Please do not set LD_LIBRARY_PATH=/system/lib

defencedog commented 7 months ago

@truboxl I added that because ffmpeg will not work Your instructions work ... but now when I use ffmpeg

CANNOT LINK EXECUTABLE "ffmpeg": cannot locate symbol "_Z17createHeifDecoderv" referenced by "/system/lib/libhwui.so"...
truboxl commented 7 months ago

Please install libandroid-stub if it fixes your issue

defencedog commented 7 months ago

Thanks it works...

Biswa96 commented 7 months ago

May I ask how libandroid-stub fixed the ffmpeg issue? Ther error output has createHeifDecoder function which is not related to libandroid library.

sylirre commented 7 months ago

It is related but indirectly. libandroid.so has dependencies such as libhwui.so, the latter fails to resolve symbol due to library conflict - Termux have libraries with same name as Android, but they different internally causing stuff to break.

This is also why one should never set LD_LIBRARY_PATH in Termux. It messes up library search order. This variable was required for Termux running on legacy Android versions (5.x, 6.x).

Installing libandroid-stub cause ffmpeg to pick a stub version of libandroid.so that is present in Termux directories instead of Android system.

agnostic-apollo commented 7 months ago

The _Z17createHeifDecoderv symbol is provided by /system/lib[64]/libheif.so, which /system/lib[64]/libhwui.so depends on.

The termux libheif package also provides $PREFIX/lib/libheif.so.

Installing the libandroid-stub package shouldn't be required, my guess is that user has set LD_LIBRARY_PATH=/data/data/com.termux/files/usr/lib somewhere else, which causes $PREFIX/lib/libheif.so to be picked up instead of the system one.

This error was posted in https://www.reddit.com/r/termux/comments/17pxvw5/how_to_fix_this/ as well and unsetting LD_LIBRARY_PATH worked.

defencedog commented 7 months ago

@agnostic-apollo Problem has resurfaced with gtt. I had already installed libandroid-stub

CANNOT LINK EXECUTABLE "gtt": cannot locate symbol "_Z17createHeifDecoderv" referenced by "/system/lib/libhwui.so"...
truboxl commented 7 months ago

Can you help try rm $PREFIX/lib/libheif.so?

defencedog commented 7 months ago

@truboxl will not rm be dangerous what about renaming via mv?

truboxl commented 7 months ago

Unless you use packages from apt rdepends libheif then maybe. You can always restore by apt reinstall libheif.

agnostic-apollo commented 7 months ago

Also post output of echo LD_LIBRARY_PATH=$LD_LIBRARY_PATH after running it in the same shell in which error is triggered.

LD_LIBRARY_PATH=/data/data/com.termux/files/usr/lib:/data/data/com.termux/files/usr/local/lib

agnostic-apollo commented 7 months ago

That is your problem, find out where it is being set and remove the command, it should be empty on Android >= 7, termux does not set it by default. Also uninstall libandroid-stub with apt remove libandroid-stub and restore your $PREFIX/lib/libheif.so file.
