Source: nvidia-texture-tools Severity: normal Dear Maintainer,
nvidia-texture-tools contains an embedded copy of libsquish: in src/nvtt/squish 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 nvidia-texture-tools version was forked around v1.7. It has a 1-character change which does not obviously have a reason: "Vec4 m_unweighted[16];" changed to "Vec4 m_unweighted[17];" in fastclusterfit.h. This change has not been included, because it's not in any of the other versions, and seems odd, so if there really is a reason for this then then debian package should be updated. 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 nvidia-texture-tools 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
