JPEG XL support on Ubuntu

[cloudhopper]

I'm running XnViewMP 1.7.1 on Ubuntu 22.04. I've installed libjxl v0.10.2 DEB package from JPEG XL github site. JXL files open fine in Gnome's image viewer but not in XnViewMP. So, which version of the libjxl library is XnViewMP 1.7.1 looking for?

XnView MP don't use library from JPEG XL github. Now is used version 0.8.2, but I hope soon will be c0.10.2.

Thanks for your response. As a result I removed the 0.10.2 version of the libjxl package and installed the 0.8.2 version from the JPEG XL github. As before, Gnome's image viewer displayed a JXL image but XnViewMP did not

You mention that XnVIewMP does not use the libjxl library from the JPEG XL github. So, can you tell me which native library XnViewMP calls to decode JXL images? If I knew the name of the native library to which XnViewMP is trying to link to dynamically, I might be able to fix up the links in its library search path.

XnView use library from https://vcpkg.io
Until recently there was version 0.8.2, but now there is version 0.10.2. I'm waiting for Pierre to officially include it in the new version 1.7.2 of XnView MP.

I'll take a look at the vcpkg package manager site. Thanks very much for your help on this.
