先记下来，以免日后需要

 

先是设置home

Win+R  regedit打开注册表

software-GNU-Emacs 在右边新建字符串值 右击修改把你想要home在的目录进去，例如我的是D:/Emacs/emacs-23.2

安装cedet和ecb

下载cedet-1.0  ecb-2.40目前是最新的

 

Windows 下编译安装，在命令行下，进入到 cedit 的目录，输入命令：

> path/to/emacs/bin/emacs.exe -Q -l cedet-build.el -f cedet-build

在.emacs中加入

 

;; Load CEDET. ;; See cedet/common/cedet.info for configuration details. (load-file "D:/Emacs/emacs-23.2/cedet-1.0/common/cedet.el") (semantic-load-enable-minimum-features) (semantic-load-enable-code-helpers) (semantic-load-enable-guady-code-helpers) (semantic-load-enable-excessive-code-helpers) (semantic-load-enable-s-debugging-helpers) ;; Enable EDE (Project Management) features (global-ede-mode 1) (global-set-key [f4] 'speedbar)

 

把ecb解压到一个目录里

修改一些文件

1、ecb-analyse.e -(require 'semantic-analyze) +(require 'semantic/analyze) (require 'ecb-layout) (require 'ecb-common-browser) (require 'ecb-method-browser) 2、ecb-cedet-wrapper.el (require 'semantic) -(require 'semantic-ctxt) -(require 'semantic-analyze) -(require 'semanticdb) -(require 'semanticdb-find) -(require 'semanticdb-mode) +(require 'semantic/ctxt) +(require 'semantic/analyze) +(require 'semantic/db) +(require 'semantic/db-find) +(require 'semantic/db-mode) (defconst ecb-semantic-2-loaded (string-match "^2" semantic-version)) 3、ecb-method-browser.el (require 'ecb-speedbar) (require 'ecb-cedet-wrapper) -;; This loads the semantic-setups for the major-modes. -(require 'semantic-load) ;; various loads (require 'assoc) 减号代表要修改的 或者删除的

.emacs中添加

 ;;;;ECB (add-to-list 'load-path "D:/Emacs/emacs-23.2/ecb-2.40") (require 'ecb) ;;;;禁止每日提醒 (setq ecb-tip-of-the-day nil) ;;;; 各窗口间切换 (global-set-key [M-left] 'windmove-left) (global-set-key [M-right] 'windmove-right) (global-set-key [M-up] 'windmove-up) (global-set-key [M-down] 'windmove-down)

emacs只是一个编辑器，要想编译c++程序必须要有编译器

下载dev-cpp安装，它的编译器是mingw，正是我们想要的，我安装在D:/DEV-CPP下

自己安装gcc-core  gdb g++之类的话会很麻烦，这里用了一个偷懒的办法。

配置.emacs，用dev-cpp里面的编译器为emacs工作

(setq default-directory "D:/DEV-CPP/Bin") ;;=================================== ;;设置编译器========================== ;;=================================== ;;(setq compile-command (concat "D:/DEV-CPP/bin/g++ -g " "/"" buffer-file-name "/"")) (global-set-key (kbd "<f7>") 'smart-compile) (defun smart-compile() ;; "比较智能的C/C++编译命令 ;;如果当前目录有makefile则用make -k编译，否则，如果是 ;;处于c-mode，就用gcc -Wall编译，如果是c++-mode就用 g++ -Wall编译" (interactive) ;; 查找 Makefile (let ((candidate-make-file-name '("makefile" "Makefile" "GNUmakefile")) (command nil)) (if (not (null (find t candidate-make-file-name :key '(lambda (f) (file-readable-p f))))) (setq command "make -k ") ;; 没有找到 Makefile ，查看当前 mode 是否是已知的可编译的模式 (if (null (buffer-file-name (current-buffer))) (message "Buffer not attached to a file, won't compile!") (if (eq major-mode 'c-mode) (setq command (concat "D:/DEV-CPP/bin/gcc.exe -Wall -o " ;;你要明确知道自己的编译器在 哪里, (file-name-sans-extension ;;这样,用你的 gcc.exe的地址代替这里的D:/Dev-Cpp/bin/gcc.exe (file-name-nondirectory buffer-file-name)) ;;注意,这里的路径的斜杠 和vista的习惯相反,你要注意修改 " " (file-name-nondirectory buffer-file-name) " -g -lm ")) (if (eq major-mode 'c++-mode) (setq command (concat "D:/DEV-CPP/bin/g++.exe -Wall -o " ;;还有这里的g++,也同gcc一样... (file-name-sans-extension (file-name-nondirectory buffer-file-name)) " " (file-name-nondirectory buffer-file-name) " -g -lm ")) (message "Unknow mode, won't compile!"))))) (if (not (null command)) (let ((command (read-from-minibuffer "Compile command: " command))) (compile command)))))

上面default-directory是让emacs找到devcpp的编译器

下面是配置一个快捷键f7，省得每次都 gcc -Wall -g exp.cpp -o exp

到这里就应该可以调用以下的命令了

ecb-activiate 来激活ecb，可以看到ecb窗口

打开一个cpp文件 按下f7应该可以编译文件

M-x gdb应该可以进入调试模式

下面是代码折叠的配置

;;; hide-show (setq hs-allow-nesting t) (add-hook 'c-mode-common-hook (lambda () (hs-minor-mode 1) )) (add-hook 'emacs-lisp-mode-hook (lambda() (hs-minor-mode 1))) (add-hook 'tcl-mode-hook (lambda () (hs-minor-mode 1) )) (define-key hs-minor-mode-map [?/C-/ ?H] 'hs-hide-all) (define-key hs-minor-mode-map [?/C-/ ?S] 'hs-show-all) (define-key hs-minor-mode-map [?/C-/ ?h] 'hs-hide-block) (define-key hs-minor-mode-map [?/C-/ ?s] 'hs-show-block) (define-key hs-minor-mode-map [?/C-/ ?l] 'hs-hide-level) (define-key hs-minor-mode-map [?/C-/ ?t] 'hs-toggle-hiding)
