the kit's copy. For the heif kit, dir is required and also holds
libheif, libde265 and dav1d (libheif.a, libde265.a, libdav1d.a,
from @ai-ecoverse/wasm-libheif's lib/ or your own build). With
Emscripten 4.0.23:
npm pack @ai-ecoverse/wasm-imagemagick-relink@<version> && tar xzf ai-ecoverse-wasm-imagemagick-relink-*.tgz
mkdir -p /tmp/libs && cp /path/to/your/libiconv.a /tmp/libs/
bash package/share/imagemagick/relink/relink.sh /tmp/relinked /tmp/libs
cp /tmp/relinked/magick /tmp/relinked/magick.wasm node_modules/@ai-ecoverse/wasm-imagemagick/bin/
The kits come from the same build as the runtime packages:
build.sh
runs packages/imagemagick/build.sh and packages/imagemagick-heif/build.sh
and keeps their objects. ladder-pr relinks both kits on every build
(cert/relink-check.mjs), with libiconv.a from @ai-ecoverse/wasm-libiconv,
and checks the result against kit.json.
