Research direction

Start by reproducing ssimulacra2 input.png output.jxl with the reported libjxl-enabled build and inspect the image-loading path used for output.jxl. Improve the diagnostic output so the failed JPEG XL load reports its underlying reason, then verify the message while comparing a PNG with a JPEG XL image.

Description

I built ssimulacra with libjxl support:

ldd ssimulacra2
        linux-vdso.so.1 (0x00007fb2ad75e000)
        libjxl.so.0.12 => /root/tools/ssimulacra2/libjxl/build/lib/libjxl.so.0.12 (0x00007fb2ad000000)
        libjpeg.so.62 => /lib/x86_64-linux-gnu/libjpeg.so.62 (0x00007fb2ad5e6000)
        libpng16.so.16 => /lib/x86_64-linux-gnu/libpng16.so.16 (0x00007fb2ad5ae000)
        libjxl_cms.so.0.12 => /root/tools/ssimulacra2/libjxl/build/lib/libjxl_cms.so.0.12 (0x00007fb2ad57a000)
        libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fb2acc00000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fb2acf10000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fb2ad54b000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb2aca0b000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fb2ad760000)
        libbrotlidec.so.1 => /root/tools/ssimulacra2/libjxl/build/third_party/brotli/libbrotlidec.so.1 (0x00007fb2ad53c000)
        libbrotlienc.so.1 => /root/tools/ssimulacra2/libjxl/build/third_party/brotli/libbrotlienc.so.1 (0x00007fb2ac950000)
        libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fb2ad51a000)
        libbrotlicommon.so.1 => /root/tools/ssimulacra2/libjxl/build/third_party/brotli/libbrotlicommon.so.1 (0x00007fb2ad4f7000)

However when I try to compare a png to a jpeg xl I get this error:

ssimulacra2 input.png output.jxl
Could not load distorted image: output.jxl

Any way I could get a bit more logs on what exactly fails?
