Running a container's ELF file without container

Question

I got an ELF file of type ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, stripped which I want to run in a normal regular linux machine (not a container)

Sadly I get the error No such file or directory when trying to execute.

I eventually want to debug said ELF and it will be harder to do in a container.

Was googling for hours and couldnt find a simple solution.

Notice that the file is an "shared object", which is a shared library (a.k.a. a DLL). You can't execute it, you need a program ("executable") that is linked to the library. — Some programmer dude, Apr 05 '19 at 09:57
You're right. Is there any simple way to run that? It is even got a main function — Daniel Cohen, Apr 05 '19 at 10:18
You can't "run" a library, end of story really. And while a library *might* have a `main` function it's not special like it is in an executable program, and won't be called automatically. — Some programmer dude, Apr 05 '19 at 10:20
@Someprogrammerdude You are mistaken: this is an executable, and you *can* run it. — Employed Russian, Apr 07 '19 at 22:00

ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, stripped

This binary is linked to use musl libc, which is not installed on your system.

No such file or directory

This error is slightly confusing. What's missing is not your binary, but the iterpreter (/lib/ld-musl-x86_64.so.1) which it requires.

It may be possible to install musl in parallel with existing GLIBC, though I didn't find a definitive yes/no answer.

I ended up running it on Alpine which solved the problem – Daniel Cohen Apr 08 '19 at 15:22 — Daniel Cohen, Apr 08 '19 at 15:22

musl is used to compile portable static binaries. Something went wrong with the compilation of the program you are trying to run. The flag '--static' should have been passed to the program that was compiled, which would result in a

ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, with debug_info, not stripped

An example on how to compile such a program:

CC=musl-gcc CFLAGS="--static" ./Configure
make
