source insight 精确导入内核文件

原文链接

1. 环境

目前使用的是 4.00.0120 版本的 source insight

使用 samba 服务，来访问 ubuntu 的代码；

2. 导入工作

2.1 关闭自动添加新文件功能

Options => Preferences => General

将下图的 Add new files automatically 勾去除；

2.2 完整编译内核，将编译时输出的信息保存到一个文件中

# 将之前的编译清除

make distclean

# 配置自己的单板 xxx 为自定义的名字

make xxx_defconfig

# 编译并记录编译过程

make zImage -j8 2>&1 | tee build_log.txt

 # 将下面脚本命名为 sg.sh；给予 777 权限；

#!/bin/sh

MACH=fsl
FILE_IN=$1
FILE_OUT=$2

# generated file list

#   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。

# 通过脚本来生成需要导入的文件列表

./sg.sh build_log.txt file_list.txt

2.3 将源码文件导入工程

# 新建 SourceInsight 项目，先不要导入文件，停在如下界面：

 # 导入文件列表；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。
