JXL tools build number doesn't exist

[lopes143]

"Build JPEG-XL Tools" is enabled, so m-a_s build JXL tools (cjxl.exe, djxl.exe, jxlinfo.exe).

However, when I open cjxl.exe on terminal, it says "JPEG XL encoder v0.12.0 d2a9717 [AVX2,SSE4,SSE2]"

Version 0.12.0 doesn't even exist: lastest is 0.11.1, but since build it's from master, the number may be incorrect.

But I tried to search in "libjxl" repository, and didn't find any commit with the hash "d2a9717". So what does m-a_s build ?

I found this bc 0.11.1 support EXR files but media-autobuild's don't.

Edit: I built jxl tools from master on Linux (following their building guide), and the build number is indeed 0.11.1, and it supports EXR.
I really can't find out what media-autobuild is using to build jxl...

The different commit hash is due to mabs patching libjxl with https://raw.githubusercontent.com/m-ab-s/mabs-patches/master/libjxl/0001-brotli-link-enc-before-common.patch for brotli due to quirks of static linking. The patch might not be necessary anymore, but I haven't tested it recently without it.

0.12.0 is from https://github.com/libjxl/libjxl/blob/dc8438add651ef5b2ef4cf9b44a495f7a6d6727d/lib/CMakeLists.txt#L6-L10. I'm guessing you built it on linux using a tarball or with the latest tag rather than from git.

EXR stuff is probably because we don't have openexr enabled. Based on https://github.com/libjxl/libjxl/blob/dc8438add651ef5b2ef4cf9b44a495f7a6d6727d/lib/jxl_extras.cmake#L89C5-L89C26, it may be as simple as installing the package from pacman and then making sure JPEGXL_ENABLE_OPENEXR is enabled with cmake.

Thank you for your response. In fact, I was analyzing jxl tools from my distro packages and not what I built, so that's why the wrong versions. The source built is really 0.12.0.

I tried to enable openexr flag in build script, but it ended missing libraries, so that will be tough to make it work.
