本文主要是介绍win7下安装emacs 24.1问题汇总,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1.ecb加载时显示if: Symbol's value as variable is void: stack-trace-on-error,使用(setq stack-trace-on-error nil)屏蔽,就可以进入ecb了
从网上搜了下,除了这个问题还有两个问题,好像cedet-1.1正式版都修改了,也放在这备忘
吧
a. cedet最新版本为1.1beta,提示cedet-called-interactively-p的参数有问题
在cedet载入之前
(setq byte-compile-warnings nil)
b. ecb加载的时候显示错误信息,用下列语句屏蔽掉
(setq stack-trace-on-error nil)
c. ecb提示只兼容cedet版本 1.0.6pre ~ 1.0.9
在ecb最新版本中找到ecb-cedet-wrapper.el文件,第83行,将最高版本信息改写一下,比如改为如下
(defconst ecb-cedet-required-version-max '(1 1 4 9)...
另外,对于版本兼容问题,还可以修改ecb-2.40/ecb-updata.el中ecb-check-requirements
的;; check if vedet-version is correct
;; (when (or (not (boundp 'cedet-version))
;; (ecb-package-version-list<
;; (ecb-package-version-str2list cedet-version)
;; ecb-required-cedet-version-min)
;; (ecb-package-version-list<
;; ecb-required-cedet-version-max
;; (ecb-package-version-str2list cedet-version)))
;; (setq version-error (concat "cedet ["
;; cedet-required-version-str-min
;; ", "
;; cedet-required-version-str-max
;; "]")))
注释掉
2.cscope不能使用cscope-indexer,用cscope-indexer.py替代。
将cscope-indexer.py拷贝到的d:/emacs-24.1/bin下(目录可以变换,由修改的xscope.el
中的路径决定)。
修改xscope.el的cscope-unix-index-files-internal
(defun cscope-unix-index-files-internal (top-directory header-text args)
"Core function to call the indexing script."
(let ()
(save-excursion
(setq top-directory (cscope-canonicalize-directory top-directory))
(setq cscope-unix-index-process-buffer
(get-buffer-create cscope-unix-index-process-buffer-name))
(display-buffer cscope-unix-index-process-buffer)
(set-buffer cscope-unix-index-process-buffer)
(setq buffer-read-only nil)
(setq default-directory top-directory)
(buffer-disable-undo)
(erase-buffer)
(if header-text
(insert header-text))
(setq args (append args
(list "-v"
"-i" cscope-index-file
"-f" cscope-database-file
(if cscope-use-relative-paths
"." top-directory))))
(if cscope-index-recursively
(setq args (cons "-r" args)))
(setq args (cons "d:/emacs-24.1/bin/cscope-indexer.py" args));;修改的
(setq cscope-unix-index-process
(apply 'start-process "cscope-indexer"
cscope-unix-index-process-buffer
;;cscope-indexing-script
"c:/python27/python" args));;修改的
(set-process-sentinel cscope-unix-index-process
'cscope-unix-index-files-sentinel)
(process-kill-without-query cscope-unix-index-process)
)
))
这个python脚本会生成cscope.files并最终调用cscope生成cscope.out文件,但是这个脚本
有点小问题,需要修改一下,见下面的原脚本源码:
import getopt
import sys
import os
import re
def usage( ):
print( "cscope-indexer [ -v ] [-f database_file ] [-i list_file ] [ -l ] [ -r ]" )
pass
def listRecurse( rootDir, reg, fileName ):
fp = open( fileName, 'w' )
for root, dirs, files in os.walk( rootDir ):
for file in files :
if reg.search(file) != None :
fp.write( os.path.join( root, file ) )#这里少了空格,这样生成的
cscope.files会不能识别
fp.close()
pass
def lisrNoRecurse( rootDir, reg, fileName ):
fp = open( fileName, 'w' )
for file in os.listdir( rootDir ) :
if reg.search(file) != None :
fp.write( os.path.join( rootDir, file ) )#同上
fp.close()
pass
if __name__ == '__main__':
databaseFile = "cscope.out"
listFile = "cscope.files"
listOnly = False
recurse = False
verbose = False
dir = "."
try:
opts,args=getopt.getopt(sys.argv[1:],'vf:i:lr')
for flag,data in opts :
if flag == "-v":
verbose = True
elif flag == "-f":
if data == "":
usage()
os.system.exit()
else:
databaseFile = data
elif flag == "-i":
if data == "":
usage()
os.system.exit()
else:
listFile = data
elif flag == "-l":#这里如果使用C-c s L传进来的参数是L但是windows会
认成l,这样listOnly就True了,就不会生成cscope.out修改低下的代码
listOnly = True
elif flag == "-r":
recurse = True
else:
usage()
os.system.exit()
if len(args) != 0:
dir = args[0]
except getopt.GetoptError:
usage()
os.system.exit()
if verbose == True:
print( "Creating list of files to index ..." )
os.chdir( dir )
reg = re.compile('\.([chly](xx|pp)*|cc|hh)$')
if recurse == False :
lisrNoRecurse( dir, reg, listFile )
else:
listRecurse( dir, reg, listFile )
if verbose == True:
print( "Creating list of files to index ... done" )
if listOnly == True :;;上面说到的那个问题,简单注释掉吧,这个脚本的功能和
cscope的定义有稍许区别
os.system.exit()
if verbose == True :
print( "Indexing files ..." )
os.system( "cscope -b -i "+listFile+" -f "+databaseFile )
if verbose == True :
print( "Indexing files ... done" )
pass
修改后就可以使用了。打开一个源码文件,C-c s L或者C-c s I试一下,呵呵
