How to give a process its own libc?

Question

linux

There is a native library for Android that I'm trying to use via JNI on Linux (ubuntu 18.04). There are no specific dependencies there, except for the android libc (bionic).
And at startup, it tries (obviously, unsuccessfully) to use the system libc, although I try to point it to the path where the libraries should be taken from. He finds other libraries there, but libc stubbornly tries to take the system one.
I do something like this:

$ LD_LIBRARY_PATH=libs java -jar someapp.jar 

/usr/lib/x86_64-linux-gnu/libc.so: invalid ELF header

I don't have library sources, only .so-shka. Is there any way to tell him to use exactly the libc I want?

Answer 1

and if all this is done in chroot?

Answer 3

LD_LIBRARY_PATH=libs LD_PRELOAD=your_custom_libc.so java -jar someapp.jar
