arm can't run arm compiled binary

2018-07-01 04:03:57

I'm running Linux Mint 14 with qemu, qemu-user, and the gnueabi toolchain installed. I compiled test.c with arm-linux-gnueabi-gcc test.c -o test .

When I try and run qemu-arm /usr/arm-linux-gnueabi/lib/ld-linux.so.3 test

I get an error saying: test: error while loading shared libraries: test: cannot open shared object file: No such file or directory . Running qemu-arm test , as I've previously tried, gives /lib/ld-linux.so.3: No such file or directory

However, the file does exist and is reachable.

$ stat /usr/arm-linux-gnueabi/lib/ld-linux.so.3
  File: `/usr/arm-linux-gnueabi/lib/ld-linux.so.3' -> `ld-2.15.so'

Does anyone know how I can make qemu run an arm program without having to emulate an entire arm Linux kernel?

test.c is

#include <stdio.h>
int main() {
    printf("this had better workn");
}

and file test is

test: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.31, BuildID[sha1]=0xf2e49db65394b77c77ee5b65b83c0cc9220cbfc0, not stripped

If you want to run ARM without Linux, then you need a different compiler (at least). arm-linux-gnueabi-gcc is a compiler for Linux . The compiler and libc are intimately linked. You will need a newlib compiler with a portability layer for qemu.porting newlib

See: Balau and Google newlib+qemu. A newlib port is hosted at Github and seems to the same as the Balau blog.

Typically a non-Linux gcc is called arm-none-eabi-gcc . The prefix arm-none-eabi- is recognized by some configure scripts.

you can run the example by providing a path to the arm-linux-gnueabi shared libs using the -L flag.

qemu-arm -L /usr/arm-linux-gnueabi/

also make sure the LD_LIBRARY_PATH is not set.

unset LD_LIBRARY_PATH

I also met this problem when running a C program with assembly code. My solution is to build the executable with the option "-static", for instance

arm-linux-gnueabi-gcc -static -g main.c square.s

Then

qemu-arm a.out

will not report the error saying "can not find the /lib/ld-linux.so.3".

The only drawback is that the executable could be with a large size. But it's helpful when you just want to test your code.

Of course, you can go with the method from Balau(see artless noise's answer). But if you don't want to feel frustrated by something like "UART serial ports" in this step, which is only to run a simple "test" function, go for a try of my fix.
