Problem description

The libandroid-glob package version 0.7 contains a corrupted library file. The file /data/data/com.termux/files/usr/lib/libandroid-glob.so is only 1 byte instead of being a proper ELF library or symlink.

This causes link errors for any package that depends on libandroid-glob.so, including ffmpeg7, imagemagick, and potentially others.

Error message

CANNOT LINK EXECUTABLE "/data/data/com.termux/files/usr/bin/ffmpeg": "/data/data/com.termux/files/usr/lib/libandroid-glob.so" is too small to be an ELF executable: only found 1 bytes

What steps will reproduce the bug?

1. Update packages to get libandroid-glob 0.7 (built on 2025-11-10)
2. Install ffmpeg7: pkg install ffmpeg7
3. Try to run ffmpeg: ffmpeg -version
4. Observe the link error

Investigation

Checking the package contents shows the file is corrupted:

$ ls -lh /data/data/com.termux/files/usr/lib/libandroid-glob.so
-rw-------. 1 u0_a429 u0_a429 1 Nov 10 00:04 /data/data/com.termux/files/usr/lib/libandroid-glob.so

$ file /data/data/com.termux/files/usr/lib/libandroid-glob.so
/data/data/com.termux/files/usr/lib/libandroid-glob.so: very short file (no magic)

$ apt-get download libandroid-glob && dpkg-deb -c libandroid-glob_0.7_aarch64.deb | grep libandroid-glob.so
-rw------- 0/0               1 2025-11-10 00:04 ./data/data/com.termux/files/usr/lib/libandroid-glob.so

The package itself contains the corrupted 1-byte file.

Workaround

According to the package description, libandroid-glob should be a "Symlink to libc for compatibility". Creating this symlink manually fixes the issue:

rm /data/data/com.termux/files/usr/lib/libandroid-glob.so
ln -s /data/data/com.termux/files/usr/lib/libc++_shared.so /data/data/com.termux/files/usr/lib/libandroid-glob.so

After this workaround, ffmpeg and other affected packages work correctly.

What is the expected behavior?

The libandroid-glob.so file should be a proper symlink to a libc library, not a corrupted 1-byte file.

Related Issues

This might be related to #27185 which reports a similar issue with libandroid-posix-semaphore.so, also from packages built on 2025-11-10.

Suggested Fix

The package build script for libandroid-glob needs to be fixed to properly create the symlink instead of creating a 1-byte file. This likely happened during the build process on 2025-11-10.
