This question is posted on RE.SE . Here is the original uncut version of the question.
First I will give a quick summary of my environment
Device: Samsung Galaxy M20 (m20lte)
SoC: Exynos 7904 (with Mali-G71 GPU)
OS: Android 10 (Stock ROM with root using Magisk)
Kernel: 4.4.177
SELinux is disabled (set to permissive mode)
Vulkan API version: 1.1.108
Chroot environment: Debian 11 (arm64) running on Linux Deploy, with full root access. Directories like /dev, /proc, /data, /system, /sdcard are mounted into the chroot.
I know this device support Vulkan API (Vulkan loader avaliable at /system/lib64/libvulkan.so).
Normal Android apps can load and use Vulkan APIs without any problems. For example:
- Vulkan Caps Viewer can display Vulkan information on this device
- GeekBench 5,
Computesection has an option to compute with GPU using Vulkan API, and it works well
I cannot load libvulkan.so from /system/lib64/libvulkan.so by running program in the chroot.
For example, I created a simple c source (named dlopen.c):
#include <stdio.h>
#include <dlfcn.h>
int main() {
void *handle = dlopen("libvulkan.so", RTLD_LAZY);
if (!handle) {
printf("Cannot load libvulkan.so\n");
} else {
printf("Loaded libvulkan.so\n");
}
return 0;
}
Compile it using gcc: gcc dlopen.c -ldl -o dlopentest
Setup the environment variable LD_LIBRARY_PATH=/system/lib64/ or symlink /system/lib64/libvulkan.so to (folder in chroot) /lib/aarch64-linux-gnu/libvulkan.so and /lib/aarch64-linux-gnu/libvulkan.so.1
Finally run it using ./dlopentest, the program always print Cannot load libvulkan.so
Using strace, but nothing weird found:

I'm not sure about /lib/aarch64-linux-gnu/libc.so, since instead of being a symlink to libc.so.6 or a real .so file, it's some kind of ld script. But replacing it with a symlink to libc.so.6 makes no change.
vulkaninfo also reports an error:
ERROR at /build/vulkan-tools-3Ouhix/vulkan-tools-1.2.162.0+dfsg1/vulkaninfo/vulkaninfo.h:628: Failed to initialize: Vulkan loader is not installed, not found, or failed to load.
strace result is pretty much the same as my dlopentest, so I won't include it here.
(actually I don't know what section to put this, so I put it here)
Running file on /system/lib64/libvulkan.so:
/system/lib64/libvulkan.so: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, BuildID[md5/uuid]=e749d3c10d92fcef9b84402783d311f8, stripped
It's dynamically linked, so I run ldd on it and notice the following line:
/system/lib64/libvulkan.so: /lib/aarch64-linux-gnu/libc.so: version `LIBC' not found (required by /system/lib64/libvulkan.so)
/system/lib64/libvulkan.so: /lib/aarch64-linux-gnu/libdl.so: version `LIBC' not found (required by /system/lib64/libvulkan.so)
And other lines from .so libraries in /system/lib64 claimed the same thing.
So I check the /system/lib64/libc.so, and found that it's a symbolic link to /apex/com.android.runtime/lib64/bionic/libc.so.
So I mounted /apex/com.android.runtime to chroot.
After doing so, ldd found no more problem:

- Why it does not work (why I cannot load
libvulkan.soproperly)? - How to fix it?
I know this section might not related to the question, but I still want to include it, to avoid possible XY problem.
I want to run War Thunder (a game, and it supports x86_64 Linux). I run it on box64 and it runs until report cannot initialize Vulkan. FYI, Vulkan is the only supported render backend for the game on Linux, so I can't use OpenGL or something.
The game require the real libc (not Android one), so I can't run it on proot, and distro-proof on Termux is too complicated compared to Linux Deploy.
Finally, thank you for reading this I just want to run War Thunder :)
