Arch Linux User Repository

@dbermond: I did that (git fetch origin for all repos) and ran makepkg. Exactly the same result: mv: cannot stat '/home/kau/.cache/yay/libjxl-git/pkg/libjxl-git/usr/share/java/org.jpeg.jpegxl.jar': No such file or directory

I want to point out the content of src/libjpeg/tools/CMakelists.txt (line 418-468). Theoretically, JPEGXL_ENABLE_JNI is set by src/libjxl/CMakeLists.txt which should result in the jar file being built, but it isn't. My java-environment package is "21.u35-3" and its official package name is listed as 'jdk-openjdk'.

My conclusion is there is either some hidden java dependency which is not installed, or perhaps jdk-openjdk does not provide the java-environment dependency in exactly the right way for the detection system to conclude 'yes, Java is available'.

Please remove replaces directive. Thank you. (No need to reply via comment; AUR now sends commit notifications.)

@0ion9 AUR helpers are not supported, use makepkg. Also, make sure that you have an updated checkout of this git repository.

"building fine for me" ? Not sure what to say to that, other than I tried a clean rebuild and still got the same error. At least I managed to capture it this time:

[...]
-- Installing: /home/me/.cache/yay/libjxl-git/pkg/libjxl-git/usr/bin/cjpegli
-- Installing: /home/me/.cache/yay/libjxl-git/pkg/libjxl-git/usr/bin/djpegli
mv: cannot stat '/home/me/.cache/yay/libjxl-git/pkg/libjxl-git/usr/share/java/org.jpeg.jpegxl.jar': No such file or directory

(slightly censored). I guess I can try a different package builder, but I think yay just calls makepkg.

@0ion9 I've just checked, and the package is building fine for me. No problems in the install stage.

@flannelhead upstream does not claim that jpegli is a replacement for libjpeg-turbo (at least not currently), but they say that it is compatible with libjpeg 6 (libjpeg.so.62), both in API and in ABI. Being such, I think we cannot assume it to be interchangeable with libjpeg-turbo. Also, it lacks important files shipped by libjpeg-turbo, like libturbojpeg.so, jerror.h, jpegint.h and turbojpeg.h. Since libjpeg-turbo has mostly become the standard in jpeg API nowadays, we cannot simply add {provides,conflicts}=('libjpeg'), as it's not true and probably will break applications expecting specific libjpeg-turbo functionality and files. Changing the default library soversion numbers also looks bad. What we could do is package it as a provider for libjpeg6, but I'm not sure if this would be useful, as currently there is only one application in the official repositories that depends on it.

Build currently fails in the install phase. Seems to be looking for a jar file belonging to libjxl and not finding it.

Since upstream CI seems to be completing successfully, I suspect the problem may be in the PKGBUILD (line 90?)

Now that upstream has jpegli that is a drop-in replacement for libjpeg, it would be neat to have that packaged too.

I managed to build a package containing jpegli by adding the following to the PKGBUILD:

-DJPEGXL_INSTALL_JPEGLI_LIBJPEG='true' \
-DJPEGLI_LIBJPEG_LIBRARY_VERSION='8.2.2' \
-DJPEGLI_LIBJPEG_LIBRARY_SOVERSION='8'

Then of course proper conflicts and provides entries would have to be added. Perhaps the drop-in should be a package of its own?

Thanks @dbermond for maintaining the PKGBUILD. Would you be interested in making those PKGBUILD modifications?

Many thanks @dbermond, it builds again.
