Semantic配置C++自动补全

先上pp, 点击查看大图:

( 我输入了"v.pu" 自动补全为v.push_back, 按一下tab确认)

Semantic is part of cedet(Collection of Emacs Development Environment Tools)

下面内容主要参考这篇文章:

1. Check out the latest cedet src:

cvs -z3 -d:pserver:anonymous@cedet.cvs.sourceforge.net:/cvsroot/cedet co -P cedet

2. Build cedet:

cd cedet
touch `find -name "Makefile"`
make bootstrap

3. Install:
copy the cedet dir to your emacs site-lisp:
/usr/share/emacs/23.0.60/site-lisp/ (press 'ctrl-h v load-path' in emacs to see it)

4. 配置 (.emacs)

(require 'cedet)

• 通过下面方式查看g++ include paths:

freestyler@effarr:~/program$ touch dummy.cpp
freestyler@effarr:~/program$ gcc -v -E -P dummy.cpp
使用内建 specs。

附录: g++ option:

-v Print (on standard error output) the commands executed to run the stages of compilation. Also print the version number of the compiler driver program and of the preprocessor and the compiler proper.

-E Stop after the preprocessing stage; do not run the compiler proper. The output is in the form of preprocessed source code, which is sent to the standard output.

-P Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers.
