SourceInsight 精确导入Linux kernel源码的方法 --转载未测试
相信有很多人用 SourceInsight 查看 Linux Kernel 源码，但导入源码时会遇到一些问题。
1、如果把整个源码树都导入进去，查看符号定义的时候，会发现有大量重复定义，很难找到正确的位置
2、如果手动导入只和该硬件平台相关的源码，工作量太大
本帖提供了一个方法，可用脚本生成只和该硬件平台相关的源码的文件列表，然后通过该文件列表，将相应文件导入 SourceInsight 。
以下是步骤，共4步：
1、新建 SourceInsight 项目
先不要导入文件，停在如下界面：
2、完整编译内核，将编译时输出的信息保存到一个文件中
例如：
- make ARCH=arm > build_log.txt
build_log.txt 文件中内容大致如下：
- CC init/main.o
- CHK include/generated/compile.h
- CC init/do_mounts.o
- HOSTCC usr/gen_init_cpio
- CC arch/arm/vfp/vfpmodule.o
- CC arch/arm/kernel/elf.o
- AS arch/arm/kernel/entry-armv.o
- AS arch/arm/vfp/entry.o
- AS arch/arm/kernel/entry-common.o
- CC arch/arm/kernel/irq.o
- AS arch/arm/vfp/vfphw.o
- GEN usr/initramfs_data.cpio
- CC arch/arm/kernel/opcodes.o
3、生成文件列表
下载 帖子 最后面的附件，解压后是 linux shell 脚本。
编辑脚本两个变量，ARCH 和 MACH，MACH是平台的名字。如果你用的平台对应 arch/arm/mach-at91 的话，就改成 MACH=at91，以此类推。
在内核源码目录下执行：
- ./sg.sh build_log.txt file_list.txt
复制代码
这样，SourceInsight 需要的 文件列表 file_list.txt 就生成了。里面的内容大致如下：
4、导入文件列表
回到 SourceInsight，点击窗口右下角 help 按钮上方的 “add from list” 按钮导入生成的 file_list.txt 文件。
到此为止，文件导入完成了。重新打开工程，会提示同步、构建，之后就可以正常的查看源码了。
这样导入的文件和硬件平台是完全对应的。
下面是本帖的核心，就是这个脚本，有兴趣的可以看看：
#!/bin/sh
ARCH=arm
MACH=at91
FILE_IN=$1
FILE_OUT=$2
# .c
SOURCE_LIST=""
# generated file list
FILE_LIST=""
# nest depth for function get_includes()
NEST_DTPTH=0
# recursive function, used to get included files from files.
# result is stored in FILE_LIST
# $1 : file list, e.g. "fs/ext4/file.c fs/ext4/fsync.c"
get_includes()
