【记录】Cygwin下交叉编译Linux内核在配置后去make编译

Cygwin crifan 3852浏览 0评论

【背景】

折腾:

【记录】Cygwin下用arm-xscale-linux-gnueabi交叉编译Linux内核

期间,在配置内核:

【记录】Cygwin下交叉编译Linux内核时用make xxx_defconfig去调用默认配置

【记录】Cygwin下交叉编译Linux内核时用make menuconfig去确认和修改配置

后,接着去交叉编译。

【折腾过程】

1.为了保险起见,还是加上ARCH和CROSS_COMPILE去编译:

make ARCH=arm CROSS_COMPILE=arm-xscale-linux-gnueabi- zImage

结果是,开始可以编译:

$ make ARCH=arm CROSS_COMPILE=arm-xscale-linux-gnueabi- zImage

2.后来出现“scripts/mod/modpost.h:119:2: error: unknown type name ‘Elf32_Section’”的错误:

【已解决】Cygwin下交叉编译Linux内核make zImage时出错:scripts/mod/modpost.h:119:2: error: unknown type name ‘Elf32_Section’

3.然后继续编译,又出现"scripts/mod/sumversion.c:12:26: fatal error: linux/limits.h: No such file or directory"的错误:

【已解决】Cygwin下交叉编译Linux内核make zImage时出错:scripts/mod/sumversion.c:12:26: fatal error: linux/limits.h: No such file or directory

4.然后,就是,很长时间的,顺利的编译了。然后最终,就正常编译完成了:

【总结】

此处,在Cygwin下,用之前建立的arm-xscale-linux-gnueabi交叉编译器,在配置好之后,去用:

make ARCH=arm CROSS_COMPILE=arm-xscale-linux-gnueabi- zImage

去编译此处的linux-2.6.19.1,遇到的问题和解决办法分别是:

1.错误:scripts/mod/modpost.h:119:2: error: unknown type name ‘Elf32_Section’

办法:

修改:

linux-2.6.19.1\scripts\mod\modpost.h

为:

#include <unistd.h>
#include <elf.h>
  
#ifdef __CYGWIN__
#define uint16_t __uint16_t
#define uint32_t __uint32_t
typedef uint16_t Elf32_Section;
typedef uint16_t Elf64_Section;
#endif
 
#include "elfconfig.h"
 
#if KERNEL_ELFCLASS == ELFCLASS32
 
#define Elf_Ehdr    Elf32_Ehdr
#define Elf_Shdr    Elf32_Shdr
#define Elf_Sym     Elf32_Sym
#define Elf_Addr    Elf32_Addr
#define Elf_Section Elf32_Section
 
#ifndef __CYGWIN__
#define ELF_ST_BIND ELF32_ST_BIND
#define ELF_ST_TYPE ELF32_ST_TYPE
#endif
 
#define Elf_Rel     Elf32_Rel
#define Elf_Rela    Elf32_Rela
#define ELF_R_SYM   ELF32_R_SYM
#define ELF_R_TYPE  ELF32_R_TYPE
#else
 
#define Elf_Ehdr    Elf64_Ehdr
#define Elf_Shdr    Elf64_Shdr
#define Elf_Sym     Elf64_Sym
#define Elf_Addr    Elf64_Addr
#define Elf_Section Elf64_Section
#define ELF_ST_BIND ELF64_ST_BIND
#define ELF_ST_TYPE ELF64_ST_TYPE
 
#define Elf_Rel     Elf64_Rel
#define Elf_Rela    Elf64_Rela
#define ELF_R_SYM   ELF64_R_SYM
#define ELF_R_TYPE  ELF64_R_TYPE
#endif
 
/* copy from linux-2.6.24includeasm-x86 */
#define R_386_32       1
#define R_386_PC32     2
/* copy from linux-2.6.24includeasm-arm */
#define R_ARM_PC24     1
#define R_ARM_ABS32    2
/* copy from linux-2.6.24includeasm-mips */
#define R_MIPS_32      2
#define R_MIPS_26      4
#define R_MIPS_HI16    5
#define R_MIPS_LO16    6
 
/* The 64-bit MIPS ELF ABI uses an unusual reloc format. */
typedef struct

【已解决】Cygwin下交叉编译Linux内核make zImage时出错:scripts/mod/modpost.h:119:2: error: unknown type name ‘Elf32_Section’

2.错误:scripts/mod/sumversion.c:12:26: fatal error: linux/limits.h: No such file or directory

办法:

把:

linux-2.6.19.1\scripts\mod\sumversion.c

从:

#include <linux/limits.h>

改为:

//#include <linux/limits.h>
#include <limits.h>

详见:

【已解决】Cygwin下交叉编译Linux内核make zImage时出错:scripts/mod/sumversion.c:12:26: fatal error: linux/limits.h: No such file or directory
