交叉编译内核模块ARM [英] Cross-compiling kernel module for ARM

问题描述

我要交叉编译的 rtl8192cu驱动程序的目标ARM埃的（的BeagleBoard）的，基于x86的Ubuntu 13.04。

交叉编译prerequisites：

1. rtl8192cu驱动程序


2. 交叉工具链的（codeSourcery / ARM埃Linux的gnueabi）的


3. 内核源代码

由于这个原因，我复制的内核源代码的 usr / src目录的BeagleBoard的目录，Ubuntu的机器上的（它们HEVE被编上的BeagleBoard，因为我需要重新编译内核）。

运行制作的交叉编译，我得到这个错误：

 让ARCH =手臂CROSS_COMPILE=/home/demetres/$c$cSourcery/Sourcery_$c$cBench_Lite_for_ARM_GNU_Linux/bin/arm-none-linux-gnueabi- -C /家庭/ demetres /桌面/ KS1 M = /家庭/ demetres /桌面/ rtl3模块

如果我跑文件fixdep 我得到：

  fixdep：ELF 32位LSB的可执行文件，ARM版本1（SYSV），动态链接（使用共享库），为GNU / Linux 2.6.16，不可剥离
 

这是有道理的，因为fixdep，是内核的一部分来源的（编译在ARM平台）的。

解决方案

fixdep是ARM二进制和你想的x86机器（英特尔）上运行。您可能必须重新编译内核资源（只是让他们），并尝试再次交叉编译。

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

Cross-compile prerequisites:

1. rtl8192cu driver
2. Cross-toolchain (CodeSourcery / arm-angstrom-linux-gnueabi)
3. kernel sources

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).

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

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

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

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

解决方案

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.
