本文详细解析了Linux内核编译过程中遇到的两个常见错误，并提供了相应的解决方案。错误一涉及文件路径和标准头文件不存在的问题，通过选择正确的lib配置解决了此问题。错误二则指向了scsi_cmnd.h文件中的未定义引用，通过修改相关代码行避免了引用错误。本文旨在帮助开发者解决内核编译过程中的常见问题。

错误一：

In file included from /home/fpga/uClinux-dist/lib/libc/include/stdio.h:9,

from cryptlib.c:59:

/home/fpga/uClinux-dist/lib/libc/include/stdarg.h:3:28: machine/stdarg.h: No such file or directory In file included from cryptlib.c:59:

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:125: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:126: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:127: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:129: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:130: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:131: error: parse error before "va_list"

/home/fpga/uClinux-dist/lib/libc/include/stdio.h:132: error: parse error before "va_list" make[3]: *** [cryptlib.o] Error 1 make[3]: Leaving directory

`/home/fpga/uClinux-dist/lib/libssl/crypto' make[2]: *** [all] Error 1 make[2]: Leaving directory

`/home/fpga/uClinux-dist/lib/libssl' make[1]: *** [all] Error 2 make[1]: Leaving directory `

/home/fpga/uClinux-dist/lib' make: *** [subdirs] Error 1

解决办法：

	这个主要是因为  make menuconfig 的时候lib必须选none  而不是默认的uclib；

错误二：

drivers/built-in.o(.text+0x28c00): In function `scsi_dma_map':
/home/hayder/nios2-linux/linux-2.6/include/scsi/scsi_cmnd.h:154: undefined
reference to `dma_map_sg'
drivers/built-in.o(.text+0x28c48): In function `scsi_dma_unmap':
/home/hayder/nios2-linux/linux-2.6/include/scsi/scsi_cmnd.h:154: undefined
reference to `dma_unmap_sg

解决办法：

	修改  /home/hayder/nios2-linux/linux-2.6/include/scsi/scsi_cmnd.h:154:改为return 0；
