macOS: libmediainfo problem with 25.03

[mlaggner]

I saw that the macOS .dylib of libmediainfo is half the size compared to other versions. After digging a bit deeper, I saw that the x86_64 part is not completely available in the .dylib itself:

otool -vf libmediainfo.0.dylib
Fat headers
fat_magic FAT_MAGIC
nfat_arch 2
architecture x86_64
    cputype CPU_TYPE_X86_64
    cpusubtype CPU_SUBTYPE_X86_64_ALL
    capabilities 0x0
    offset 16384
    size 22832
    align 2^14 (16384)
architecture arm64
    cputype CPU_TYPE_ARM64
    cpusubtype CPU_SUBTYPE_ARM64_ALL
    capabilities 0x0
    offset 49152
    size 8477280
    align 2^14 (16384)

Have a look at the size of the x86_64 part and compare it to the arm64 part.

When analyzing the 24.12 version, this looks quite different:

otool -vf libmediainfo.0.dylib
Fat headers
fat_magic FAT_MAGIC
nfat_arch 2
architecture x86_64
    cputype CPU_TYPE_X86_64
    cpusubtype CPU_SUBTYPE_X86_64_ALL
    capabilities 0x0
    offset 16384
    size 9084928
    align 2^14 (16384)
architecture arm64
    cputype CPU_TYPE_ARM64
    cpusubtype CPU_SUBTYPE_ARM64_ALL
    capabilities 0x0
    offset 9109504
    size 8438896
    align 2^14 (16384)

And looking at the project tinyMediaManager I also see that there are problems on x86_64 loading libmediainfo - the error Failed to load mediainfo - 'Error looking up function 'MediaInfo_Option': dlsym(0x471b8b80, MediaInfo_Option): symbol not found' appears in the x86_64 version, but in the arm64 version everything works as expected

The one from MediaArea build farm is too small for the x86_64 part but the one built on GitHub Actions seems okay.

I made a test run here: https://github.com/cjee21/MediaInfo/actions/runs/14535214318 Look at the Check libmediainfo.0.dylib and Test CLI steps output for both arm64 (macos-latest) and x86_64 (macos-13).

Yeah - looks like the test run did the build correctly. The file sizes are similar to the version 24.12

Do you plan to re-release 25.03 or is a new release just around the corner?

or is a new release just around the corner?

End of month. Not sure it is worth it to rebuild the previous version.

Should be fixed in latest snapshot

The libtool script generated in our Linux build environment seems to be causing this problem with recent versions of Xcode.

Thanks - since the end of the month is just around the corner (and I will not release a new release in the next days), I will just wait for the new release of libmediainfo 👍
