Eclipse CDT 导入 Makefile 构建的 C/C++ 工程
File -> New -> Makefile Project with Existing Code
选择源码目录，语言选择C语言。如果是 Linux 环境，则选中 Linux GCC，Mac 环境则选择 MacOSX GCC，Windows 下用 Eclipse 则可以选择 MinGW GCC。
Project -> Make Target -> Create，建立 all 和 clean 两个 Targets。
在 Make Target 的 View 里面选择刚刚建立的项目的 all 来构建项目
构建结束后，Run -> Debug As -> Local C/C++ Application -> gdb/mi，调试选项可以在 Debug Configuration 中设置。
其中 gdb/mi 和 gdb 的区别，在网上搜来如下解释：
gdb and gdb/mi are essentially the same, except that gdb/mi lets you
select the MI protocol version and command set to use (MI - or Machine
Interface - is how Eclipse communicates with gdb, rather than using
the normal gdb command-line interface). This is useful if you want to
do something not supported by the defaults, or have a non-standard gdb,
such as used on Mac OS X. gdbserver is a very lightweight debug server
used for debugging embedded systems. **The normal gdb/mi commands are
used, but gdb must be told to connect to a gdbserver running on a remote
system.** There's an extra tab for specifying this information.
