如何解决“加载共享库时出错"?尝试使用qemu-arm运行arm二进制文件时? [英] How to solve "error while loading shared libraries" when trying to run an arm binary with qemu-arm?

问题描述

我正在运行Linux Mint 14，安装了qemu，qemu-user和gnueabi工具链.我用arm-linux-gnueabi-gcc test.c -o test编译了test.c.

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.

当我尝试运行qemu-arm /usr/arm-linux-gnueabi/lib/ld-linux.so.3 test

我收到一条错误消息:test: error while loading shared libraries: test: cannot open shared object file: No such file or directory.正如我之前尝试过的那样，运行qemu-arm test会给出/lib/ld-linux.so.3: No such file or directory

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

但是，该文件确实存在并且可以访问.

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'

有人知道我如何让qemu运行arm程序而不必模拟整个arm Linux内核吗?

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

test.c是

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

和file test是

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

推荐答案

如果要在没有Linux的情况下运行 ARM ，则至少需要一个不同的编译器. arm-linux-gnueabi-gcc是 Linux 的编译器.编译器和libc是紧密链接的.您将需要一个带有 qemu 的可移植层的newlib编译器. ^移植newlib

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}

请参阅:巴劳和 Google newlib + qemu . newlib端口托管在 Github 上，与 Balau 博客相同.

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

通常，非Linux gcc称为arm-none-eabi-gcc.某些配置脚本可以识别前缀 arm-none-eabi-.

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