Source: openimageio Severity: normal Dear Maintainer,
openimageio contains an embedded copy of libsquish: in tools/depends/native/libsquish-native I have recently packaged libsquish, and it is now avilable in the archive: https://tracker.debian.org/pkg/libsquish In doing this I examined all the embedded copies, checking them for changes, and have merged all the extra features into the Debian package. Thus it should be straighforward to start using the system library instead of the embedded copy, without any API changes. The changes have also been sent upstream and will hopefully appear in libsquish 1.14 at some point. The openimageio version was forked around v1.10 and has a couple of 1.13 features backported (extra perceptual metric). moving on to this 1.13 version of course includes this. Debian policy https://www.debian.org/doc/debian-policy/ch-source.html#s-embeddedfiles say that embedded copies should not be used if the library is available in Debian, and https://wiki.debian.org/EmbeddedCodeCopies gives a bit more background. I am not familiar with the openimageio build system, so have not attempted to provide a patch as that should be much easier for you, but of course I'll help if you need some. The full set of packages affected is: - nvidia-texture-tools 1.7 (src/nvtt/squish) - 0ad 1.7 (libraries/source/nvtt/src/src/nvtt/squish/) - spring 1.10 (rts/lib/squish) - openimageio 1.10+ (1.10+metric) (src/dds.imageio/squish) - xbmc 1.10+ (1.10+metric/BC45) (lib/libsquish) - kodi 1.10+ (1.10+metric/BC45) (tools/depends/native/libsquish-native) - mame 1.13+ (BC45) (3rdparty/bgfx/3rdparty/libsquish) Hope this is useful. Wookey
