Cannot run on Alpine Linux

[maphe]

I'm trying to run the realesrgan-ncnn-vulkan executable on an Docker container running on Alpine, and getting errors.

My Apline Docker setup includes installing glibc via the following line

RUN apk add --no-cache vulkan-loader vulkan-tools glibc-compat

When I try to run it, I'm getting the following error:

Error loading shared library libmvec.so.1: No such file or directory (needed by /app/models/realesrgan/realesrgan-ncnn-vulkan)
Error relocating /app/models/realesrgan/realesrgan-ncnn-vulkan: _ZGVbN4v_expf: symbol not found

The file itself (libmvec.so.1) exists in /usr/glibc-compat/lib but my guess is that the executable can't access it there.

I've tried a few things, including:

ln -sf /usr/glibc-compat/lib/* /usr/lib/

but this is just changing the error to:

Error relocating /usr/lib/libmvec.so.1: unsupported relocation type 37
# ...same error duplicated 20 times...
Error relocating /usr/lib/libmvec.so.1: _rtld_global_ro: symbol not found
Error relocating /app/models/realesrgan/realesrgan-ncnn-vulkan: _ZGVbN4v_expf: symbol not found

I'll take any idea I can try out. Thanks

It's a mismatched library / loader / possibly ELF version vs the only downloadable build, just build from source.
