问题描述

我想在 x86 Ubuntu 13.04 上交叉编译 rtl8192cu 驱动程序,目标是 ARM Angstrom (BeagleBoard).

I want to cross-compile rtl8192cu driver targeting ARM Angstrom (BeagleBoard), on x86 Ubuntu 13.04.

交叉编译先决条件:

  1. rtl8192cu 驱动程序
  2. 跨工具链(CodeSourcery/arm-angstrom-linux-gnueabi)
  3. 内核源

出于这个原因,我复制了 BeagleBoard 的内核源代码 usr/src 目录,在 Ubuntu 机器上(它们已经在 BeagleBoard 上编译,因为我需要重建内核).

For this reason, I copied kernel sources usr/src directory of BeagleBoard, on Ubuntu machine (they heve been compiled on BeagleBoard, as I needed to rebuild the kernel).

运行 make 进行交叉编译,出现此错误:

Running make for cross-compile, I get this error:

make ARCH=arm CROSS_COMPILE=/home/demetres/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin/arm-none-linux-gnueabi- -C /home/demetres/Desktop/ks1 M=/home/demetres/Desktop/rtl3  modules
make[1]: Entering directory `/home/demetres/Desktop/ks1'
  CC [M]  /home/demetres/Desktop/rtl3/core/rtw_cmd.o
/bin/sh: scripts/basic/fixdep: cannot execute binary file
make[2]: *** [/home/demetres/Desktop/rtl3/core/rtw_cmd.o] Error 126
make[1]: *** [_module_/home/demetres/Desktop/rtl3] Error 2
make[1]: Leaving directory `/home/demetres/Desktop/ks1'
make: *** [modules] Error 2

如果我运行 file fixdep 我得到:

If I run file fixdep I get:

fixdep: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

这是有道理的,因为 fixdep 是内核源代码的一部分(在 ARM 平台上编译).

This makes sense, as fixdep, is part of kernel sources (compiled on ARM platform).

我的查询是:该程序是否正确,我该如何解决此错误?

My query is: Is that procedure correct and how can I fix this error?

运行make V=1:

推荐答案

fixdep 是一个 ARM 二进制文件,您正试图在 x86 机器 (intel) 上运行它.您可能必须重新编译内核资源(只需制作它们)并再次尝试交叉编译.

fixdep is an ARM binary and you are trying to run it on x86 machine(intel). You probably have to recompile kernel resources (just make them) and try cross compiling again.
