termux-api fails with a linker error

[igor725]

Problem description termux-api binary not working at all in the proot container

Steps to reproduce

1. termux-chroot bash
2. /usr/libexec/termux-api
3. Linker error occurs (Error preloading public library liblistenjni.qti.so, library not found)

Expected behavior termux-api doesn't throw an linker error, just like outside proot

Doesn't seem like this has anything to do with termux-api. Something is trying to LD_PRELOAD liblistenjni.qti.so for some reason, and not finding it

[igor725]

There is only libtermux-exec.so in the LD_PRELOAD. The thing is that I don't have liblistenjni.qti.so anywhere, neither in /system or /vendor, so I can't even add it to LD_LIBRARY_PATH. gdb says that termux-api hangs on __accept4 function.

[Grimler91]

Seems like xiaomi should have it in /system_ext or something like that

Mixing proot libraries and android libraries is messy so not sure if we want to try to support termux-api for proot

[igor725]

Oh, didn't notice this one. And yes, I found this library in /system_ext. I'll try to figure it out myself, thanks.

[igor725]

Looks like mounting /system_ext fixes this issue. I didn't even have to change LD_LIBRARY_PATH, I just added ARGS="$ARGS -b /system_ext:/system_ext" to /usr/bin/termux-chroot and it worked.

Great :+1:
